C-LIGHT 128G QSFP+ optical transceivers are high-speed parallel optical modules designed to provide an aggregate 128Gbps data rate through four independent 32Gbps channels. The QSFP+ form factor combines high bandwidth with a compact footprint, making the modules suitable for high-density optical networking environments.
The product family includes both multimode and single-mode configurations. The 850nm multimode version supports up to 100m using an MPO connector, while the 1310nm single-mode version supports 2km to 10km transmission through an LC interface. These configurations allow the 128G QSFP+ platform to address different optical link requirements in data center and high-performance computing environments.
The module combines four 32Gbps optical channels to provide a total data rate of 128Gbps for high-bandwidth network connections.
Four parallel optical lanes distribute the overall bandwidth across multiple channels, forming the core architecture of the 128G QSFP+ design.
The compact QSFP+ package supports high-density installation in compatible networking equipment while maintaining a high aggregate optical capacity.
The 850nm multimode version is designed for transmission up to 100m and uses an MPO optical connector for parallel fiber connectivity.
The 1310nm single-mode version supports transmission from 2km to 10km and uses an LC connector for extended optical links.
The product is specified for high-speed networking environments involving 100G Ethernet and InfiniBand applications.
The parallel optical architecture is suited to applications where high bandwidth, low latency, and efficient optical interconnection are important.
The listed configurations are available with commercial and industrial case-temperature options for different deployment environments.
The high aggregate bandwidth and parallel optical architecture make the module suitable for HPC systems requiring fast interconnection between computing resources.
The compact QSFP+ package provides high-density optical connectivity for compatible data center switching and interconnection equipment.
The 128G optical platform can be deployed in compatible InfiniBand environments where high-throughput, low-latency connectivity is required.
The module supports optical connectivity for compatible 100G Ethernet environments and high-speed network architectures.
High-bandwidth optical interconnects can support communication between servers, switches, and computing resources in cloud data center environments.
The 100m multimode configuration is suitable for short optical connections within data center and computing environments.
The 2km to 10km single-mode configuration provides an option for longer connections between network locations and facilities.
The QSFP+ form factor allows network operators to increase aggregate optical bandwidth without requiring a large physical footprint.
The 128G implementation is built around four 32Gbps channels, providing a clear parallel architecture for achieving the aggregate bandwidth.
C-LIGHT provides both 850nm MMF and 1310nm SMF versions, allowing the module to be selected according to link distance and installed fiber infrastructure.
The short-reach multimode configuration uses MPO, while the single-mode extended-reach configuration uses LC, matching the requirements of their respective optical architectures.
The compact form factor makes it possible to deploy high aggregate optical capacity in equipment where front-panel space and port density are important considerations.
C-LIGHT states that 100% of products pass initial testing, final testing, and factory inspection as part of its quality-control process.
C-LIGHT provides technical support, compatibility testing, and customized optical solutions for different network deployment requirements.
