C-LIGHT 40G AOC active optical cables are designed for short-distance 40Gbps optical connections between switches, servers, and high-performance computing equipment. The integrated active optical construction combines the optical interfaces and multimode fiber into a single cable assembly, simplifying high-speed network installation.
The 40G AOC family includes direct 40G QSFP+ to QSFP+ configurations as well as 40G/10G multi-rate options. This allows the product to address both native 40G connections and network architectures where a higher-speed QSFP+ port needs to interface with multiple 10G links.
Based on 850nm multimode optical transmission and OM3 fiber, the current C-LIGHT configurations support cable lengths from 0.5m to 30m and are intended for data center, high-performance computing, and other short-reach networking applications.
The AOC provides 40Gbps high-speed connectivity for compatible Ethernet and high-performance networking equipment.
The QSFP+ interface provides a compact four-channel platform for 40G network equipment and high-density switch connections.
C-LIGHT provides a 40G/10G configuration for network architectures that combine 40G uplinks with lower-speed 10G connections.
The multi-rate configuration can be used for 40G-to-4x10G network architectures, providing a practical way to connect different generations of Ethernet equipment.
The product uses 850nm optical transmission for short-distance multimode fiber connections.
OM3 fiber is specified for the current 40G AOC configurations and is suited to short-reach data center cabling.
The available cable range covers short connections between equipment located in the same rack or nearby rack positions.
C-LIGHT specifies InfiniBand NDR support for the 40G AOC product family, extending its use to high-performance computing environments.
40G AOCs can connect compatible switches and network devices where high bandwidth is required over short optical distances.
The 40G AOC platform provides short-reach optical connectivity for HPC systems and computing clusters requiring high-throughput network links.
Compatible server and network interfaces can be connected using QSFP+ active optical cables for high-speed data exchange.
40G AOC configurations supporting InfiniBand can be used in specialized high-performance computing and cluster networking environments.
Multi-rate configurations provide a practical connection method when a 40G network interface needs to communicate with multiple 10G ports.
The 0.5m to 30m cable range is appropriate for equipment connections within a rack and between adjacent racks.
40G AOC solutions can support high-bandwidth connections in enterprise data centers that continue to operate 40G network infrastructure.
The availability of both native 40G and 40G/10G configurations provides flexibility when upgrading network equipment at different speeds.
The product family covers direct 40G connections as well as 40G/10G configurations, giving network operators more choices during equipment deployment and migration.
The QSFP+ form factor supports high-speed connectivity while keeping the physical interface compact for dense network equipment.
The multi-rate version can support 40G-to-4x10G connectivity, making it useful when integrating different Ethernet port generations.
The 0.5m to 30m range targets the short optical connections commonly used inside data centers and computing facilities.
Support for Ethernet and InfiniBand environments makes the 40G AOC suitable for both general networking and specialized computing infrastructures.
The product page specifies IEEE 802.3ba, SFF-8436/8431, and QSFP+ MSA specifications for communication, interface, and packaging requirements.
C-LIGHT states that the 40G AOC is compatible with network switches from more than 100 brands.
C-LIGHT provides product testing, technical guidance, customization, long-term maintenance, and compatibility support for network deployments.
A 40G AOC is an active optical cable designed to provide 40Gbps short-distance connectivity with optical components integrated into the cable assembly.
The C-LIGHT 40G AOC uses the QSFP+ form factor for compatible 40G network equipment.
Yes. The product specifications include a 40G/10G QSFP+ to QSFP+ configuration in addition to the native 40G version.
Yes. The 40G/10G configuration can be deployed in network architectures where a 40G connection is distributed to four 10G links.
The current product specifications use 850nm optical transmission over OM3 multimode fiber.
C-LIGHT specifies 0.5m to 30m transmission distances for the 40G AOC configurations.
Yes. C-LIGHT specifies InfiniBand NDR support for the 40G AOC product family.
The product page specifies IEEE 802.3ba for the communication protocol, SFF-8436/8431 for the interface protocol, and QSFP+ MSA for the packaging protocol.
C-LIGHT 40G QSFP+ AOC active optical cables provide a flexible short-reach interconnect solution for data centers, high-performance computing systems, and high-speed network infrastructure. The product family combines native 40G QSFP+ connectivity with a 40G/10G multi-rate option, while 850nm optical transmission, OM3 multimode fiber, and 0.5m to 30m cable lengths address common short-distance deployment requirements. With support for InfiniBand environments and 40G-to-10G network architectures, the 40G AOC series can serve both established 40G infrastructure and mixed-speed network environments.
