SFP28 transceiver BlueOptics BO04Q33640DIN 25GBASE-BX-D single‑mode 25Gb/s 40 km

Compact SFP28 optical transceiver BlueOptics BO04Q33640DIN supports 25GBASE-BX-D single-mode transmission over a single fiber. It is designed for 25 Gb/s data rates and a maximum link distance of 40 km, providing a small-form-factor solution for long-reach uplinks, metro and access networks. The module is suitable for integration in switches, routers and optical equipment that require 25G single-fiber connectivity and supports duplex communication using separate wavelengths for transmitter and receiver functions.

Advantages

The SFP28 form factor offers high port density and low power consumption while delivering 25 Gb/s throughput on single-mode fiber. Its single-fiber bidirectional design reduces fiber cabling requirements and simplifies deployment in constrained fiber environments. The module is engineered for compatibility with standard 25GBASE-BX-D interfaces, providing predictable optical performance for distances up to 40 km. Compact dimensions make it easy to install into SFP28 slots of network devices where space and heat dissipation are limited.

Key specifications

How to use

Insert the SFP28 transceiver into an available SFP28 port on a compatible switch, router or media converter while the host device is powered on or off according to the host manual. Ensure the device supports 25GBASE-BX-D and single-fiber bidirectional optics. Connect the single fiber using the appropriate patch cord or fiber adapter; observe correct orientation for transmit and receive wavelengths. After insertion and fiber connection, check link status indicators on the host device and verify link parameters via management interfaces. Monitor optical power levels and error counters to confirm reliable operation.

Recommendations

Use single-mode patch cords and compatible splitters or adapters designed for bidirectional single-fiber optics. Verify host compatibility and firmware support for 25GBASE-BX-D before deployment. Keep fiber connectors clean and handle the module according to ESD precautions. For reliable long-reach links, confirm optical power budget and perform end-to-end testing after installation.
