Transceiver CBO QSFP28-100G-LR4 BO28L13610D 100G LR4 optische module

The Transceiver CBO QSFP28-100G-LR4 BO28L13610D 100G LR4 optical module is a QSFP28 form-factor 100 Gigabit Ethernet transceiver designed for long-reach single-mode fiber connections. It implements LR4 wavelength-division multiplexing to carry four 25 Gbps lanes over single-mode fiber, providing a high-capacity optical link for uplinks, core switch interconnects and carrier-grade transport. The module is suitable for deployments that require reliable 100G links across extended distances typical of long-reach single-mode environments.

Advantages

The module supports standardized QSFP28 interfaces and LR4 optics, enabling interoperability with compatible 100G ports and reducing upgrade complexity. Its LR4 wavelength-division multiplexing design allows efficient use of a single fiber pair for high-bandwidth transmission and helps minimize fiber infrastructure changes. The compact QSFP28 form factor provides high port density in switches and line cards while maintaining low power consumption relative to older 100G solutions.

Suitable for

• Data center uplinks between aggregation and core switches
• Core network links in enterprise or service provider environments
• Metro and long-haul single-mode fiber connections requiring 100G capacity
• High-density switch or router line cards with QSFP28 ports

How to use

Install the QSFP28 transceiver into a compatible QSFP28 port on a switch, router or network appliance following the host device manufacturer's module installation guidelines. Ensure both ends of the link use matching LR4-compatible 100G optical modules and that the fiber pair is single-mode and correctly terminated. After insertion, verify link status, lane alignment and port configuration through the host device management interface, and configure required network settings such as speed, FEC and VLANs as needed.

Recommendations

Use clean, properly rated single-mode fiber and comply with connector cleaning procedures to avoid signal degradation. Confirm compatibility with the network equipment vendor's transceiver support list when interoperability requirements are strict. Monitor optical power and port temperature during initial deployment to ensure reliable operation within expected parameters.
