Fiber optic transceiver module BlueOptics JSH-12L1DD1-BO 1250 Mbit/s LC

The BlueOptics JSH-12L1DD1-BO is an SFP fiber optic transceiver module designed for single-mode optical links with an LC duplex interface. It supports a maximum data transfer rate of 1250 Mbit/s and is supplied in a compact silver housing weighing approximately 20 g. The module meets common regulatory standards (CE, RoHS, FCC) and is intended for use in networking equipment that accepts MSA-compatible SFP modules.

Advantages

The module combines a small form factor and a standardized LC connector to simplify installation in switches, routers and other networking devices. Its single-mode optical transmission supports link distances typical for 1.25 Gbit/s class transceivers while the low weight contributes to easy handling and reduced mechanical strain in dense assemblies. Compliance with CE, RoHS and FCC standards ensures regulatory conformity for most commercial deployments.

Suitable for

• 1.25 Gbit/s single-mode fiber links with LC connectors
• Upgrading or repairing switches, routers and storage interfaces that accept MSA SFP modules
• Data center and enterprise backbone connections where compact SFP modules are required
• Environments requiring RoHS- and CE-compliant optical transceivers

Key specifications

• Interface type: LC duplex
• Maximum data transfer rate: 1250 Mbit/s
• Optical medium: single-mode fiber (designed for single-mode optical transmission)
• Housing colour: silver
• Weight: 0.02 kg
• Regulatory compliance: CE, RoHS, FCC

How to use

Power down the host device if recommended by the equipment vendor, then insert the SFP module into an open SFP port with the LC connector face oriented toward the fiber patch cable. Secure the module according to the host device’s retention mechanism. Connect single-mode LC patch cords to the transmit and receive ports, ensuring correct polarity. After installation, verify link status in the host device management interface and confirm the module is recognized at the expected data rate. Follow the network equipment manufacturer’s instructions regarding hot-swap support and firmware compatibility when replacing or adding transceivers.

Usage recommendations

For reliable long-term operation, use single-mode LC patch cords of appropriate quality and confirm the host device supports MSA SFP modules at 1.25 Gbit/s. Verify that Digital Diagnostics (DDM/DOM) functions are supported by your hardware if real-time monitoring is required. Store and handle the transceiver in a dust-free environment and avoid exposing the optical ports to contaminants when not connected.
