Glasvezel-transceivermodule BlueOptics JSH-42L4DD1-BO 1250 Mbit/s LC

The BlueOptics JSH-42L4DD1-BO is a fiber optic SFP transceiver module designed for single-mode optical links with a maximum data transfer rate of 1250 Mbit/s. It uses an LC duplex interface in a compact silver enclosure and weighs approximately 20 g. The module follows MSA-compatible form factor conventions and is suitable for integration into network equipment that accepts 1000BASE-LX SFP modules. Certifications such as CE, RoHS and FCC indicate compliance with common safety and environmental standards.

Advantages

The transceiver supports 1000BASE-LX class single-mode operation at 1310 nm for both transmitter and receiver channels, enabling duplex optical communication over standard single-mode fiber. Its SFP form factor and LC connector ensure broad interoperability with switches, routers and storage hardware that support MSA-compliant SFP modules. The module's compact size and light weight simplify installation in dense equipment racks while certified production and component selection target reliable long-term operation.

How to use

Power down or follow hot-swap procedures recommended by your hardware vendor, then insert the BlueOptics SFP module into an available SFP slot until it latches. Connect LC duplex fiber patch cords observing transmit-to-receive alignment (TX to RX) and ensure appropriate fiber type (single-mode) is used. After insertion, verify link status through the host device management interface and confirm the module is recognized. If the host platform supports Digital Diagnostics Monitoring (DDM/DOM), enable or query the diagnostics to monitor operating parameters such as temperature, laser bias current and optical power.

Recommendations

Use high-quality single-mode LC patch cords and maintain clean connector endfaces to ensure optimal optical performance. Confirm compatibility with the target hardware's supported SFP modules and, if required, enable DDM/DOM support on the host device to take advantage of real-time diagnostics. Follow ESD precautions during handling and avoid bending fiber beyond its specified radius.
