Single Mode 10G SFP+ Module: Price, Types & Buying Guide

A single mode 10G SFP+ module is the most practical choice when you need stable, long-distance 10G fiber connectivity without sacrificing compatibility or future scalability. For most enterprise networks, data centers, and service providers, it offers the best balance between transmission distance, cost control, and deployment flexibility.

Unlike multimode 10G SFP+ modules that are limited to short distances, single mode 10G SFP+ are designed for links ranging from 10km to 80km and beyond, making them ideal for building-to-building connections, campus networks, metro networks, and backbone upgrades. This extended reach allows network planners to simplify infrastructure design while maintaining consistent 10Gbps performance.

From a buying perspective, single mode 10G SFP+ modules are no longer a “premium-only” option. With the availability of cost-effective LINK-PP compatible modules, enterprises can now deploy long-distance 10G links at a fraction of traditional OEM pricing—without compromising on reliability or standards compliance. This shift has made single mode 10G SFP+ a mainstream choice rather than a niche solution.

In this guide, we focus on what matters most for buyers:
which type of single mode 10G SFP+ module to choose, how pricing differs between LR, ER, and ZR, how compatibility affects your purchase decision, and how to avoid overpaying for features you don’t need. Whether you are upgrading an existing network or planning a new 10G deployment, this article will help you make a confident, cost-effective decision.

1️⃣ What Is a Single Mode 10G SFP+ Module?

A single mode 10G SFP+ module is a hot-swappable optical transceiver that delivers 10Gbps data transmission over single mode fiber for medium- to long-distance network links. It is designed for scenarios where multimode fiber cannot meet distance or scalability requirements.

At a functional level, a single mode 10G SFP+ module converts electrical signals from a switch or router into optical signals, transmits them over single mode fiber, and converts them back at the receiving end. It follows the SFP+ MSA (Multi-Source Agreement) and is commonly deployed in standard SFP+ ports on switches, routers, and network interface cards.

What truly defines this module—and influences buying decisions—are three core characteristics:

Long-Distance Transmission by Design

Single mode 10G SFP+ modules typically operate at 1310nm or 1550nm wavelengths, allowing light to travel much farther with minimal signal loss. Depending on the model, transmission distances commonly include:

• 10km (10GBASE-LR) for enterprise and campus networks

• 40km (10GBASE-ER) for metro and inter-building links

• 80km+ (10GBASE-ZR) for backbone and telecom applications

This makes single mode modules the preferred choice when network expansion or future relocation is expected.

Optimized for Single Mode Fiber Infrastructure

Unlike multimode solutions that rely on OM3 or OM4 fiber, single mode 10G SFP+ modules use OS2 single mode fiber, which:

• Supports longer distances without repeaters

• Offers better long-term scalability

• Is less sensitive to modal dispersion

From a cost perspective, while single mode optics may be slightly higher in unit price, they often reduce total cost of ownership by avoiding future fiber replacement.

Standards-Based and Widely Compatible

Single mode 10G SFP+ modules are built to comply with IEEE 802.3ae standards, ensuring interoperability across network equipment. When properly coded, they can be used in:

• Data center switches

• Enterprise aggregation and core layers

• Telecom and service provider networks

For buyers, this means a single mode 10G SFP+ module is not a proprietary solution—it is a standards-driven, vendor-agnostic component that fits into most modern 10G network designs.

🎯 In short, a single mode 10G SFP+ module is not just a higher-distance alternative to multimode—it is a strategic choice for networks that prioritize reach, flexibility, and long-term value over short-range cost savings.

2️⃣ Main Types of Single Mode 10G SFP+ Modules

Single mode 10G SFP+ modules are primarily differentiated by transmission distance and wavelength, and choosing the right type directly affects both network reliability and total cost. In most buying scenarios, the decision comes down to selecting LR, ER, or ZR—each designed for a specific distance range and deployment environment.

10GBASE-LR SFP+ Module (10km)

10GBASE-LR SFP+ is the most widely used single mode 10G SFP+ module and the default choice for most enterprise networks.

• Wavelength: 1310nm

• Maximum distance: up to 10km over OS2 single mode fiber

• Typical use cases:

  • Data center interconnections

  • Campus and enterprise core networks

  • Building-to-building links

From a cost-performance standpoint, LR offers the best balance. It delivers sufficient reach for the majority of deployments while maintaining lower power consumption and pricing compared to ER and ZR.
If your link distance is under 10km, LR is almost always the most cost-effective option.

10GBASE-ER SFP+ Module (40km)

10GBASE-ER SFP is designed for long-distance links where LR is no longer sufficient, but ultra-long-haul solutions are unnecessary.

• Wavelength: 1550nm

• Maximum distance: up to 40km

• Typical use cases:

  • Metro networks

  • Long-distance enterprise interconnections

  • Service provider access networks

ER modules provide a higher optical power budget, allowing them to maintain signal integrity over extended distances. However, this comes at a higher module cost and increased sensitivity to optical power levels.
Choose ER only when your actual fiber distance exceeds 10km, as using ER for short links usually adds cost without practical benefit.

