Optical Transceiver CBO QSFP+KT-LR compatible QSFP module for long‑reach fiber — CBO QSFP+KT-LR-BO

The BlueOptics Optical Transceiver CBO QSFP+KT-LR-BO is a QSFP-compatible module engineered for long-reach single‑mode fiber links. Designed to fit QSFP form-factor ports, this transceiver enables high-density network devices to establish optical connections across extended distances. It is suitable for use in data center uplinks, campus backbones and core network segments that require interoperable, rack‑mountable optical interfaces.

Advantages

The module combines QSFP form-factor interoperability with long‑reach optical performance to support consolidated, space-efficient deployments. It offers reliable fiber connectivity suitable for high-bandwidth aggregation and uplink ports while maintaining compatibility with standard QSFP sockets. The transceiver is intended for straightforward integration into networking switches and routers where predictable optical link behavior and physical compactness are important.

Suitable for

• Data center uplinks and spine connections
• Campus network backbones and building-to-building links
• Core network aggregation and metro links requiring long‑reach single‑mode fiber
• High-density switching environments with QSFP ports

Key specifications

• Form factor: QSFP-compatible module for 4-lane optical interfaces
• Fiber type: single‑mode fiber (long‑reach)
• Application: long-distance optical links for uplinks and aggregation
• Compatibility: interoperable with standard QSFP ports and QSFP+ host devices
• Physical: hot-pluggable small form-factor transceiver

How to use

Install the transceiver into an available QSFP port on compatible network equipment while the device is powered down or following the vendor's hot-swap guidance. Connect appropriate single‑mode fiber cabling using matched connectors and ensure correct end-to-end fiber polarity. After physical installation, verify link status and configure host interfaces as required by the switch or router operating system. Monitor optical parameters and link diagnostics through the host device management tools to confirm stable operation.

Usage recommendations

Use clean, certified single‑mode fiber cables and follow connector cleaning procedures to maintain signal quality. Match transceiver optical specifications with the fiber route and verify distance and loss budgets before deployment. When integrating into multi-vendor environments, test interoperability and link stability under expected traffic loads to ensure consistent performance.
