What are Optical Transceivers?
An optical transceiver is a hot-swappable module that converts electrical signals to optical signals (and back) for fiber links between switches, routers, and servers. LINK-PP supplies MSA-compliant modules from 1G to 800G for data centers, enterprise, and telecom networks.
To evaluate modules correctly, start with definition, network role, and commercial value:
- Core definition: A transceiver combines transmitter and receiver optics in one housing, typically using VCSEL, DFB, or EML lasers with matching photodiode receivers.
- Role in networking: At the physical layer, the module sets achievable data rate and reach for each fiber port.
- Commercial value: Qualified optics reduce downtime and total cost of ownership. LINK-PP focuses on tested compatibility, stable supply, and project-ready pricing.
Types of Optical Transceivers
Form factor, data rate, fiber mode, and reach determine which module fits a given port. Use the table below to map common LINK-PP product families, then open the matching category for SKUs and datasheets.
| Form Factor | Supported Data Rates | Fiber Mode | Typical Transmission Distance |
|---|---|---|---|
| SFP | 1G | MMF & SMF | 550m (MMF), up to 160km (SMF) |
| SFP+ | 10G | MMF & SMF | 300m (MMF), up to 120km (SMF) |
| SFP28 | 25G | MMF & SMF | 100m (MMF), up to 40km (SMF) |
| QSFP+ | 40G | MMF & SMF | 300m (MMF), up to 100km (SMF) |
| QSFP28 | 100G | MMF & SMF | 100m (MMF), up to 80km (SMF) |
| QSFP56 | 200G | MMF & SMF | 100m (MMF), up to 10km (SMF) |
| QSFP-DD | 400G–800G | MMF & SMF | 100m (MMF), up to 80km (SMF) |
| OSFP | 400G–800G+ | MMF & SMF | 100m (MMF), up to 10km (SMF) |
Distances are typical MSA/IEEE ranges and vary by wavelength, fiber grade, and coding. Confirm the exact part number datasheet before deployment.
For denser fiber plants, LINK-PP also supplies specialized optics:
- WDM transceivers (CWDM / DWDM): multiplex multiple wavelengths on one fiber pair to raise capacity without new cable plant.
- BiDi transceivers: send and receive on one fiber strand using two wavelengths, reducing fiber count.
- Tunable DWDM modules: adjust wavelength in the field to simplify sparing and wavelength planning.
How to Choose the Right Optical Transceiver
Use this checklist before ordering, especially for mixed-vendor switches and long-reach links:
- Data rate: Match the host port speed (10G, 25G, 100G, 400G, 800G, etc.).
- Reach: SR for short MMF runs, LR for ~10km SMF, ER/ZR for extended / long-haul links.
- Form factor fit: Confirm cage and connector type (SFP28 vs QSFP28 vs QSFP-DD/OSFP).
- OEM coding: Specify platform coding (Cisco, Juniper, Arista, HPE, and others) so EEPROM identity is accepted.
- Temperature class: COM (0°C to 70°C) for climate-controlled rooms; IND (−40°C to 85°C) for outdoor or harsh sites.
Applications
- Data centers & cloud: ToR / spine-leaf interconnects with 100G–800G optics for high-density traffic.
- Enterprise & campus: Aggregation uplinks, SAN, and building backbone links that need stable uptime.
- Telecom & 5G/6G: Fronthaul, midhaul, and backhaul paths that often need industrial temperature and BiDi/WDM options.
- ISP / FTTH: PON and access optics for broadband handoff to homes and businesses.
FAQ
Common purchasing questions from B2B buyers:
Are LINK-PP transceivers compatible with major OEM switches?
Yes. Modules are coded and sample-tested for plug-and-play use on mainstream OEM platforms. Share your switch model when requesting a quote so we can confirm coding.
Do you offer wholesale or project pricing?
Yes. Volume and project pricing are available for qualified B2B orders. Contact sales with quantity, target OEM coding, and delivery window.
Can I request samples before a bulk order?
Yes. Sample units can be arranged for lab validation before larger releases.
What about stock and lead time?
Common SKUs ship from stock when available. Custom coding or large builds follow agreed production lead times.
Do you support OEM/ODM customization?
Yes. Options include label branding, EEPROM coding, and packaging tailored to your channel model.
