40G QSFP+ to QSFP+ DAC Series

Description

● 40G QSFP+ to QSFP+ DAC:

DAC Direct Attach Copper Cables are further divided into passive copper cable and active copper cable. In most data center, most server to server connections require 2-5 meters, while rack to rack connections are required to be connected by 8-12 meters cables. Passive copper cable are widely chosen by data centers for connecting servers to servers or servers to the Top Of the Rack (TOR) switch as they are passive, consume zero power, have the lowest latency and cost-effective. Active copper cable is less expensive and can support transmission up to 15 meters with low power consumption, which can satisfies the regular interconnection requirement for distance and cooling in most data center. PancomLink offers a wide range of products for 0.5m to 15m lengths and in QSFP+, SFP+ form factors. The unique EEPROM technique has been used to ensure DACs compatible with different brands on the original switches and routers.

QSFP+ DAC based on IEEE 802.3ba and compliant MSA SFF-8436, application in 40G Ethernet, infiniband QDR and Omni-path, suitable for very short distances transmission and offer a highly cost-effective solution to establish a 40-Gigabit link between QSFP+ ports and QSFP+ switches within racks and across adjacent racks. Active DAC design has a signal amplification and a class 4x10G Clock and Data Recovery(CDR) or Equalizer technology to support longer distances than passive DAC cable.
For I2C, there are 2 designs with MCU or with EEPROM, MCU design is for "HPE (H3C)" and some model of "Cisco Switch", the EEprom design is for many brands device.
