1m (3ft) Arista CAB-O-4Q-400G-1M Compatible 400G OSFP IHS/Finned Top to 4 x 100G QSFP56 2 x 50G PAM4 Passive Copper Breakout Cable

The Arista Compatible 400G OSFP to 4x 100G QSFP56 DAC breakout cable assembly is designed to meet the high density requirements of standard and combo connector configurations. OSFP pluggable solutions enable 400G transmission. This hot-swappable transceiver integrates 8 transmit and 8 receive channels. It is fully compliant with SFF-8665, SFF-8436, OSFP MSA, and IEEE802.3cd standards.
OSFP to 4x QSFP56 cable assemblies are high performance, high bandwidth and cost effective interconnect solutions that support 400G standard applications with different data rates. FS currently offers 400G OSFP to 4x 100G QSFP56 DAC in lengths of 0.5, 1, 1.5, 2, 2.5, and 3 metres, ideal for SDN, ML, and Cloud Computing.
Note："Finned-top" transceivers are now called "Integrated Heat Sink" (IHS) as the cooling fins are integrated into the OSFP connector metal top. Commonly used in air-cooled switches. "Flat-top" transceivers are now called "Riding Heat Sink" (RHS) as the cooling fins ride on top of the network card or systems internal cages. This is used for both air-cooled and liquid-cooled applications for DGX, ConnectX-7 and BlueField-3 DPUS.
