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

BlueOptics Transceiver CBO QSFP28-100G-CWDM4 BO28L13602D is a QSFP28 fiber optic module that supports 100G CWDM4 data transmission. The module integrates four coarse wavelength-division multiplexing (CWDM) channels in a compact QSFP28 form factor, enabling 100 Gigabit Ethernet links over multimode or single-mode fiber for short- to medium-range connections. It is designed for integration into data center switches, routers and high-density aggregation equipment where reliable 100G connectivity and simplified fiber management are required.

Advantages

The transceiver delivers 100G throughput using four CWDM lanes within a single QSFP28 package, reducing port density and cabling complexity. Its compact design supports hot-pluggable installation and interoperability with standard QSFP28 ports. The module provides stable optical performance for aggregated traffic, lowering the need for multiple parallel fibers while maintaining compatibility with standard 100 Gigabit Ethernet link budgets.

Suitable for

• 100 Gigabit Ethernet links in data centers
• High-density switch and router uplinks
• Enterprise core and aggregation networks
• Fiber backbone connections requiring CWDM multiplexing

Key specifications

• Form factor: QSFP28 (quad small form-factor pluggable)
• Data rate: 100 Gbps aggregate (4 × 25 Gbps lanes)
• Optical technology: CWDM4 (four CWDM channels)
• Transmission range: short- to medium-range links (designed for data center distances)
• Connector type: compliant with QSFP28 optical interfaces
• Operating conditions: designed for typical data center temperature and power envelopes

How to use

Install the QSFP28 module into a compatible QSFP28 port on a switch or router while the host device is powered on, following the host vendor's hot-plug handling procedures. Connect appropriate single-mode fiber with matching LC or MPO patching infrastructure as required for CWDM4 deployments, ensuring correct channel mapping and link polarity. Verify link status via the host device and monitor optical parameters through the transceiver management interface if available.

Recommendations

Use certified single-mode fiber and proper CWDM patching practices to ensure optimal performance. Confirm compatibility with the network equipment vendor's transceiver support list and maintain clean connector end faces. For reliable 100G operation, manage temperature and power within specified data center tolerances and use link diagnostics to detect degradation.
