JNI CORP JSH-21S3AB3: genuine JDS Uniphase 1000BASE-SX SFP with DDM, 850nm multimode.

The JDSU JSH-21S3AB3 is a genuine JDS Uniphase (JDSU) SFP transceiver, a 2Gbps short-wavelength 850nm 1000BASE-SX module with digital diagnostic monitoring (DDM), from the same JSH-2xxxx family as the JDSU-tagged JSH-21L3AR3 catalogued alongside it in this range. It installs directly into a standard SFP cage on a compatible switch or router for a Gigabit Ethernet or 2Gb Fibre Channel link over multimode fibre, with the DDM feature giving real-time visibility of transmit/receive power and temperature for fault diagnosis. Transceivers of this generation remain in routine service, and genuine spares are a standard requirement for maintaining port capacity or restoring redundancy. Confirm the host platform’s supported-transceiver list before ordering. Tech-Star (UK-based, shipped worldwide) supplies optical transceivers to support ongoing network maintenance projects. Please contact our sales team for current stock and pricing.
