Fiber optic 40G transceiver CBO GP-QSFP-40GE-1LR for QSFP+ ports, single-mode long reach

CBO GP-QSFP-40GE-1LR is a 40 Gigabit fiber optic transceiver compatible with QSFP+ ports, engineered for single-mode long-reach connections. The module provides 40G Ethernet transmission over single-mode fiber, enabling high-speed uplinks and aggregation between network core devices and data center switches. Designed for straightforward installation into QSFP+ cages, the transceiver supports standard 40GBase-LR optics for reliable long-distance links.

Advantages

The transceiver delivers a compact QSFP+ form factor that consolidates four 10G lanes into a single 40G interface, reducing port density and simplifying cabling. Built for single-mode long-reach use, it supports extended distances typical for campus backbones and data center interconnects. The module follows standard optical specifications to ensure interoperability with QSFP+ slots and compatible equipment from different vendors.

How to use

Install the transceiver into a QSFP+ cage on a compatible switch or router until it seats securely. Connect single-mode fiber with LC duplex connectors, observing fiber polarity. Verify link status through the host device management interface and confirm 40G link negotiation. For removal, follow equipment procedures to hot-swap or power down per the host device guidance if required.

Recommendations

Handle the transceiver with ESD precautions, keep dust caps on connectors when not in use, and ensure fiber connectors are clean before mating. Use certified single-mode fiber cabling and maintain proper bend radius to preserve signal integrity for long-reach 40G links.
