SFP28 transceiver module BlueOptics SFP28-25G-ER-AL-BO 25000 Mbit/s 1310 nm

The BlueOptics SFP28-25G-ER-AL-BO is a single‑mode fiber optic SFP28 transceiver module designed for 25G high‑speed links. It supports a maximum data rate of 25,000 Mbit/s over distances up to 40 km using a 1310 nm wavelength. The module is housed in a metal case for mechanical durability, operates at a 3.3 V supply and complies with RoHS requirements. It is compatible with LC duplex single‑mode fiber connections and follows MSA SFP28 form‑factor guidelines for use in a wide range of networking hardware.

Advantages

The module provides a combination of high data throughput and long reach, enabling 25G connectivity across metropolitan and long‑haul single‑mode links. Its metal housing improves thermal conduction and mechanical protection, while the 1310 nm optical wavelength is suited for extended‑range single‑mode transmission. RoHS compliance ensures reduced hazardous substances in the device. The compact SFP28 interface supports hot‑swapping and broad interoperability with devices that accept standard SFP28 transceivers.

How to use

Install the BlueOptics SFP28-25G-ER-AL-BO into an available SFP28 port on your switch, router or other supported equipment while the host device is powered on or following the vendor’s hot‑swap guidance. Connect LC duplex single‑mode fiber patch cables to the transceiver, ensuring correct TX/RX orientation. Verify link status through the host device’s management interface and confirm the port negotiates at 25G where supported. If the host platform supports digital diagnostics (DDM/DOM), monitor optical power, temperature and supply voltage to validate operational parameters.

Usage recommendations

Use certified single‑mode LC duplex patch cables and maintain proper fiber cleanliness when connecting the transceiver to minimize insertion loss and ensure link reliability. Check compatibility with your hardware vendor’s supported transceiver list; enable or configure DDM/DOM monitoring if available to aid diagnostics. For long‑term stability, allow sufficient ventilation or airflow around the metal housing to assist thermal dissipation during sustained high‑speed operation.
