Description：

40G QSFP to 4xSFP+ active optical cable is a high-performance, low-power, long-distance interconnection solution that supports 40G.

40G QSFP to 4xSFP+ is a combination of 4 full-duplex channels, each of which can transmit data at a rate of up to 10GB/s, providing an aggregation rate of 40GB/s.

40G QSFP to 4xSFP+ active optical cable (AOC) can be used as an alternative to QSFP passive and active copper cables.

Features ：

Electrical interface compliant to QSFP+ connector

(SFF-8436) and SFP+ connectors (SFF-8431)

Hot Pluggable
850nm VCSEL transmitter, PIN photo-detector receiver
Operating case temperature: 0 to 70℃
3V power supply voltage
All-metal housing for superior EMI performance

Application：

40 Gigabit Ethernet
Fibre Channel Applications
InfiniBand QDR, SDR, DDR
Servers, switches, storage and host card adapters
