C-LIGHT 64G SFP56 optical transceivers are designed for high-speed network environments requiring up to 64Gb/s bandwidth in a compact SFP56 form factor. The modules combine high data throughput with low-latency optical connectivity for demanding data communication applications.
The product family provides two distinct optical configurations: an 850nm multimode version for 100m links and a 1310nm single-mode version for 10km transmission. This approach allows the 64G SFP56 platform to address both short-range high-density connections and longer fiber links without using the same optical configuration for every deployment.
Provides up to 64Gb/s optical transmission capacity for bandwidth-intensive networking and high-performance data communication environments.
The compact SFP56 package is designed for high-density network equipment where increased bandwidth must be delivered within a small pluggable footprint.
The CL64GSFP56SR configuration uses 850nm optics and multimode fiber for short-distance links up to 100m.
The CL64GSFP56LR configuration operates at 1310nm and supports transmission up to 10km over single-mode fiber.
Both listed configurations use an LC connector for practical integration with compatible fiber optic network equipment.
The communication protocol complies with the applicable IEEE 802.3/bs/cd specifications for the supported high-speed networking environment.
The interface protocol follows SFF-8472, supporting standardized management and monitoring functions for compatible optical platforms.
The module follows the SFP56 MSA packaging approach for integration into compatible SFP56 host equipment.
The 64Gb/s SFP56 platform provides high-speed optical connectivity for data center switching and server-side network infrastructure.
High-bandwidth optical links can support communication between computing, storage, and networking resources in cloud infrastructure.
The 10km single-mode configuration provides an option for longer optical connections within carrier and telecommunications network environments.
The high data rate is suitable for network architectures handling large volumes of data where optical bandwidth is an important performance factor.
The SFP56 form factor allows network equipment manufacturers and operators to deploy high-speed optical ports without requiring a larger module footprint.
The 100m multimode configuration provides a practical solution for short optical connections between compatible high-speed network devices.
The 10km single-mode version can be used where network equipment needs to be connected across longer fiber paths.
The 64Gb/s optical interface provides a path toward higher-capacity connectivity in network environments moving beyond lower-speed optical platforms.
The product family separates short-range and extended-range requirements into dedicated optical configurations, making module selection more straightforward.
With 64Gb/s throughput in an SFP56 form factor, the module combines high optical capacity with the space efficiency required by dense network equipment.
C-LIGHT positions the 64G SFP56 for environments where bandwidth, latency, and transmission efficiency are important, including data centers, cloud computing, telecom networks, and big data facilities.
C-LIGHT states that the 64G SFP56 is compatible with switches from more than 100 brands, supporting deployment across different network equipment platforms.
C-LIGHT states that every optical module passes initial testing, final testing, and factory inspection as part of its quality-control process.
C-LIGHT provides spot supply, customized services, technical guidance, and after-sales support for different optical networking requirements.
A 64G SFP56 optical transceiver is a high-speed pluggable optical module that supports up to 64Gb/s transmission in the compact SFP56 form factor.
C-LIGHT currently lists a 100m multimode version and a 10km single-mode version for the 64G SFP56 product family.
The 100m CL64GSFP56SR uses 850nm optics with multimode fiber, while the 10km CL64GSFP56LR uses 1310nm optics with single-mode fiber.
The listed 100m and 10km configurations both use an LC optical connector.
The product family supports both multimode fiber for the 100m configuration and single-mode fiber for the 10km configuration.
The product communication protocol complies with IEEE 802.3/bs/cd, the interface protocol complies with SFF-8472, and the packaging follows SFP56 MSA requirements.
C-LIGHT identifies data centers, cloud computing environments, telecom operator networks, and big data processing centers as suitable application environments for the product.
C-LIGHT 64G SFP56 optical transceivers provide a high-bandwidth optical solution for network environments that require up to 64Gb/s connectivity in a compact SFP56 package. With an 850nm MMF configuration for 100m links and a 1310nm SMF configuration for 10km transmission, the product family offers differentiated options for short- and extended-distance deployments across data centers, cloud infrastructure, telecom networks, and high-volume data processing environments.
