Kuituvalolähetin-vastaanotinmoduuli BlueOptics JSH-21S3AB3-BO 550 m

The BlueOptics JSH-21S3AB3-BO is a single‑port SFP fiber optic transceiver module designed for short‑range multimode fiber links with a maximum transfer distance of 550 m. The module supports 1000Base‑SX data rates and uses an LC duplex connector. Its aluminium housing and compact SFP form factor allow installation in switches, routers and other networking equipment that accept MSA‑compliant SFP modules.

Advantages

This SFP transceiver provides gigabit optical connectivity over multimode fiber with an industry‑standard LC duplex interface and an aluminium enclosure that keeps the module lightweight (approx. 20 g). It is built to MSA specifications for form factor and electrical/optical compatibility and includes transmitter and receiver sections operating at 850 nm to support common short‑reach applications. The compact SFP format and standardized interface simplify replacement and upgrades in compatible network hardware.

How to use

Insert the SFP transceiver into a compatible SFP slot of your network device until it latches. Connect LC duplex multimode fiber patch cords to the module, observing transmit (Tx) and receive (Rx) orientation. Verify that the host equipment supports 1000Base‑SX SFP transceivers and, if available, enable or verify Digital Diagnostics Monitoring (DDM/DOM) support in the device to access real‑time module parameters. After connection, check link LEDs and device diagnostics to confirm a stable optical link.

Recommendations

For optimal performance, use multimode fiber and LC duplex patch cords rated for 850 nm, ensure clean connector endfaces before mating, and follow the host device vendor guidance on supported third‑party SFP modules. If remote monitoring is required, confirm the host supports DDM/DOM to read supply voltage, temperature, laser bias, and optical power values.
