Product Overview

The Optical Transceiver Module CC-QKKLL8L-SD is a high-performance 100G QSFP28 ZR4 transceiver designed for long-haul data transmission. It supports 103 Gbps data rates over single-mode fiber (SMF) with a reach of up to 80 km. Compliant with IEEE 802.3ba and QSFP28 MSA standards, this module integrates advanced cooling EML transmitters and SOA+PIN receivers for reliable operation in demanding environments.

Key Features

• Supports 103 Gbps data rate over 80 km on G.652 SMF
• 4x28Gbps LAN-WDM cooling EML transmitter array
• SOA + PIN and TIA receiver array with high sensitivity
• Digital Diagnostic Monitoring via I²C interface
• Low power consumption: < 7.5W with single 3.3V supply
• Operating temperature: -40°C to +85°C

Technology & Standards

This optical module utilizes LAN-WDM technology with four wavelengths centered at 1295.56 nm, 1300.05 nm, 1304.58 nm, and 1309.14 nm. It complies with QSFP28 MSA, IEEE 802.3ba, and meets Class 1 FDA and IEC60825-1 laser safety standards. The module also supports retimed electrical interfaces for signal integrity.

Working Principle

The transceiver converts electrical signals into optical signals using four EML-based transmitters, each operating at a specific wavelength. These signals are multiplexed and transmitted over a single fiber. On the receiver side, a SOA amplifies the incoming optical signal before it is demultiplexed and converted back to electrical signals by a PIN and TIA array.

Applications

Ideal for 100GBASE-ZR4 Ethernet applications, this Optical Transceiver Module is suited for data centers, telecommunications, and enterprise networks requiring high-speed, long-distance connectivity. It is commonly deployed in backbone networks, metro rings, and inter-data center links.
