Transceiver CBO QSFP28-100G-CWDM4 BO28L13602D 100G CWDM4 fiber optic module

CBO QSFP28-100G-CWDM4 BO28L13602D is a QSFP28 fiber optic transceiver module that supports 100G CWDM4 transmission. It is designed for high-speed data links in data centers and enterprise networks, implementing four-channel coarse wavelength-division multiplexing to deliver 100 Gbps connectivity over single-mode fiber as defined by CWDM4 standards. The module is compact and hot-pluggable, intended for use in QSFP28 sockets to provide switch-to-switch, server uplink and aggregation links with a small form factor compatible with modern network equipment.

Advantages

The transceiver provides multi-channel CWDM4 operation that enables cost-effective 100G links using four wavelengths over a single duplex fiber pair, reducing fiber count compared to parallel solutions. Its QSFP28 form factor offers hot-pluggable installation and dense port-to-port deployment in racks and chassis. The module is interoperable with standard QSFP28 interfaces, allowing straightforward integration into existing network switches and servers that support 100G optics.

Suitable for

• High-speed switch-to-switch links in data center spine and leaf architectures
• Server uplinks requiring 100 Gbps bandwidth
• Aggregation links between access and distribution layers

Key specifications

• Optical interface: QSFP28 form factor
• Data rate: 100 Gbps aggregate using four CWDM channels
• Multiplexing: Coarse Wavelength-Division Multiplexing (CWDM4)
• Fiber type: single-mode fiber operation as specified by CWDM4
• Installation: hot-pluggable module for QSFP28 sockets

How to use

Insert the QSFP28-100G-CWDM4 module into a compatible QSFP28 port on a switch or server while the device is powered on or as directed by the host equipment manual. Connect the appropriate single-mode fiber patch cables and ensure that the fiber polarity and connector types match the port and transceiver requirements. Verify link status through the host device management interface and confirm that the port is configured for 100G operation and compatible transmission settings.

Recommendations

Use certified single-mode fiber and follow standard fiber handling procedures to avoid contamination and damage. Confirm optical power budgets and link distances against CWDM4 specifications before deployment, and perform end-to-end testing after installation to validate signal integrity and interoperability with existing equipment.
