The Things You Need to Know about 100GBASE-CR4 Ethernet Standards
2016-12-06
Introduction:
In this article we will discuss about the 100GBASE-CR4 Ethernet standard and what are the difference between 100GBASE-CR4 and 100GBASE-KP4, So you can have a basic understanding for 100GBASE-CR4 technology to understand the basic solutions to 100GBASE-CR4. Also, you can check the compatible Cozlink transceivers to get compatible and cost-effective products.
What is the 100GBASE-CR4 technology?
100GBASE-CR4 cables are suitable for very short links and offer a cost-effective way to establish a 100-Gigabit link between QSFP-100G ports of Cisco switches within racks and across adjacent racks. Cisco currently offers passive copper cables in lengths of x=1, 2, 3, and 5 meters.
What IS the Difference Between 100GBASE-CR4 and 100GBASE-KP4?
100GBASE-CR4: 100 Gb/s transmission using 100GBASE-R encoding and Clause 91 RS‑FEC over four lanes of shielded twinaxial copper cabling, with reach up to at least 5 m
100GBASE-KP4: 100 Gb/s transmission using 100GBASE-R encoding, Clause 91 RS‑FEC, and 4-level pulse amplitude modulation over four lanes of an electrical backplane, with a total insertion loss of less than 33 dB at 7 GHz
