Description
The 40G QSFP+ to 4× Duplex LC Active Optical Cable (AOC) is a parallel optical interconnect designed for 40G Ethernet SR applications, providing direct connectivity between one QSFP+ port and four duplex LC interfaces. The QSFP+ end integrates four 850nm VCSEL transmitters and four PIN photodetectors, with each optical lane supporting up to 10.3125Gbps for 40Gbps-class aggregate transmission over multimode fiber. By integrating the optical components into the QSFP+ connector, the cable eliminates the need for a separate transceiver at the QSFP+ end and simplifies deployment to existing LC-based fiber infrastructure. Its armored construction, LSZH jacket, low power consumption, and I2C-based DDM support make it suitable for data centers, server networks, storage systems, and other high-density short-range 40G applications.

Q&A
What is the purpose of the 4× duplex LC configuration?
The cable converts one compatible 40G QSFP+ interface into four independent duplex LC optical connections, providing four transmit and four receive optical paths for connection to LC-based fiber infrastructure.
Does the cable require a separate transceiver at the QSFP+ end?
No. The QSFP+ assembly integrates four 850nm VCSEL transmitters and four PIN photodetectors, eliminating the need for a separate optical transceiver at that end.
What data rate does each optical lane support?
Each of the four optical lanes supports data rates of up to 10.3125Gbps, providing 40Gbps-class aggregate connectivity.
Can DDM information be monitored?
Yes. The QSFP+ assembly supports Digital Diagnostic Monitoring (DDM) through the I2C interface, allowing compatible host equipment to access available monitoring information.
What type of fiber infrastructure is it designed to connect to?
The cable is designed for compatible multimode optical infrastructure using duplex LC interfaces, making it useful for integrating 40G QSFP+ equipment with existing LC-based fiber connections.
