Fiber optic transceiver module BlueOptics JSHR21S303910-BO 1250 Mbit/s SFP

The BlueOptics JSHR21S303910-BO fiber optic transceiver module is an SFP (Small Form-factor Pluggable) pluggable transceiver designed for 1000Base-SX multimode fiber networks with a maximum data transfer rate of 1250 Mbit/s. Housed in a silver metal case and weighing approximately 20 g, this SFP module uses LC duplex connectivity and is built to MSA-compatible mechanical and electrical standards. It supports simultaneous transmit and receive optical signals at 850 nm and is compliant with CE, RoHS and FCC regulations, providing a compact option for adding optical uplinks to switches, routers and other network equipment.

Advantages

The module offers reliable optical transmission over multimode fiber with an industry-standard LC duplex interface and compatibility with common hardware platforms. Its MSA-compatible design ensures physical interoperability with SFP slots, while integrated components and production testing aim to deliver consistent performance and extended service life. The module's compact SFP form factor simplifies installation and replacement in confined equipment racks.

Key specifications

How to use

Insert the transceiver into an SFP slot of a compatible switch, router or compatible network device until it latches. Connect LC duplex multimode fiber patch cables to the module's LC ports, observing correct transmit/receive orientation. Configure the host device port for 1000Base-SX operation if required by the device's management interface. For remote monitoring, enable the device's DDM/DOM support if the host platform provides access to digital diagnostic data.

Recommendations

Use high-quality multimode fiber patch cables and ensure clean LC connectors before mating to minimize insertion loss. Verify that the host device supports 1000Base-SX SFP modules and, if required, that digital diagnostics (DDM/DOM) are enabled on the platform to monitor optical power, temperature and supply voltage. Avoid bending fiber beyond specified minimum bend radius and handle the module by its housing to prevent damage to the optical interface.
