## Summary description

SFP28 transceiver BlueOptics BO04Q27640DIN is a 25GBASE-BX-U optical module for single-fiber, bi-directional 25 Gbps links with a transmission reach up to 40 km. Designed for data center and carrier networks, it enables high-speed uplinks and long-distance connections between switches, routers and DWDM systems. Suitable for replacing or upgrading SFP28 ports where single-fiber BX operation is required.

## Long description

The BlueOptics BO04Q27640DIN SFP28 transceiver is a 25GBASE-BX-U optical module engineered for single-fiber, bi-directional 25 Gbps links with a transmission reach up to 40 km. Designed for data center and carrier network environments, this compact SFP28 form-factor module provides a straightforward solution for upgrading or replacing SFP28 ports where single-fiber BX operation and long-distance connectivity are required between switches, routers and DWDM systems.
Advantages
This SFP28 transceiver supports full-rate 25 Gbps operation over a single optical fiber using bi-directional (BX) technology, reducing fiber count and simplifying cabling infrastructure. Its 40 km reach enables long-distance uplinks without intermediate amplification in many networks. The module follows industry-standard SFP28 electrical and mechanical specifications for plug-and-play compatibility with compatible host devices and supports reliable transmission suitable for high-density data center and carrier deployments.
Suitable for
 25 Gbps uplinks between switches and aggregation devices
 Long-distance single-fiber connections in campus and metro networks
 Integration with DWDM systems where BX single-fiber modules are required
 Replacing or upgrading SFP28 ports to enable bi-directional fiber links
Key specifications
 Form factor: SFP28, small form-factor pluggable
 Data rate: 25 Gbps
 Optical interface: Bi-directional single-fiber (BX)
 Maximum reach: up to 40 km (single-mode fiber)
 Wavelength: designed for single-fiber TX/RX pair (BX operation)
 Compatible applications: data center uplinks, carrier and metro networks, DWDM integration
 Power and thermal: conforms to SFP28 power and heat profiles for standard hot-pluggable operation
How to use
Insert the SFP28 transceiver into a compatible SFP28 port on a switch, router or media converter with the module latched securely. Connect a single-mode fiber with the appropriate single-fiber patch cords and ensure TX/RX orientation matches the remote BX module. Allow the host device to recognize the module and establish a 25 Gbps link; verify link status and optical parameters via the host management interface. For DWDM environments, ensure channel assignment and wavelength planning match the module pairing at both ends.
Usage recommendations
Use certified single-mode fiber and clean connectors to maintain signal integrity; follow the host vendor compatibility list to confirm support for SFP28 BX modules. Avoid bending or stressing fiber near the connector, monitor temperature and power levels within the host device’s specified ranges, and document TX/RX wavelength pairing when deploying multiple single-fiber links.
