Sklenené vlákno transceiver modul BlueOptics JSH-42S3AB3-BO 1250 Mbit/s SFP

The BlueOptics JSH-42S3AB3-BO 1250 Mbit/s SFP is a fiber optic small form-factor pluggable transceiver designed for multimode optical links. It supports a maximum data transfer rate of 1250 Mbit/s and uses an LC duplex interface to send and receive optical signals at 850 nm. The module is finished in silver, weighs approximately 20 g and complies with CE, RoHS and FCC standards, making it suitable for deployment in a wide range of network equipment that accepts SFP modules.

Advantages

This transceiver complies with MSA SFP form-factor guidelines and implements separate transmit and receive channels for reliable bidirectional multimode transmission. Components are selected to meet compatibility requirements with common hardware platforms, enabling interoperability with many switches, routers, storage systems and measurement devices. The module supports digital diagnostics (DDM/DOM) when used with compatible host hardware, allowing monitoring of supply voltage, laser current, optical transmit/receive power and temperature in real time. Designed for long service life and stable performance, it provides a compact, hot-pluggable solution for short-range optical connections.

How to use

Insert the BlueOptics SFP module into the SFP slot of a compatible switch, router or other networking device while the host is powered on or according to the device manufacturer’s guidelines for hot-pluggable modules. Connect LC duplex multimode fiber patch cables to the module’s LC ports, ensuring correct orientation of transmit and receive channels. Verify link status on the host device and, if available, enable or query DDM/DOM information to monitor operating parameters. When removing the module, follow the host equipment’s recommendations to avoid damage to the connector or fiber.

Recommendations

Use multimode OM1/OM2/OM3 fiber rated for 850 nm for optimal short-range performance. Ensure the host device firmware or drivers support third-party SFP modules and DDM/DOM if remote diagnostics are required. Handle the transceiver and fiber connectors with appropriate electrostatic discharge (ESD) precautions and keep protective caps on the LC connectors when the module is not in use to prevent contamination and maintain performance.
