Wave2Wave Solution has expanded its EDGE cable fabric family with the addition of QSFP28 copper-based, direct attached cables (DAC). With this addition, the EDGE cable fabric family now supports a broad set of data rates to meet businesses data centre infrastructure needs.

EDGE is a single cable product family to build a network fabric for spine-and-leaf, data centre infrastructure, and server rack-and-stack environments. It simplifies infrastructure design and purchasing as it allows for all needed items to be purchased within a single family enabling businesses to standardize their cable infrastructure and testing across all systems. The QSFP28 DAC offering supports higher data rates – now up to 100Gbp/s – with near-zero wire speed latency and no power consumption, reducing data centre energy use, CAPEX and OPEX. These offerings are ideal for applications including fibre channel over Ethernet; data storage; and data centre, storage area, telecommunications and enterprise networks.

“The newest addition to the EDGE cable fabric family, QSFP28 DAC, cuts down time to deployment in the data centre significantly,” said David Wang, founder and chief executive officer of Wave2Wave. “With these turn-key offerings, operators and integrators can build a spine-and-leaf cluster or a server rack with hundreds of cables within an hour – an undertaking that would typically take days to build otherwise.”

Features of the QSFP28 DAC offering include:

  • Four-channel, full duplex passive copper cable transceiver
  • Up to 25 Gbp/s per channel, maximum aggregate data rate of 100 Gbp/s
  • Conforms to SFF-8665
  • IEEE 802.3bg 100 GEBASE-CR4
  • Copper link length up to 3 meters
  • Power supply of +3.3V
  • Low crosstalk
  • I2C-based two-wire serial interface for EEPROM signature that can be customized
  • Operating temperature of 0-70 degrees Celsius
