Sklenené vlákno transceiver modul BlueOptics JSH-42S4AA3-BO 1250 Mbit/s SFP

The BlueOptics JSH-42S4AA3-BO is an SFP fiber optic transceiver module designed for 1000Base-SX multimode links with a maximum data transfer rate of 1250 Mbit/s. Housed in a compact silver enclosure and compliant with CE, RoHS and FCC, this SFP uses an LC Duplex interface and supports simultaneous transmit and receive operation at 850 nm. With a lightweight 20 g construction and MSA-compliant mechanical and electrical characteristics, it is suitable for insertion into a wide range of networking hardware that accepts standard SFP modules.

Advantages

The module follows MSA standards for mechanical compatibility and is manufactured using components from established suppliers to deliver stable optical performance and extended service life. It supports Digital Diagnostics Monitoring (DDM/DOM) when the host device also supports this feature, enabling real-time reporting of supply voltage, laser bias current, transmit/receive power and temperature. Low susceptibility to electromagnetic interference and multimode transmission characteristics make the transceiver suitable for reliable short-range fiber links.

How to use

Insert the BlueOptics SFP module into any compatible SFP slot on switches, routers, storage devices or other network equipment while the host device is powered down or supports hot-plug insertion. Terminate both ends of the multimode fiber with LC duplex connectors and verify polarity. If the host supports DDM/DOM, enable monitoring through the device management interface to view real-time diagnostic parameters. Ensure the transceiver and fiber type match the intended link distance and topology.

Recommendations

Use OM1/OM2/OM3 multimode fiber appropriate for 850 nm operation and limit connector contamination by cleaning LC connectors before mating. Verify host compatibility and enable DDM/DOM if required for monitoring. For best results, pair the transceiver with certified multimode patch cords and follow manufacturer guidance for insertion, removal and handling to avoid electrostatic or mechanical damage.
