Compatible SFP Transceiver

The STARTECH JD119BST is a hot-swappable SFP transceiver built for 1000BASE-LX Gigabit Ethernet links. It provides 100 percent compatibility with HP JD119B equipment and meets MSA industry standards for use in enterprise switches and routers.

Direct Replacement for HP JD119B

This module replaces an HP JD119B transceiver without configuration changes. The jump is worth it when a network needs a guaranteed compatible spare that delivers identical 1.25 Gbps performance over single-mode fiber at 1310 nm wavelength.

Single-Mode LC Duplex Integration

The transceiver fits any SFP slot accepting LC duplex connectors and operates from 0 to 70 degrees Celsius. It consumes less than one watt, supports Digital Diagnostics Monitoring, and frees budget by avoiding OEM pricing while maintaining 10 km reach.

Questions about this item

Does the SFP module use an LC duplex connector so I know which patch cord to order?

Yes, the transceiver has a single LC duplex female port for single-mode fiber.

Is the module hot-swappable or must I power down the switch first?

It is hot-swappable, so you can insert or remove it while the switch is running.

Will I need to clean or replace the optical interfaces over time?

Clean the LC ferrules with a lint-free wipe and isopropyl alcohol whenever you disconnect cables; the module itself has no user-replaceable parts.
