QSFP Transceiver Module BlueOptics QSFP-100G-CWDM4-ET-BO 100000 Mbit/s

The BlueOptics QSFP-100G-CWDM4-ET-BO is a QSFP28 fiber optic transceiver module engineered for 100 Gbit/s optical data transmission over single-mode fiber. The module uses CWDM4 wavelength multiplexing with LC duplex connectors and is housed in a compact metal casing with a nominal weight of 4 g. It operates from a 3.3 V supply and is suitable for integration into network devices that accept QSFP28 transceivers and support the 100GBASE-CWDM4 transmission standard.

Advantages

This QSFP28 transceiver supports high-bandwidth links up to 100000 Mbit/s while remaining lightweight and mechanically robust thanks to its metal enclosure. The CWDM4 design enables four-channel coarse wavelength division multiplexing for efficient single-mode fiber use, and the LC duplex interface simplifies connection to standard fiber patch panels. The small form factor and compliance with MSA QSFP28 mechanical and electrical profiles make the module suitable for many third-party network platforms that accept compatible 100G modules.

How to use

Install the BlueOptics QSFP-100G-CWDM4-ET-BO into a compatible QSFP28 port on your switch, router or host adapter while the device is powered down or following the hardware vendor’s hot-swap guidelines. Connect LC duplex single-mode fiber patch cables to the module’s duplex LC interface, ensuring correct transmit/receive orientation. Verify that the host hardware supports 100GBASE-CWDM4 optics and enable or configure the interface according to your network equipment documentation. Monitor link status and diagnostics via the host device to confirm proper operation.

Recommendations

Ensure the target hardware supports DDM/DOM if you require real-time monitoring (voltage, temperature, laser bias and optical power). Use high-quality single-mode LC patch cords and follow vendor guidelines for ESD protection and insertion/removal procedures to preserve module lifetime and link reliability.
