## Long description

The BlueOptics QSFP28-100G-CWDM4-PC-BO is a 100G fiber optic transceiver module with a QSFP28 interface and a metal housing designed for high-speed single-mode fiber links. Supporting a maximum data transfer rate of 100000 Mbit/s and featuring an LC Duplex optical connection with CWDM multiplexing, this compact module (weight 0.04 kg) is intended for use in data centers and high-performance network equipment where reliable 100G optical links are required.
Advantages
The transceiver combines a QSFP28 form factor with 100GBASE-CWDM4 optical transmission, providing a standardized interface and robust metal construction for durability. Its support for CWDM on both transmitter and receiver channels enables efficient wavelength-multiplexed single-mode transmission, and the lightweight design simplifies hot-swap installation in compatible ports. The module includes digital diagnostics monitoring capabilities for real-time information on supply voltage, laser bias current, transmit power, receive power and temperature when the host hardware supports DDM/DOM.
Suitable for
100G Ethernet uplinks in data center switches and routers
High-speed links between storage systems and servers
Carrier and metro networks requiring CWDM single-mode links up to a few kilometers
Environments needing digital diagnostics for optical link monitoring

How to use
Install the BlueOptics QSFP28-100G-CWDM4-PC-BO into a QSFP28-compatible port on your switch, router or other network appliance while the system is powered according to the host vendor's hot-swap guidelines. Connect LC Duplex single-mode fiber patch cords matched to CWDM channels and ensure proper patch panel routing or direct connection to the remote transceiver. Verify link status and, if available, read diagnostic parameters through the host management interface to confirm optical power and temperature are within acceptable ranges.
Usage recommendations
To achieve optimal range and signal quality, use single-mode LC Duplex patch cords specified for CWDM wavelengths and follow the switch or router manufacturer’s compatibility list. Confirm that the host device supports DDM/DOM if remote monitoring is required. Observe standard electrostatic discharge (ESD) precautions during handling and keep dust caps on unused fiber connectors to prevent contamination.