10GBASE-ZR SFP+ Module (80km+)

10GBASE-ZR is intended for ultra-long-distance transmission and is typically used in telecom and backbone environments.

• Wavelength: 1550nm

• Maximum distance: 80km or more (depending on fiber quality and link design)

• Typical use cases:

  • Backbone and core networks

  • Long-haul telecom links

  • High-power metro aggregation

ZR modules operate at the highest optical power levels and often require careful link planning, including attenuation and optical budget management.
For most enterprises, ZR is unnecessary—but for service providers and large-scale networks, it enables long-distance 10G connectivity without additional amplification equipment.

Quick Buying Guide: LR vs ER vs ZR

• Choose 10GBASE-LR if your link distance is ≤10km and cost efficiency matters

• Choose 10GBASE-ER if your link distance is between 10km and 40km

• Choose 10GBASE-ZR only if your network truly requires 80km+ reach

🎯 Selecting the correct type ensures you avoid overpaying for excess distance while maintaining stable, standards-compliant 10G performance—a critical factor in any transactional purchasing decision.

3️⃣ Key Specifications to Compare Before Buying

When purchasing a single mode 10G SFP+ module, the right choice depends less on brand names and more on how well key specifications match your real deployment needs. Comparing these parameters upfront helps avoid overspending, compatibility issues, and performance mismatches.

Transmission Distance and Optical Budget

The first and most critical specification is supported transmission distance, which directly determines whether the module will work reliably on your fiber link.

• Common options: 10km (LR), 40km (ER), 80km+ (ZR)

• Optical budget increases with distance, but so does cost

• Choosing more distance than required rarely adds value

Buying rule: match the module distance to your actual fiber length, not your maximum theoretical requirement.

Wavelength (1310nm vs 1550nm)

Single mode 10G SFP+ modules typically operate at 1310nm or 1550nm, and this affects both reach and deployment flexibility.

• 1310nm: optimized for short-to-medium distances (LR)

• 1550nm: supports longer distances with lower attenuation (ER / ZR)

While wavelength does not usually affect switch compatibility, it must match the module on the other end of the link.

Compatibility and Coding

Compatibility is a key transactional concern, especially when buying third-party modules.

• Must comply with SFP+ MSA and IEEE 802.3ae

• EEPROM coding determines vendor compatibility

• Pre-coded modules support plug-and-play installation

Tip: verify compatibility with your specific switch or router model, not just the brand name.

Digital Optical Monitoring (DOM)

DOM provides real-time visibility into module performance and is increasingly expected in modern networks.

Key monitored parameters include:

• Optical transmit and receive power

• Module temperature

• Supply voltage

For operational stability and troubleshooting, DOM support is strongly recommended, particularly in data center and service provider environments.

Power Consumption and Thermal Performance

Higher-distance modules typically consume more power, which impacts switch thermal design.

• LR modules: lower power consumption

• ER / ZR modules: higher power and heat output

• Adequate airflow and cooling are essential for long-haul deployments

Ignoring thermal considerations can shorten module lifespan and affect overall network reliability.

Operating Temperature Range

Different deployment environments require different temperature tolerances.

• Commercial temperature: 0°C to 70°C (most enterprise use cases)

• Industrial temperature: -40°C to 85°C (outdoor or harsh environments)

Choosing an industrial-grade module only makes sense if your environment truly demands it.

Connector Type

Most single mode 10G SFP+ modules use a duplex LC connector, which:

• Is widely supported

• Simplifies fiber management

• Matches standard OS2 single mode patch cables

Always confirm connector type to avoid unexpected cabling changes.

🎯 In summary, the best single mode 10G SFP+ module is not the one with the highest specifications—but the one whose specifications align precisely with your distance, environment, and compatibility requirements. This approach ensures optimal performance while keeping procurement costs under control.

4️⃣ Single Mode 10G SFP+ Module Compatibility Guide

Compatibility is often the deciding factor when buying a single mode 10G SFP+ module, especially in multi-vendor network environments.

Even when a module meets all technical standards, improper coding or vendor restrictions can prevent it from being recognized by your equipment.

To avoid deployment issues, compatibility should be evaluated at three levels: standards compliance, vendor recognition, and real-world interoperability.

Standards Compliance Comes First

At a minimum, a single mode 10G SFP+ module should comply with:

• SFP+ Multi-Source Agreement (MSA)

• IEEE 802.3ae (10GbE standard)

Modules that follow these standards ensure correct electrical interfaces, optical characteristics, and signal behavior.
Standards compliance is non-negotiable, but it alone does not guarantee full compatibility.

OEM vs LINK-PP Compatible Modules

Many switch vendors use proprietary EEPROM coding to identify approved transceivers.

• OEM modules:

  • Guaranteed recognition

  • Significantly higher cost

• LINK-PP compatible modules:

  • Pre-coded to match specific vendors

  • Substantially lower cost

  • Widely used in enterprise and data center networks

Modern LINK-PP single mode 10G SFP+ modules can achieve full functional equivalence to OEM optics when properly coded and tested.

