New 50G transceiver product household

As community operators look to improve their medium-speed Ethernet hyperlinks, they will reap the benefits of a Cisco’s new optical transceiver product household “SFP-50G”. These modules are 50G transceivers in a kind issue referred to as SFP56 (see Determine 1). They ship double the information charge of SFP-25G (SFP28 kind issue) and in the identical primary SFP kind issue.

In contrast to QSFP-40G and QSFP-100G transceivers, which each use 4 electrical lanes at decrease speeds (4 x 10G and 4 x 25G, respectively), SFP-50G encompasses a single electrical lane. Because of this, it may possibly interface instantly with the most recent era swap ASICs that incorporate 50G serializers/deserializers (SerDes), eliminating the necessity for added gearboxes with PAM4 encoders/decoders. Thus, SFP-50G offers a lift in efficiency of 50G with a design that minimizes price, house and energy consumption.

Determine 1: SFP-50G Transceiver

From a historic perspective, let’s have a look at the evolution of the QSFP-100G and SFP-25G markets, each based mostly upon the 25G SerDes. The primary gadgets to succeed in the market have been the QSFP-100G optical modules, based mostly on 4 electrical lanes of 25G SerDes within the QSFP28 kind issue. This allowed transceiver module suppliers to supply 100G functionality. SFP-25G modules weren’t broadly accessible till years later. An identical dynamic is in play now for SFP-50G. Due to the broad give attention to QSFP56-DD 400G modules, the marketplace for 50G SerDes and ASICs is now mature, leading to excessive reliability and low price. This case permits the event and business progress of SFP-50G modules.

The SFP56 worth proposition

In comparison with the workhorse SFP-25G, the SFP-50G delivers double the information charge in the identical kind issue. Traditionally, that development has led to dramatic decreases in price per bit. Change distributors are already creating switches with SFP ports that may assist 1G, 10G, 25G, and 50G charges. These merchandise give community operators the liberty to function every hyperlink on the information charge that most closely fits demand at any given time simply by deciding on the suitable transceiver sort: copper, SMF or MMF and the specified velocity in SFP, SFP-10G, SFP-25G and now SFP-50G.

To assist this development, Cisco’s SFP-50G product household accommodates a complete portfolio of transceivers starting from copper-based options of some meters to optical modules with reaches of as much as 15 km and even higher sooner or later. These transceivers assist 50G and 25G twin charge, which permits them to attach on the new the 50G charge whereas additionally connecting with 25G transceivers.  This provides community operators a cheap migration path from 25G to 50G by enabling partial community upgrades.

Community operators want versatile, dependable improve paths to serve a wide range of shopper wants. SFP-50G provides them the choice of a big capability improve in a well-recognized kind issue that helps scale back price per bit. Cisco’s SFP-50G transceiver product line, a broad 50G portfolio, lets community operators select the optimum answer for a wide range of community segments.
