Description

The 25GBASE-ZR SFP28 transceiver is a long-reach optical module for single-mode fibre, built for 25G links of up to 80 km over standard G.652 fibre. It suits metro, campus and data centre interconnect runs, as well as deployments that need an industrial temperature range.

It operates at 1300 nm with a dual LC/PC connector, a transmit power of +2 to +7 dBm and a receive power range of -31 to -6 dBm. Maximum power consumption is 3 W, drawn from the host SFP28 port. The industrial temperature rating covers -40 to 85 C, which makes it suitable for harsh environments. This is the ZR 80 km industrial-temperature variant, so it is distinct from shorter-reach 25G optics. The host port must have RS-FEC enabled at 25G.

It is supported on Cisco switches with SFP28 ports, and platform support can be checked against the Cisco Transceiver Module Group Compatibility Matrix. Only PC or UPC LC patch cords are supported, and APC connectors are not.

Enquire with XS Network Tech for new or used pricing and availability.

FAQs

Q: Does the host port need any special configuration?
A: Yes. RS-FEC must be enabled on the host port at 25G for this module to operate.

Q: Which fibre and patch cords does it use?
A: It runs over standard G.652 single-mode fibre with dual LC connectors. Only PC or UPC patch cords are supported, and APC connectors are not.

Q: How much power does it draw?
A: Maximum power consumption is 3 W, drawn from the host SFP28 port, so no separate power supply is needed.

Q: Which switches support it?
A: It is supported on Cisco switches with SFP28 ports. Check the Cisco Transceiver Module Group Compatibility Matrix for the supported platforms.

Q: How does this differ from other 25G optics?
A: This is the ZR variant with an 80 km reach over single-mode fibre and an industrial -40 to 85 C operating range, so it suits much longer links than short-reach 25G modules.
