SFP transceiver BlueOptics TN-SFP-25G-ER-BO 25000 Mbit/s SFP28 1310 nm

The BlueOptics TN-SFP-25G-ER-BO is an SFP28 fiber-optic transceiver module designed for single-mode links with a nominal data rate of 25000 Mbit/s and an operating wavelength of 1310 nm. Housed in a durable metal casing and weighing approximately 2 g, this compact module provides an LC duplex interface for optical transmission and reception and requires a 3.3 V input supply. The module supports long-reach connections up to 40,000 m when used with compatible single-mode fiber and appropriate patching.

Advantages

The module delivers 25G performance in an SFP28 form factor, offering a compact and light solution for high-speed single-mode fiber links. Its metal housing contributes to mechanical durability and heat dissipation while the LC duplex connector enables simultaneous transmit and receive paths. The combination of 1310 nm operation and support for long distances makes it suitable for extended links where optical reach and low latency are required.

How to use

Install the transceiver into a compatible SFP28 slot on a switch, router, storage or other network device that supports 25G SFP28 modules. Connect a single-mode LC duplex fiber patch cable to the transceiver’s LC connector, ensuring correct transmit/receive orientation. Confirm that the host device supports the module and that the supply voltage is 3.3 V. After insertion and fiber connection, verify link status and speed via the host equipment’s management interface.

Recommendations

For optimal performance, use single-mode fiber and LC duplex patch cords rated for long-reach applications, verify host compatibility with 25G SFP28 modules, and ensure proper fiber polarity. If available, enable and monitor the module’s digital diagnostic (DDM/DOM) features on the host device to track supply voltage, temperature, and optical power metrics for proactive maintenance.
