What specific applications benefit most from an SFP+ 120km transceiver?

This SFP+ 120km module is highly optimized for ultra-long-haul telecommunications, remote data center interconnects, and regional campus networks where deploying intermediate optical repeaters is logistically impossible or cost-prohibitive.

Do I need to use an optical attenuator with this SFP+ 120km module?

Yes, because the SFP+ 120km optic utilizes a high-power laser designed for extreme distances, connecting two modules back-to-back or over short fiber runs requires an optical attenuator to prevent permanent receiver damage.

How does this module handle chromatic dispersion over 120km?

The transceiver employs a highly specialized 1550nm laser and advanced modulation techniques specifically engineered to mitigate chromatic dispersion, ensuring clean signal recovery at the far end of the SFP+ 120km link.

Is this SFP+ 120km module compatible with standard single-mode fiber?

Absolutely, this extended-reach optic is fully compatible with standard 9/125um single-mode fiber terminating in LC connectors, making it easy to integrate into existing long-haul cable plants.

Can I monitor the health of the SFP+ 120km link in real time?

Yes, the module features Digital Diagnostic Monitoring compliant with SFF-8472, allowing network administrators to track the exact transmit and receive optical power levels across the entire SFP+ 120km span.

Does this optic support OTN and CPRI protocols for our telecom base station backhaul, or just standard 10G Ethernet?

It is highly versatile. Besides being fully compliant with 10G Ethernet standards, it supports standard CPRI, eCPRI, and OTU2/OTU2e data rates, making it perfect for both enterprise LAN extensions and long-haul telecom base station applications.

Will this 10G 120km SFP+ work with our mix of Cisco and Arista datacenter switches?

Yes, these ultra-long-haul transceivers are strictly tested for OEM compatibility. They will plug and play seamlessly with Cisco, Arista, Juniper, Ubiquiti, and other major brands right out of the box without any vendor lock-in issues.

Can I use multimode fiber for a quick test in the lab, or is this strictly for single-mode?

This 1550nm transceiver is designed exclusively for Single Mode Fiber (SMF) with a Duplex LC connector. To prevent receiver saturation and hardware damage on short test runs, we strongly recommend using OS2 SMF cable along with appropriate optical attenuators (usually 10dB to 15dB for lab testing).

We are rolling out a state-wide ISP upgrade and need about 80 of these extended-reach modules. Do you offer bulk discounts?

Absolutely! For large-scale B2B procurements of our 10G SFP+ 120km transceivers, please contact our B2B sales team. We provide tiered volume pricing and dedicated procurement support for enterprise and ISP clients.

We plan to install these in unventilated outdoor telecom cabinets. Do you have an industrial wide-temperature version of this 120km optic?

This specific module is designed for standard commercial temperatures (0°C to 70°C). However, we do offer an industrial-grade version (-40°C to 85°C) for this exact 1550nm 120km spec. Please check our store or contact support directly for the industrial SKU.
