Fiber optic transceiver module BlueOptics JL855A-BO SFP28 LC Aluminium

The BlueOptics JL855A-BO SFP28 LC Aluminium is a fiber optic transceiver module designed for 25G high-speed optical links. It follows MSA SFP28 form-factor standards and uses an LC duplex connector for single-mode fiber transmission. The module is housed in an aluminium enclosure and weighs approximately 20 g, providing a compact, industry-compatible solution for equipment that supports 25GBASE-LR optical interfaces.

Advantages

This SFP28 transceiver supports 25G data rates over single-mode fiber and is compatible with devices that accept SFP28 LC modules. The aluminium housing offers mechanical robustness and thermal dissipation while keeping weight low. The module is built to MSA standards to ensure interoperability with major networking platforms and supports digital diagnostics (DDM/DOM) for real-time monitoring of operational parameters such as supply voltage, transmit/receive power and temperature when the host hardware supports this feature.

How to use

Install the BlueOptics JL855A-BO into an SFP28-compatible port on your switch, router or server following the host device manufacturer’s insertion and handling guidelines. Connect an LC duplex single-mode patch cable to the module and to the remote transceiver or patch panel, ensuring correct transmit/receive orientation. Verify link status and, if available, use the host interface to read digital diagnostic parameters to confirm proper operation. Handle the module with ESD precautions and keep dust caps on unused connectors.

Recommendations

For optimal performance, pair the module with single-mode LC patch cords and compatible SFP28 ports that explicitly support 25GBASE-LR transceivers. Ensure host firmware allows DDM/DOM access if monitoring is required. Store and operate the module within the manufacturer-recommended temperature and humidity ranges specified by your equipment vendor.
