100G QSFP28 LR4 Optical Transceiver — CC-QKKLL1L-SD

Deliver high-performance 100G connectivity with our optical transceiver module, designed for long-reach data center applications. This optical module supports up to 10km on single-mode fiber using four independent LAN-WDM channels, featuring low power consumption and comprehensive digital diagnostics. Ideal for 100G Ethernet and high-performance computing environments.

Key Features

• Hot-pluggable QSFP28 form factor
• 4 independent LAN-WDM channels (1294-1310nm)
• Reach up to 10km on single-mode fiber
• Low power consumption < 4.5W
• Wide operating temperature range: 0°C to 70°C
• Digital diagnostic monitoring via I2C interface
• Compliant with 100GBASE-LR4 standards

Technology and Standards

This optical transceiver module utilizes WDM (Wavelength Division Multiplexing) technology with four distinct wavelengths to achieve 100G throughput. It complies with IEEE 802.3ba standards for 100GBASE-LR4 applications and features advanced diagnostics for real-time performance monitoring.

Working Principle

The optical module employs four distributed feedback (DFB) lasers operating at different wavelengths to transmit data over single-mode fiber. The receiver section uses four PIN photodiodes to detect and convert the optical signals back to electrical format. Internal CDR circuits ensure signal integrity across the 10km distance.

Applications

• Data center interconnects and backbone networks
• 100G Ethernet switches and routers
• High-performance computing clusters
• Telecom and service provider networks
• Enterprise core network infrastructure
