Modulo transceiver SFP28 BlueOptics SFP28-25G-ER-CH-BO 25000 Mbit/s 1310 nm

The BlueOptics SFP28-25G-ER-CH-BO is a single‑mode fiber optic SFP28 transceiver designed for 25 Gbit/s links over distances up to 40 km. It transmits and receives at a wavelength of 1310 nm, fits SFP28 ports and comes in a compact metal housing with a 3.3 V supply. The module is RoHS compliant, weighs approximately 2 g and uses an LC duplex optical interface to connect to single‑mode fiber cabling.

Advantages

This SFP28 transceiver provides high‑speed 25G performance with long‑reach capability up to 40 km, while the metal enclosure offers mechanical robustness and thermal stability. Compatibility with standard SFP28 interfaces and adherence to MSA form‑factor conventions enable straightforward integration into switches, routers and other 25G capable equipment. Low weight and a single 3.3 V supply simplify handling and installation.

Suitable for

• Long‑reach 25G Ethernet connections over single‑mode fiber
• Inter‑rack or campus backbone links up to 40 km
• Integration into switches, routers, storage systems and high‑speed network appliances with SFP28 ports
• Environments requiring RoHS‑compliant optical transceivers

How to use

Install the module into any compatible SFP28‑rated port following the host device manufacturer's hot‑swap and insertion guidelines. Connect LC duplex single‑mode fiber patch cords to the module, observing correct Tx/Rx orientation. Configure the host interface for 25G operation as required by your network equipment; the module will operate at 25 Gbit/s and 1310 nm wavelength once the link and transceiver are recognized. Ensure the host device supports the SFP28 MSA form factor and provides a 3.3 V supply on the transceiver socket.

Recommendations

To maintain link quality and module longevity, use single‑mode OS2 fiber and low‑loss LC patch cords, avoid sharp bends and excessive connector contamination, and verify that the host device supports DDM/DOM monitoring if remote diagnostics are required. Follow ESD precautions during handling and confirm firmware or compatibility notes from the equipment vendor when deploying in multi‑vendor environments.
