The Brocade XBR-000139 is a 4Gb short-wavelength Fibre Channel optical transceiver designed for SAN environments. It supports up to 4.25 Gbit/sec operation, uses an 850 nm wavelength, and is identified by manufacturing part number 57-1000013-01.

It supports a data rate of 4.25 Gbit/sec. This makes it suitable for 4G Fibre Channel connectivity in Brocade SAN switches and related supported platforms.

The transceiver uses short-wavelength optics at 850 nm and supports multimode fiber. The listed maximum distance is up to 150 m at 4.25 Gbps, though some product listings may reference broader connectivity figures depending on fiber type and deployment conditions.

It uses a Duplex LC connector and is designed for MMF, or multimode fiber, cabling. This is standard for many short-wavelength Fibre Channel optical connections.

Yes. It supports Digital Optical Monitoring, which helps determine whether the module is operational, marginal, or failing. It also includes Brocade ClearLink Diagnostics for identifying physical link issues in supported SAN environments.
