Compatible Citrix SFP Transceiver

The STARTECH EW3Z0000587-ST is a Citrix EW3Z0000587 compatible SFP module built for 1 GbE fibre links. It targets network engineers who need a tested replacement for original Citrix optics in switches and routers.

Installation notes

The transceiver uses a standard LC duplex connector and hot-pluggable SFP form factor, so it inserts without tools into any compliant cage. The main risk is mismatched single-mode fibre patch cords or dirty end-faces, which will degrade the 1310 nm signal and cause link errors.

Distance and rate limits

The module is rated for 10 km over single-mode fibre at 1 Gbps, matching the 1000Base-LX reach specification. Beyond that distance the optical budget is exceeded and the link will not stay up, while higher-speed ports such as 10 GbE cannot use this transceiver.

Questions about this item

How do I confirm the EW3Z0000587-ST is operating correctly after installation?

Check the switch or router port status for a 1 Gbps link light and verify the 1000Base-LX connection remains stable over the single-mode fiber run up to 10 km.

What comes in the box with the EW3Z0000587-ST and what must I purchase separately?

The module itself is supplied; you will need to provide LC-terminated single-mode fiber patch cables and a compatible Citrix switch or router with an open SFP slot.

Which version of the STARTECH EW3Z0000587-ST should I choose for a 10 km single-mode link at 1310 nm?

This model is the 1310 nm LC variant rated for 10 km at 1 Gbps, matching the 1000Base-LX requirement for that distance and wavelength.
