Huawei announces 100G Passive Optical Network innovation

Telecom network vendor Huawei on Monday announced its innovation in the 100G – Passive Optical Network (100G-PON) optical access.

The Chinese telecom equipment supplier tested the new 100G-PON over a 20km transmission and ensure that the system is compatible with other PON systems on the ODN. In the future, Huawei said, the 100G-PON system will be able to support 200 Gbit per second per port by supporting more wavelength paths.

Huawei, which competes with ZTE and Alcatel-Lucent in the broadband technology market, said the new 100G-PON technology uses a hybrid time-division and wavelength-division architecture to support a 4 x 25 Gbit/s downstream rate and a 4 x 10 Gbit/s upstream rate, verified by way of the lab prototype and enables 100 Gbit/s access rate per port on existing optical distribution networks (ODNs).

The technology also establishes compatibility between 100G PON and GPON/10GPON/40G TWDM PON, allowing carriers to execute upgrades to access networks, said Huawei in a statement.

Jeff Wang, president, Access Product Line, Huawei, said the 100G-PON technology system will be able to meet the increasing demands of home bandwidth, including cloud services, smart home services and 4K or 8K ultra-high definition videos.

This apart, the 100G-PON system can also support backhaul for Fiber to the Curb / Basement / Office and mobile stations. Huawei said the breakthrough also establishes compatibility between 100G-PON, Gigabit-capable Passive Optical Networks (GPON), 10G-PON and 40G-TWDM PON allowing carriers to execute upgrades to access networks.

Huawei optical access innovation lab considered the three different methods available to improve PON access rates; increasing single wavelength rate, increasing the number of wavelength paths and improving the utilization of the electronic spectrum.

Last week, ZTE, another Chinese telecom network vendor, said it achieved single carrier 400G wavelength-division multiplexing (WDM) signal transmission over 3000km, traversing 10 reconfigurable optical add-drop multiplexers (ROADMs) with an improved frequency spectrum of 4b/s/Hz.

The transmission, carried out using Nyquist filtering technology, fulfills ZTE’s objective for future 400G and optical transmission – single-carrier per channel and single receiver transmission – for which ROADM is a necessary feature.
