Transceiver CBO QSFP28-100G-CWDM4 BO28L13602D Fiber Optic 100G

The Transceiver CBO QSFP28-100G-CWDM4 BO28L13602D Fiber Optic 100G is a QSFP28 optical module designed for 100 Gigabit Ethernet and high-density interconnects. It implements CWDM4 wavelength multiplexing with four 25G lanes in a compact QSFP28 form factor. The module is intended for use in data center and carrier networks where hot-pluggable, space-efficient 100G fiber links are required.

Advantages

The module provides a compact QSFP28 footprint that supports four independent 25G channels aggregated to 100G, enabling high port density in switches and routers. CWDM4 wavelength multiplexing reduces fiber count and simplifies cabling for short- and medium-reach links. Hot-pluggable design allows for live installation and replacement without powering down systems. The transceiver is compatible with standard 100G Ethernet interfaces and is suitable for rack-scale and spine-leaf architectures.

Suitable for (tasks / use cases)

• 100G Ethernet links between switches and routers in data centers
• Interconnects in carrier access and metro networks requiring compact modules
• High-density aggregation ports in top-of-rack and leaf switches
• Upgrades from 40G to 100G where CWDM4 multiplexing is supported

Key specifications

• Form factor: QSFP28
• Data rate: 100 Gigabit Ethernet (4 x 25 Gbps lanes)
• Wavelengths: CWDM4 wavelength-multiplexed lanes
• Interface type: fiber-optic
• Connector: MPO/MTP compatible (multi-fiber parallel connector)
• Operation: hot-pluggable
• Typical reach: short to medium reach fiber links (data center and metro)

How to use

Insert the QSFP28 transceiver into a compatible QSFP28 port on a switch, router or optical line card with the keyed side oriented according to the host port. Use MPO/MTP fiber patch cables terminated and mapped for CWDM4 signals; ensure proper LC/MPO breakout or MTP harness mapping if connecting to duplex interfaces. After insertion, verify link status through the host device management interface and monitor optical diagnostics if available. To remove, power down the specific port if recommended by the host and gently extract the module by the release latch.

Recommendations

Ensure compatibility with the host device and network optics policy before deployment. Use appropriate MPO/MTP cabling with correct polarity and fiber mapping for CWDM4, and maintain clean connector endfaces to prevent signal loss. Observe manufacturer thermal and handling guidelines and operate the module within the specified ambient conditions for reliable 100G performance.
