Originally known as IEEE 802.3bs, 400G was officially approved in December of 2017 and is part of a broader family of related technologies including 200G, next generation 100G, and 50G Ethernet. 400G has driven the rapid development and adoption of new pluggable optical mod. The term “exponential improvement” is a bit over used, but in the case of 400G, it is entirely applicable. 1. Gigabit Ethernet, meaning an Ethernet connection that can transmit traffic at a rate of 1 gigabit per second (Gbps), was introduced in 1999. 2. Terabit Ethernetis used to describe a switch fabric capable of handling numerous ports at speeds. Before 100G Ethernet, testing client optics was a much simpler task. Bit error rate (BER) could be quantified for each channel, with “zero” errors over a pre-defined time period often used as the pass/fail criteria. With non-return to zero(NRZ) giving way to PAM-4 modulation and FEC, 400G testing and validation have become much more complex. The sh. Dense Wavelength Division Multiplexing (DWDM) has significantly increased fiber optic bandwidth. Using this method, a single fiber channel can transmit data at speeds of 400 Gb/sec. or more. With the network only as strong (or as fast) as its weakest link, 400G Ethernet bridges the bandwidth gap between the core routers and the DWDM equipment. A 40. The efficiencies gained through 400G implementation ripple throughout the high-speed networking ecosystem. This includes chip and module manufacturers, test equipment and service companies, internet mega-corporations, and telecom providers who rely upon these improvements to keep pace with the insatiable demand. 1.
