CBO transceiver QSFP-40G-LR 40GBASE-LR QSFP+ 1310nm single-mode fiber

The CBO transceiver QSFP-40G-LR is a 40GBASE-LR QSFP+ fiber optic module that operates at 1310 nm for single-mode fiber connections. Designed for high-speed uplinks and long-reach links, this QSFP+ transceiver provides 40 Gbps transport between switches, routers and aggregation equipment in data centers and enterprise networks. The module fits QSFP+ ports and is intended for single-mode fiber infrastructure where reliable long-distance transmission is required.

Advantages

This QSFP+ transceiver supports 40 Gbps line rate with a 1310 nm wavelength optimized for single-mode fiber, enabling extended reach between network devices. The compact QSFP+ form factor allows for high-density port deployment in rack-mounted switches and aggregation equipment. Compatibility with standard QSFP+ interfaces simplifies replacements and upgrades without major changes to existing hardware. The module is engineered for stable optical performance and predictable latency suitable for core and distribution layers.

How to use

Insert the QSFP-40G-LR module into a compatible QSFP+ port on your switch or router following the equipment manufacturer's hot-plug procedure. Connect appropriate single-mode fiber patch cords to the transceiver's LC duplex interface, observing correct polarity. Verify link status and speed in the host device management interface; the device should negotiate 40 Gbps operation. For safe handling, avoid touching the optical interfaces and use dust caps when the module is not connected.

Recommendations

Use high-quality single-mode fiber and LC duplex connectors to achieve specified reach and signal integrity. Confirm compatibility with your network equipment firmware and QSFP+ port specifications before deployment. Maintain clean optical endfaces and follow standard fiber handling procedures to prevent signal loss.
