Product Overview
The Optical Transceiver Module model CC-QKKLL4L-SD is a high-performance QSFP28 form factor transceiver designed for 100G Ethernet applications. It supports data transmission over single-mode fiber up to 40 km without FEC, making it ideal for long-haul data center interconnects and telecom backbones. This optical module integrates four 25G LAN-WDM lanes with EML lasers and APD detectors, ensuring low power consumption and high reliability.
Key Features
- Hot-pluggable QSFP28 form factor
- 4×25.78125 Gb/s LAN-WDM lanes
- Up to 40 km transmission over SMF
- Low power consumption < 4.5 W
- Operating temperature: 0°C to 70°C
- I²C management interface
- RoHS compliant and lead-free
Technology & Standards
This Optical Transceiver Module complies with IEEE 802.3ba, SFF-8436, SFF-8636, and QSFP28 MSA standards. It uses EML laser technology and APD array receivers for high sensitivity and superior performance in demanding environments.
Working Principle
The module converts electrical signals into optical signals using four EML lasers, each operating at a specific LAN-WDM wavelength. The signals are multiplexed into a single fiber for transmission. On the receive side, an APD array detects the optical signals, demultiplexes them, and converts them back to electrical outputs.
Applications
- 100G Ethernet data centers
- Telecommunication networks
- Cloud infrastructure interconnects
- Enterprise network backbones
