## Summary description

The BlueOptics QSFP28-100G-CWDM-BO is a fiber optic network transceiver module designed for high-speed data transfer at 100000 Mbit/s. It features a QSFP28 interface and is lightweight at only 4 g. Ideal for data centers and high-performance computing environments.

## Long description

The BlueOptics QSFP28-100G-CWDM-BO is a compact fiber optic network transceiver module designed for 100000 Mbit/s (100 Gbit/s) data transfer. It uses a QSFP28 interface and LC Duplex connector, supports single-mode fiber transmission with CWDM technology for parallel transmit/receive channels, and is supplied in a lightweight silver housing of approximately 4 g. The module is intended for integration into networking equipment that accepts QSFP28 form-factor transceivers and is suitable for short to medium single-mode fiber links where 100GBASE-CWDM4-level performance is required.
Advantages
The transceiver provides a standardized QSFP28 interface compatible with systems that accept 100GBASE-CWDM4 modules, enabling 100 Gbit/s Ethernet and similar high-speed protocols. Its single-mode fiber design with CWDM allows simultaneous transmit and receive channels via LC Duplex connectors, while the compact, lightweight metal housing contributes to dense port deployments. The module includes support for digital diagnostic monitoring (DDM/DOM) enabling remote real-time monitoring of parameters such as supply voltage, laser bias current, optical transmit and receive power, and temperature when used in compatible host hardware.
Suitable for
100 Gbit/s Ethernet links over single-mode fiber using CWDM
High-performance data center uplinks and switch interconnects
Storage area networks and Fibre Channel over Ethernet at 100G
Network equipment replacement or upgrades that accept QSFP28 transceivers
Key specifications
Interface type: QSFP28
Maximum data transfer rate: 100000 Mbit/s (100 Gbit/s)
Connector: LC Duplex (single-mode fiber)
Technology: CWDM (coarse wavelength division multiplexing)
Form factor: QSFP28 transceiver module
Weight: approximately 0.004 kg
Housing colour: silver
Support for Digital Diagnostic Monitoring (DDM/DOM) according to MSA SFF-8472 (host support required)
Typical application range: up to around 2 km over single-mode fiber (protocol dependent)
How to use
Install the BlueOptics QSFP28-100G-CWDM-BO into a QSFP28-compatible port on a switch, router, storage system or other networking device following the host vendor’s hot-swap and ESD handling procedures. Use LC Duplex single-mode fiber patch cords and ensure correct transmit/receive orientation. If monitoring is required, verify that the host hardware supports DDM/DOM to access real-time diagnostic parameters. After insertion, confirm link negotiation and that the device recognizes the transceiver and configures the interface for 100G operation according to the host system’s configuration tools.
Usage recommendations
To achieve reliable 100G links, use quality single-mode fiber and compatible LC patch cords, keep connectors clean, and follow the host equipment manufacturer’s compatibility list. Use DDM/DOM data for proactive monitoring and verify fiber link loss and polarity during installation. For distance and compatibility requirements, consult the system documentation to ensure the CWDM variant meets the intended link budget and protocol support.
