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

The Transceiver CBO QSFP28-100G-CWDM4 BO28L13602D is a 100G CWDM4 fiber optic transceiver in a QSFP28 form factor intended for high‑speed data links. The module implements four CWDM channels to enable 100 Gigabit Ethernet connectivity over duplex single‑mode fiber, offering a compact, hot‑pluggable interface for data center interconnects, switch uplinks and other short‑ to medium‑reach network links. The design supports standard QSFP28 electrical and optical interfaces to simplify integration with compatible switches and routers.

Advantages

This QSFP28 CWDM4 transceiver delivers 100G throughput in a small, hot‑swappable package that reduces space and power per lane compared with multiple lower‑rate modules. CWDM4 wavelength multiplexing allows use of single‑mode fiber with cost‑effective cabling while maintaining lane isolation and consistent performance. The module is suitable for straightforward replacement and upgrades, minimizing downtime during maintenance or capacity expansion.

Suitable for

• 100 Gigabit Ethernet links in data centers
• Switch‑to‑switch uplinks and leaf‑spine interconnects
• Server aggregation and top‑of‑rack connectivity
• Short‑ to medium‑reach single‑mode fiber links using CWDM4

Key specifications

• Form factor: QSFP28
• Data rate: 100 Gbit/s aggregate (4 × 25 Gbit/s lanes)
• Optical standard: CWDM4 wavelength multiplexing
• Fiber type: single‑mode fiber
• Connector interface: duplex LC (or compatible duplex interface for CWDM4)
• Hot‑pluggable electrical interface compatible with QSFP28 ports
• Typical application reach: short to medium distance links (data center interconnects and uplinks)

How to use

Install the transceiver into a compatible QSFP28 port on the switch or router while the host device is powered on, taking care to align and seat the module fully until it clicks into place. Connect duplex single‑mode fiber cables with the appropriate LC connectors, ensuring correct transmit/receive orientation. Verify link status and diagnostics through the host device management interface; monitor optical parameters and link state to confirm proper operation. For removal, unlock the module latch and pull the transceiver straight out to avoid damage to the port or module.

Recommendations

Use clean, certified single‑mode fiber and maintain lint‑free handling of connectors. Observe manufacturer guidance for operating temperature and ESD precautions, and confirm compatibility with the host switch or router firmware before deployment to ensure full interoperability and stable 100G operation.
