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

The BlueOptics SFP28-25G-ER-AT-BO is a single‑mode fiber optic SFP28 transceiver module that supports 25 Gbit/s data transmission over distances up to 40 km. It operates at a 1310 nm wavelength, uses a metal housing for mechanical robustness and requires a 3.3 V supply. The module is RoHS compliant and provides an LC duplex optical interface compatible with MSA SFP28 form-factor deployments in switches, routers and storage systems that accept SFP28 optics.

Advantages

The module provides 25GBASE-ER performance in a compact SFP28 package, combining long reach capability with a low-profile metal housing for thermal stability and durability. Its single‑mode 1310 nm optics are designed to deliver reliable high bandwidth links up to 40 km, while the 3.3 V operation and standard SFP28 interface ensure broad hardware compatibility. RoHS compliance supports integration into regulated installations.

Suitable for

• Long‑reach 25G uplinks between data center buildings or campus sites
• Core and aggregation links in carrier or enterprise networks
• Interconnects for switches, routers and storage systems supporting SFP28
• High‑bandwidth low‑latency applications such as server-to-switch connections

How to use

Install the module into an SFP28-compatible port of a switch, router or other network device while the host equipment is powered according to the vendor's hot‑plug guidance. Connect LC duplex single‑mode patch cables to the TX and RX ports of the transceiver, paying attention to correct polarity. Configure the host interface for 25G operation if required by the device. Monitor link status and diagnostics through the host management system when available.

Recommendations

For optimal performance, use single‑mode fiber and quality LC duplex patch cables rated for long‑reach links, ensure clean connector endfaces before mating, and verify that the host hardware supports SFP28 optics and the 25GBASE‑ER profile. Allow adequate ventilation around the metal housing and follow manufacturer guidance for hot‑plugging and ESD precautions.
