Description

The QSFP+ active optic cables are a high performance, low power consumption, long reach interconnect solution supporting InfiniBand QDR/DDR/SDR,12.5G/10G/8G/4G/2G fiber

channel ,PCIe and SAS. It is compliant with the QSFP MSA and IEEE P802.3ba. QSFP AOC is an assembly of 4 full-duplex lanes, where each lane is capable of transmitting data at rates up to 11.3Gb/s, providing an aggregated rate of 45.2Gb/s. QSFP+AOC is one kind of parallel transceiver which provides increased port density and total system cost savings.

Absolute Maximum Ratings

The operation in excess of any absolute maximum ratings might cause permanent damage to this module.

Notes:

1. Module circuit ground is isolated from module chassis ground within the module. GND is the symbol for signal and supply (power) common for QSFP modules.

2. The connector pins are each rated for a maximum current of 500mA.

Power Supply Filtering

The host board should use the power supply filtering shown in Figure1.

ESD

This transceiver is specified as ESD threshold 1KV for high speed data pins and 2KV for all others electrical input pins, tested per MIL-STD-883, Method 3015.4 /JESD22-A114-A (HBM). However, normal ESD precautions are still required during the handling of this module. This transceiver is shipped in ESD protective packaging. It should be removed from the packaging and handled only in an ESD protected environment.
