Cisco Systems, Inc.

Cisco 10/25GBASE-LR SFP28 Transceiver SMF 10km

SKU CH-Z2MG-TSNAG

Dual-rate SFP28 transceiver delivers 10 Gbps or 25 Gbps over 10 km single-mode fibre with LC duplex connectors

  • Device TypeTransceiver
  • Supports 10 km links on standard G.652 single-mode fiber
  • Dual-rate 10 Gbps and 25 Gbps Ethernet in one module
  • SFP28 form factor with LC duplex optical connector
  • Requires host RS-FEC for reliable 25 Gbps operation
  • Optimized for data networking and optical transport networks

10/25GBASE-LR SFP28 Transceiver

This Cisco transceiver provides a 10-kilometre reach on standard single-mode G.652 fibre at both 10G and 25G speeds. It uses an LC/PC duplex connector and the SFP28 form factor for data networking and optical network applications.

Host port RS-FEC requirement

Verify that the host equipment ports support RS-FEC before ordering, as this module requires it for 25G operation. Ensure the existing fibre infrastructure uses single-mode G.652 cable with LC/PC duplex patching.

Build integration

The module plugs directly into an SFP28 cage on a switch or router, freeing a high-density port for long-haul connectivity. It draws power from the host cage and operates across the standard temperature range without external cooling.

Highlights

  • Dual-rate 10 Gbps and 25 Gbps Ethernet in one module
  • SFP28 form factor with LC duplex optical connector
  • Requires host RS-FEC for reliable 25 Gbps operation
  • Optimized for data networking and optical transport networks

Questions about this item

Does the transceiver ship with the LC/PC duplex connector installed, or must I order patch cords separately?

The module has an integrated LC/PC duplex interface; you only need to supply compatible single-mode patch cords for the link.

Should I choose this 10/25GBASE-LR module over a shorter-reach variant for a 10 km run?

This module is rated for 10 km on G.652 single-mode fiber at both 10 G and 25 G speeds.

What does the 10 km figure mean when the module is running at 25 G in my switch?

At 25 G the link reaches 10 km on standard G.652 fiber provided the host ports have RS-FEC enabled.
