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

The Transceiver CBO QSFP28-100G-CWDM4 BO28L13602D is a QSFP28-form-factor 100G CWDM4 fiber optic module engineered for 100 Gigabit Ethernet links. It implements four CWDM channels over single‑mode fiber to support medium- to long-reach connections commonly required in data center uplinks and carrier network environments. The module fits QSFP28 ports and provides high-density 100G connectivity with interoperability for systems supporting CWDM4 optics.

Advantages

This QSFP28 100G CWDM4 transceiver offers compact form factor density and low power consumption suitable for high-density switch and router line cards. It supports four-wavelength coarse wavelength division multiplexing to carry 100G over a single pair of single-mode fibers, reducing fiber infrastructure requirements. The design focuses on signal integrity and compatibility with QSFP28 interfaces, enabling straightforward integration into existing network equipment and facilitating migration to higher bandwidth links.

How to use

Install the module into a compatible QSFP28 port on a switch, router, or optical transceiver module cage following the equipment vendor instructions. Connect the single‑mode fiber pair to the module’s optical interface using the appropriate duplex connector and ensure proper channel mapping and link configuration in the host system. Verify link status and optical diagnostics via the host management interface to confirm correct operation and monitor parameters such as optical power and temperature.

Recommendations

For reliable performance, use single‑mode fiber certified for CWDM applications and adhere to connector cleanliness best practices. Confirm compatibility with the host system’s QSFP28 port and firmware; consult system documentation for supported optics lists if required. Monitor link diagnostics after installation and plan for proper cooling and airflow in high-density deployments to maintain expected transceiver power and temperature operating ranges.
