## Summary description

The BlueOptics QSFP-100G-CWDM4-IT-BO is a fiber optic transceiver module designed for high-speed data transfer up to 100000 Mbit/s. It features a QSFP28 interface, operates at an input voltage of 3.3 V, and is housed in a durable metal casing. Weighing only 4 g, it is ideal for efficient networking solutions.

## Long description

The BlueOptics QSFP-100G-CWDM4-IT-BO is a QSFP28 fiber optic transceiver module designed for 100G high-speed optical links. Housed in a metal casing and weighing approximately 4 g, the module supports 100000 Mbit/s data rates and uses LC duplex connectors for single-mode fiber connections. It operates from a 3.3 V supply and implements CWDM4 wavelength multiplexing to transmit and receive over defined coarse wavelength channels, providing a compact solution for data center and carrier-class networking equipment.
Advantages
The transceiver conforms to QSFP28 mechanical and electrical MSA standards and is compatible with equipment that supports 100GBASE-CWDM4. Its compact metal housing and low weight allow dense port deployment. Built-in digital diagnostics (DDM/DOM) enable real-time monitoring of supply voltage, laser bias current, transmit power, receive power and temperature, which simplifies maintenance and troubleshooting. The CWDM4 design supports cost-effective 100G links over single-mode fiber for distances up to about 2 kilometers when used with appropriate cabling.
Suitable for
100G Ethernet and high-speed interconnects in data centers
Carrier and metro networks requiring CWDM4-based 100G links
Switches, routers and storage systems with QSFP28 ports supporting 100GBASE-CWDM4
Environments needing remote monitoring of optical link parameters via DDM/DOM
Key specifications
Interface type: QSFP28
Maximum data transfer rate: 100000 Mbit/s (100G)
Connector: LC duplex for single-mode fiber
Wavelength multiplexing: CWDM4
Supply voltage: 3.3 V
Housing: metal casing, silver colour
Typical reach: multimode use not applicable; single-mode operation up to approximately 2 km depending on link margin and cabling
Digital Diagnostics Monitoring (DDM/DOM) for voltage, bias current, optical power and temperature
Weight: approx. 0.004 kg
How to use
Insert the QSFP28 transceiver into a compatible QSFP28 port until it is fully seated and the module latch engages. Connect LC duplex single-mode fiber patch cords to the transmit and receive ports, observing correct duplex polarity. Verify that the host device supports 100GBASE-CWDM4 and that DDM/DOM is enabled if you require monitoring. After installation, check link status on the host equipment and review diagnostic values via the management interface to confirm proper operation.
Usage recommendations
Use single-mode fiber patch cords and adhere to recommended loss budgets for CWDM4 links. Avoid bending fibers beyond the specified radius and keep connectors clean to minimize optical loss. Confirm firmware and compatibility with the host device prior to deployment and use DDM/DOM information for proactive maintenance.
