10G Single-Mode SFP+ for Duplex LC Links

10GBASE-LRDuplex LC1310 nmDDM / DOM

Add a 10GBASE-LR single-mode optical interface to a compatible SFP+ host port. SFP-6121 uses duplex LC and a 1310 nm transmitter for routes up to 10 km, subject to the installed link budget. DDM/DOM gives a supported host visibility into optical status, while hot-plug support simplifies module replacement.

Compatibility — check before buying:
Confirm the switch/NIC supports this module and 10GBASE-LR. Match duplex LC single-mode cabling and the remote optics; a physical SFP+ slot alone does not prove compatibility. The 10 km reach depends on fibre and connector loss.

Key Features

 
Single-mode LR optical link
The 1310 nm duplex LC interface serves a compatible single-mode link. Check the 6.2 dB manufacturer budget against route losses.
 
Diagnostic visibility
DDM/DOM monitoring is available through a host that supports these diagnostics.
 
Hot-pluggable module
The MSA-compliant SFP+ module supports hot-plug installation. Follow the host instructions and protect exposed optical connectors.

What's in the Box

SFP-6121 transceiver

Frequently Asked Questions

Can I use multimode fibre?
This LR module is specified for single-mode fibre. Use the correct fibre and optical module at both ends.
Does it use one or two fibres?
It has a duplex LC interface for separate transmit and receive paths; it is not a single-fibre BiDi module.
Why check the host compatibility list?
Port form factor, supported optics and firmware policy all affect module acceptance and diagnostics.
Singular Expert Insight
Start with host support, then confirm LR optics at both ends and calculate fibre loss. Reach alone is not enough to select a transceiver. Ask Singular to check your host and optical link

Buyer’s Guide

Buy it if

Your supported 10G host needs a duplex LC single-mode LR link.

Skip it if

You need multimode SR, single-fibre BiDi or a different wavelength.

Also consider

A matching module for the remote end and an LC single-mode patch lead.
