ZTE on Tuesday claimed to have unveiled the industry's first TWDM-PON prototype, a next-generation fibre access technology that will meet the capacity needs of service providers and enterprises in five years time.
Essentially TWDM-PON, or to give its full title, time and wavelength division multiplexing passive optical network, combines the throughput of up to four 10G-PON (also known as XG-PON) units onto a single fibre, quadrupling the bandwidth. It has emerged as standards body FSAN (Full Service Access Network)'s preferred technology for its NG-PON2 (next-generation passive optical network) standard. One of the main reasons why it has become popular is because it doesn't require operators to completely overhaul their networks in order to deploy it.
"It means more bandwidth which means more revenue for operators because it allows them to deliver more services," said Christophe de Saint-Martin, European marketing director at ZTE's solution operator department.
He listed a number of possible applications for ZTE's TWDM-PON solution, including high-bandwidth residential broadband services, mobile backhaul, and high capacity point-to-point fibre connections for enterprises.
"It's unified and future-proof," declared Saint-Martin.
However, despite his proclamations, TWDM-PON has yet to receive the official nod from FSAN or the ITU.
"It is expected to be standardised in 2013," he said.