Brand and Platform Compatibility

A well-coded single mode 10G SFP+ module can work seamlessly with most major networking platforms, including:

• Cisco

• Juniper

• HPE / Aruba

• Arista

• Dell

• Huawei

• MikroTik

Important: compatibility depends on the exact switch model and software version—not just the brand name. Always verify platform-specific support.

Same Module Type at Both Ends

For stable 10G links:

• Both ends must use the same module type (LR-to-LR, ER-to-ER, etc.)

• Wavelengths must match

• Fiber type must be single mode (OS2)

Mixing different distances or wavelengths typically results in link failure or unstable performance.

DOM and Feature Support

Compatibility also includes feature recognition:

• DOM data visibility in switch OS

• Alarm and threshold reporting

• Proper link status detection

Lack of DOM support may not break the link, but it limits monitoring and troubleshooting capabilities.

Best Practices to Avoid Compatibility Issues

• Confirm switch model and OS version before purchasing

• Choose pre-coded, vendor-compatible modules

• Avoid “generic” optics with unclear compatibility claims

• Test modules in production-like conditions before full rollout

🎯 In practice, a properly coded third-party single mode 10G SFP+ module offers the same compatibility and performance as OEM optics—without the OEM price premium. For buyers, compatibility assurance is not a technical detail; it is a critical purchasing criterion that directly impacts deployment success and operational stability.

5️⃣ Single Mode vs Multimode 10G SFP+: Which One Should You Buy?

The choice between single mode and multimode 10G SFP+ modules depends on distance, existing fiber infrastructure, and long-term network planning—not just upfront module cost. Making the wrong choice can lead to higher upgrade costs or limited scalability.

Key Differences at a Glance

When You Should Choose a Single Mode 10G SFP+ Module

Single mode is the better choice when distance, flexibility, and long-term value matter.

Choose single mode if:

• Your link distance exceeds 300–400 meters

• You are connecting buildings or campus networks

• Future network expansion is likely

• You want to standardize on one fiber type across sites

Although single mode modules may cost more initially, they often reduce total cost of ownership by eliminating the need for future fiber upgrades.

When Multimode 10G SFP+ Still Makes Sense

Multimode remains a practical option for very short-distance deployments.

Choose multimode if:

• Connections are confined within a data center rack or room

• You already have OM3 or OM4 fiber installed

• Distance will never exceed a few hundred meters

• Lowest upfront cost is the top priority

In these scenarios, multimode 10G SFP+ modules offer simplicity and cost efficiency.

Cost vs Scalability: A Practical Buying Perspective

Many buyers focus only on module price, but fiber infrastructure often drives long-term cost.

• Multimode fiber becomes expensive and restrictive beyond short distances

• Single mode fiber supports higher speeds and longer reach with the same cabling

• Upgrading from multimode to single mode later can be disruptive and costly

If there is any uncertainty about future distance requirements, single mode is usually the safer investment.

Final Recommendation

• Choose single mode 10G SFP+ modules for most enterprise, campus, and service provider networks

• Choose multimode 10G SFP+ modules only for short, well-defined, in-rack connections

In transactional terms, single mode 10G SFP+ modules deliver greater flexibility, stronger future-proofing, and better overall return on investment for the majority of real-world deployments.

6️⃣ Pricing Guide for Single Mode 10G SFP+ Modules

Understanding pricing differences is essential when purchasing single mode 10G SFP+ modules, because cost varies based on distance support, vendor compatibility, temperature rating, and brand. This guide breaks down the key pricing factors and typical ranges so you can make a cost-efficient choice without sacrificing performance.

Typical Price Ranges by Module Type

Note: These ranges represent typical market prices as of 2026. Actual prices may vary depending on vendor, certification, and volume purchases.

What Drives Pricing Differences?

Choose industrial models only if your environment truly demands extended temperature tolerance.

4. DOM and Monitoring Features

Modules with Digital Optical Monitoring (DOM) support allow real-time insight into optical performance.

• DOM support: slight price premium (but high operational value)

• No DOM: lower price but limited remote diagnostics

In managed networks and data centers, DOM is generally worth the extra cost.

Price vs Value: Making the Smart Purchase

Cost alone should never be the only factor in your decision. Here’s how to align price with real value:

• Match distance needs: Over-spec’ing increases cost without performance benefit

• Choose compatible coding: Saves time and prevents deployment issues

• Confirm DOM support if required: Especially in enterprise environments

• Balance temperature needs: Only pay for industrial grade when necessary

Quick Buying Tips

• For most enterprise links under 10km: 10GBASE-LR modules with DOM support are the best value

• For metro or inter-building links: ER modules strike a good balance between reach and cost

• For service provider or backbone: ZR modules are necessary, but choose carefully to avoid overpaying

🎯 In summary, a well-planned purchasing strategy focused on real network requirements—rather than list price alone—will save money and ensure a future-proof single mode 10G SFP+ deployment.
