## Summary description

BlueOptics BO28C3443640DIN is a single-fiber SFP fiber transceiver supporting 1000BASE-2BX-U links over a reach of up to 40 km. Designed for bi-directional (Bidi) transmission, it enables 1 Gbps Ethernet connectivity over a single optical fiber, simplifying fiber cabling and extending network reach for switches, media converters and routers in enterprise and telecom environments.

## Long description

BlueOptics BO28C3443640DIN is a single-fiber SFP transceiver engineered for 1000BASE-2BX-U (bi-directional) Ethernet links. The module transmits and receives data over a single optical fiber, supporting a link distance of up to 40 km and providing 1 Gbps full-duplex connectivity for compatible switches, routers and media converters. The compact SFP form factor and single-fiber design reduce cabling complexity, making it suitable for point-to-point fiber runs and extensions between buildings or network segments.
Advantages
This single-fiber transceiver reduces fiber infrastructure by using bi-directional optics, allowing separate transmit and receive wavelengths on the same fiber. Its SFP form factor fits standard SFP ports and hot-pluggable operation facilitates on-site upgrades without powering down equipment. The 40 km reach supports long-distance uplinks while maintaining gigabit throughput, and the module is compatible with common 1 Gbps networking equipment that accepts SFP modules for optical connectivity.
Suitable for
 Point-to-point fiber links between buildings or sites
 Upgrading copper links to 1 Gbps fiber connections
 Interfacing switches, routers and media converters in enterprise or telecom networks
 Long-reach uplinks and backbone segments up to 40 km
Key specifications
 Form factor: SFP (small form-factor pluggable)
 Standard: 1000BASE-2BX-U (1 Gbps bi-directional Ethernet)
 Optical interface: single-fiber bi-directional (Bidi)
 Maximum reach: up to 40 km over single-mode fiber
 Data rate: 1 Gbps
 Hot-pluggable: yes
How to use
Insert the SFP module into an empty SFP slot on a compatible switch, router or media converter until it clicks into place. Use a single-mode fiber cable with appropriate connectors and verify that the opposite end uses the complementary bi-directional wavelength module for proper TX/RX pairing. After physical installation, check link status LEDs on the equipment and ensure interface configuration (speed/duplex or auto-negotiation) matches 1 Gbps operation. For multi-vendor environments, confirm that the host accepts third-party SFP modules if required.
Usage recommendations
Install modules and connect fiber in a clean environment to avoid contamination. Use single-mode fiber for the full 40 km reach and ensure correct TX/RX pairing of bi-directional modules. Keep firmware and device compatibility information available when mixing vendors, and follow ESD precautions when handling the SFP module.
