## Long description

The BlueOptics 100G-CWDM4-QSFP2KM-BO is a compact fiber optic network transceiver module designed for high-speed data transmission in modern networks. Featuring a QSFP28 interface and a stated maximum data transfer rate of 27000 Mbit/s, this silver-coloured module supports dense, short-reach multi-channel links over single-mode fiber. The small form factor and a reported mean time between failures of 1,000,000 hours make it suitable for integration into network switches, routers and other telecommunications equipment where space efficiency and long-term reliability are required.
Advantages
The module's QSFP28 interface enables high-density port configurations and simplified installation into compatible cages and slots. Its compact dimensions and low weight contribute to efficient rack and chassis population without adding significant mass. The certified long MTBF supports continuous operation with reduced maintenance needs, while the silver housing provides standardized mechanical compatibility and heat dissipation properties for typical telecom environments.
Suitable for
 Short-reach 100G links in data center aggregation and spine networks
 High-density switch and router uplinks
 Carrier and enterprise fiber backbone segments
 Environments requiring compact modules with long operational life
Key specifications
 Interface type: QSFP28 compatible form factor
 Maximum data transfer rate: 27000 Mbit/s
 Optical type: CWDM4 multi-channel short-reach over single-mode fiber
 Typical deployment range: designed for up to 2 km class short-reach links (verify per system compatibility)
 Weight: 0.05 kg
 Product colour: Silver
 Reliability: mean time between failures approximately 1,000,000 hours
How to use
Install the transceiver into a compatible QSFP28 slot following the host equipment manufacturer's guidance. Ensure fiber connectors and patch cords are clean and match the CWDM4 channel plan for correct optical alignment. After physical insertion, verify link status and transceiver recognition through the host system's management interface and confirm negotiated speeds. Handle the module by its housing, avoid touching optical interfaces, and use protective caps when ports are not connected.
Usage recommendations
For reliable performance, use single-mode fiber cables and transceiver-compatible patch panels, maintain proper cable routing and bend radii, and operate the module within the ambient temperature and power specifications of the host equipment. Regularly inspect and clean fiber endfaces and confirm firmware or driver compatibility on active networking equipment to ensure stable 27000 Mbit/s operation.
