## Summary description

CBO QSFP-100G-CWDM4-DE-BO is a QSFP form-factor network transceiver module supporting 100 Gbit/s data rate with CWDM4 multiplexing. Designed for high-speed optical links, it enables aggregation and backbone connections in data centers and carrier networks. Use it for 100G Ethernet or compatible DWDM/CWDM systems to extend fiber links and simplify port upgrades.

## Long description

CBO QSFP-100G-CWDM4-DE-BO QSFP 100G CWDM4 is a QSFP form-factor network transceiver module designed for 100 Gbit/s optical links using CWDM4 multiplexing. The module supports short to medium reach fiber connections typically used in data center aggregation, spine-leaf architectures and carrier backbone links. It provides a compact hot-pluggable interface for 100G Ethernet and other compatible 100G optical transport systems, enabling upgrades of switch and router ports without replacing existing chassis or line cards.
Advantages
The transceiver offers a standardized QSFP form factor and hot-pluggable operation, simplifying installation and maintenance. CWDM4 multiplexing reduces fiber count compared with parallel optics while maintaining cost-effective reach for aggregation and metro links. The module is designed for interoperability with common 100G Ethernet equipment and supports fiber link extension without major infrastructure changes.
Suitable for
 100G Ethernet connections in data center aggregation and spine layers
 Carrier and metro backbone links using CWDM4 wavelengths
 Upgrading SFP28/SFP+ infrastructure to consolidated 100G ports
 Short to medium reach multimode/single-mode fiber runs in campus networks
Key specifications
 Form factor: QSFP (Quad Small Form-factor Pluggable)
 Data rate: 100 Gbit/s aggregate
 Optical multiplexing: CWDM4
 Interface: optical fiber (single-mode) compatible with CWDM4 transceivers
 Hot-pluggable: yes
 Typical use: short to medium reach optical links for aggregation and backbone
How to use
Install the module into a compatible QSFP slot on a switch or router while the chassis is powered on, ensuring the transceiver is fully seated and latched. Connect the single-mode fiber patch cable with the matching CWDM4-compatible connector type. Verify link status and module recognition in the host device management interface and configure the port for 100G operation according to network requirements. Follow vendor guidelines for handling optical transceivers to avoid contamination of fiber end faces and electrostatic damage.
Usage recommendations
Use certified single-mode fiber and CWDM4-compatible patching infrastructure to achieve specified performance. Clean fiber connectors before mating and verify power budgets and link budgets for planned distances. If interoperability issues occur, check host device firmware and transceiver compatibility matrices.
