## Summary description

The BlueOptics BO28C3443640D-BO is a fiber optic cSFP transceiver module designed for high-speed data transmission. It features an LC connector and is made of durable aluminium, weighing only 20 g. This module is suitable for various networking applications, providing reliable performance and ease of installation.

## Long description

The BlueOptics BO28C3443640D-BO cSFP LC Aluminium fiber optic transceiver is a compact module designed for single‑mode optical links. It supports 1000BASE‑2BX‑U transmission with a duplex LC connector and is constructed in an aluminium housing weighing approximately 20 g. The module integrates a 1490 nm transmitter and a 1310 nm receiver to enable simultaneous send/receive operation over separate fibers and is intended for use in equipment that supports MSA‑compliant cSFP transceivers.
Advantages
This cSFP transceiver provides a standardized mechanical and electrical fit that simplifies installation and replacement. The aluminium housing offers durable protection while keeping the module lightweight. Support for single‑mode fiber and the LC duplex interface enables long‑reach links up to typical distances for 1000BASE‑2BX‑U applications. Built‑in digital diagnostics (DDM/DOM, SFF‑8472 compliant) allows remote monitoring of supply voltage, laser current, optical transmit/receive power and temperature to assist with fault finding and maintenance.
Suitable for
 Optical uplinks between switches and routers in enterprise networks
 Long‑reach point‑to‑point links over single‑mode fiber
 Interconnection of storage systems and SAN components supporting gigabit optics
 Replacement or upgrade of MSA‑compliant cSFP transceivers in networking hardware

How to use
Insert the BlueOptics cSFP module into any compatible cSFP slot following the host device manufacturer’s hot‑plug guidelines. Connect LC duplex single‑mode patch cords to the transmitter and receiver ports according to the device labelling (Tx/Rx). Ensure the host device supports 1000BASE‑2BX‑U operation and, if required, enable DDM/DOM in the management interface to read real‑time diagnostic values. Perform standard link tests and verify optical power and link status through the host equipment.
Usage recommendations
Use high‑quality single‑mode patch cords and, where available, BlueOptics‑recommended cabling to achieve optimal range and signal integrity. Verify that the target hardware supports MSA‑compliant cSFP modules and the DDM/DOM feature if diagnostics are needed. Protect the transceiver from mechanical stress and contamination of the fibre endfaces during installation and maintenance.
