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

The Transceiver CBO QSFP28-100G-CWDM4 BO28L13602D 100G CWDM4 QSFP28 fiber optic module is a compact, hot-pluggable 100 Gigabit Ethernet optical transceiver designed for short- to medium-reach CWDM4 links. Built in a QSFP28 form factor, this BlueOptics module enables high-density deployment in data centers and network aggregation points, supporting standardized four-wavelength coarse wavelength division multiplexing to carry 100 Gbps over single-mode fiber. The module is intended for use with compatible 100G ports and provides a space-efficient option for switch-to-switch connections, top-of-rack uplinks, and inter-rack links where CWDM4 signaling and optical reach are required.

Advantages

This QSFP28 CWDM4 transceiver offers high port density and hot-pluggable convenience, allowing fast field replacement without powering down equipment. It supports 100 Gigabit Ethernet over single-mode fiber using CWDM4 wavelengths, which reduces the number of fibers needed compared with parallel solutions. The QSFP28 form factor is compatible with a wide range of modern 100G switches and routers, enabling straightforward integration into existing network infrastructure while preserving rack space.

Suitable for

• Data center interconnects and spine-leaf architectures
• Switch-to-switch and switch-to-router 100G uplinks
• Top-of-rack and aggregation links requiring single-mode CWDM4 optics
• High-bandwidth server uplinks and storage networking

Key specifications

• Data rate: 100 Gbps (QSFP28)
• Optical technology: CWDM4 (four coarse wavelength channels)
• Fiber type: single-mode fiber (SMF)
• Form factor: QSFP28, hot-pluggable
• Interface: duplex LC or MPO depending on implementation (verify connector type before installation)
• Typical reach: designed for short- to medium-range CWDM4 links (refer to vendor reach specifications for exact distances)

How to use

Install the QSFP28 transceiver into a compatible 100G QSFP28 port by aligning the module with the port and pressing it into place until it latches. Connect single-mode optical fiber with the appropriate CWDM4-compliant connector type, ensuring clean connectors and correct polarity. Confirm that the host device recognizes the module and that the port is configured for 100 Gigabit operation. Monitor link status and optical parameters via the host system management interface to verify proper operation.

Recommendations

Before installation, check compatibility with your switch or router vendor and verify connector type and required optical reach. Use fiber-cleaning tools to remove dust from connector endfaces, and avoid bending the fiber beyond its minimum bend radius. Replace the module with a compatible QSFP28 CWDM4 unit when optical performance degrades or when migrating to a different optical standard.
