Fiber optic transceiver CBO FN-TRAN-QSFP28-CWDM4-BO 100000 Mbit/s QSFP28 CWDM4

CBO FN-TRAN-QSFP28-CWDM4-BO is a QSFP28 fiber optic transceiver that supports 100000 Mbit/s and uses CWDM4 technology. It is designed for high-density 100G Ethernet and data center links, providing four-channel coarse wavelength division multiplexing over single-mode fiber in a compact, hot-pluggable QSFP28 form factor. The module targets applications such as 100G uplinks, spine-leaf interconnects and long-distance server aggregation where space-efficient 4-channel optics are required.

Advantages

The transceiver combines 100G throughput with CWDM4 multiplexing to enable higher port density and simplified fiber cabling. Its QSFP28 form factor enables hot-pluggable installation in compatible switches and routers, reducing maintenance downtime. The module supports single-mode fiber transmission for longer reach compared with multimode optics, while maintaining a compact 4-channel solution for aggregated links.

Suitable for

• 100G uplink connections between switches and routers
• Spine-leaf interconnects in data center architectures
• Long-distance server aggregation over single-mode fiber
• High-density switching environments requiring compact QSFP28 optics

Key specifications

• Data rate: 100000 Mbit/s (100G)
• Form factor: QSFP28, hot-pluggable
• Optical technology: CWDM4 (four-channel coarse wavelength division multiplexing)
• Fiber type: single-mode fiber (SMF)
• Application: 4-channel 100G links for data center and metro aggregation

How to use

Install the QSFP28 transceiver into a compatible QSFP28 port on a switch, router or transceiver cage following the host equipment manufacturer’s hot-plug procedure. Connect single-mode fiber cables to the module’s optical interface, ensuring correct polarity and clean connectors. Verify link status and speed on the host device and monitor optical levels where available. Remove the module by following the reverse of the insertion procedure when required.

Recommendations

Use certified single-mode fiber and maintain connector cleanliness to ensure optimal signal quality. Confirm compatibility with the host equipment and maintain firmware or hardware compatibility lists where applicable. For long links, verify optical budget and use appropriate fiber cabling and patch panels.
