## Long description

The Transceiver CBO QSFP-40G-LR4 40GBASE-LR4 1310nm single-mode is an optical module designed for 40 Gbps links over single-mode fiber. It uses the QSFP form factor to provide four-channel 10 G lanes combined for 40GBASE-LR4 operation at 1310 nm, enabling long-reach connections between switches, routers and aggregation equipment. The module is intended for upgrading or replacing optics in compatible 40G ports to support reliable high-speed data transmission in data centers and carrier networks.
Advantages
This QSFP transceiver offers a compact QSFP footprint for high port density and low rack space usage while delivering 40 Gbps aggregated throughput. Designed for single-mode fiber, it supports long-reach links and stable performance over extended distances. The standardized form factor and electrical interface ensure compatibility with equipment that accepts QSFP 40G modules, simplifying upgrades and maintenance.
Suitable for
Long-reach 40G connections between core and aggregation switches
Interconnects linking routers and carrier equipment in metropolitan or campus networks
Upgrading or replacing optics in QSFP-compatible 40G ports
Key specifications
Data rate: 40 Gbps aggregated (four 10 G lanes)
Wavelength: 1310 nm
Fiber type: Single-mode fiber (SMF)
Form factor: QSFP
Transmission type: 40GBASE-LR4 long-reach
Typical application: Long-distance single-mode interconnects
How to use
Install the QSFP module into a compatible 40G QSFP port on the switch or router until it seats securely. Connect single-mode fiber using the appropriate LC breakout or MPO to LC cabling as required by the host equipment and link design. Verify link status on the host device and confirm the port recognizes the 40GBASE-LR4 module. Follow the equipment vendor’s guidelines for hot-swap procedures and handling to avoid electrostatic discharge and contamination of fiber connectors.
Usage recommendations
For reliable performance, use quality single-mode fiber and clean connectors before mating. Ensure the cable plant supports LR4 reach and dispersion characteristics at 1310 nm and follow the host vendor’s compatibility list when selecting replacement optics.
