Exar Optimizes 2xGbE Transport

Exar Corporation has introduced an optimized Gigabit Ethernet (GbE) Mapper for access and transport applications.
According to the company in this PR Newswire release, the GEM250 SoC and included DeviceManager software enable rapid development and deployment of dual GbE transport solutions for Coarse/Dense Wavelength Division Multiplexing (C/DWDM) networks.


“Demand for broadband connectivity over wired and wireless networks for consumer and business applications has driven increasing penetration of GbE as a backhaul interface of choice on platforms such as cable modem head ends, DSLAMS and 3G/4G Base Stations. Dedication of individual
fibers or even wavelengths for GbE transport is placing considerable stress on the existing optical infrastructure.

“With direct connection to GbE PHYs on the client side and SDH/SONET SerDes on the line side, GEM250 combines all the functions necessary to multiplex 2 Gigabit Ethernet streams into a single 2.5Gb/s signal. Integrated GbE MACs provide Ethernet statistics while Ethernet frames can be encapsulated with HDLC or GFP. All SDH/SONET Regenerator/Multiplex Section and Trail/Path monitoring functions are also implemented in hardware.”
