Description

This dual-rate 10G/25G SFP28 optical transceiver supports 25GBASE-LR and 10GBASE-LR over single-mode fibre, with reach of up to 10 km on a 1310 nm wavelength. It uses an LC duplex connector and suits 25G server uplinks, leaf switch connections and inter-building links where multimode reach is insufficient. The MR-LR variant covers both 10G and 25G operation, giving flexibility in mixed-speed deployments.

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

FAQs

Q: What speeds does this SFP28 transceiver support?
A: It supports both 25GBASE-LR and 10GBASE-LR, so it can operate at 25G or 10G depending on the host port configuration.

Q: What type of fibre does it require?
A: It is designed for single-mode fibre with an LC duplex connector, operating at 1310 nm.

Q: What is the maximum reach?
A: The transceiver supports distances of up to 10 km over single-mode fibre.

Q: Can it be used in a standard SFP+ port?
A: This is an SFP28 form factor module intended for SFP28 ports. Use in SFP+ ports depends on host platform support, so check your switch or NIC documentation before deployment.

Q: How does the MR-LR variant differ from other Arista 25G optics?
A: The MR-LR variant uses 1310 nm single-mode optics with a 10 km reach, whereas short-reach 25G optics are typically multimode and limited to much shorter distances.
