ZXWM M900

Features

• Super-large-capacity transmission and modular upgrade

When configured as 10G system, 96/192-wavelength system framework is recommended. The subsystem can perform modular capacity expansion, with transmission capacities of 400Gbit/s, 480Gbit/s, 800Gbit/s, 960Gbit/s and even to 1920Gbit/s available;

When configured as 40G system, C band 96-wavelength system framework is recommended. The subsystem can perform modular capacity expansion, with transmission capacities of 1.6T、1.92T, 3.2T, and 3.84T available, addressing tomorrow’s escalating bandwidth requirements.

• Single-wavelength 40Gbit/s technology

The 40Gbit/s system utilizes ODB, DPSK and RZ-DPQSK modulation formats, which provide better signal-to-noise ratio and enhanced non-linearity. With automatic dispersion compensation (TDC), it is applicable to ultra-long-haul transmission. Furthermore, 40Gbit/s service board employing ODB, DPSK technologies has high slot utilization and lower power consumption.

• Ultra-long-haul transmission capability

10G system configuration supports repeaterless transmission over 5000km; 40G system configuration supports repeaterless transmission over 2000km.

• Full support of OTN functionality

All line interfaces of ZXWM M900 equipment support OTN standard, OTN overhead detection and utilization, and cross-connect scheduling of ODUk granule, in full compliance with G.709 and G.798 Recommendations; ZXWM M900 supports TCM domain management overhead, enables multi-vendor and multi-domain precise fault localization and message transfer, thus implementing interworking of multi-domain and multi-vendor equipments.

• IWF (integrated wavelength feedback) patented technique

Combination of self-patented wavelength centralized monitoring technique and precise temperature control further guarantees the wavelength stability of 50/25GHz wavelength spacing system.

• Highly integrated MUX/DMUX with low power consumption

The unique 80-λ MUX/DEMUX architecture allows for multiplexing/demultiplexing of 80 wavelengths without use of OCI, causing slot occupation and power consumption to decrease by 20% and 50% respectively.

• Wavelength add/drop function

Designed with flexible MUX/DMUX architecture, ZXWM M900 enables agile add/drop of 1-96/192 wavelengths. It supports fixed optical add/drop multiplexing (FOADM) and reconfigurable optical add/drop multiplexing (ROADM) functions.

• Flexible and mature protection schemes

Multiple protection modes are available: 1+1 path protection, 2-fiber bidirectional path shared protection, 2-fber bidirectional multiplex section shared protection, subnet connection protection, 1+1 multiplex section protection and equipment-side 1:N OTU protection. ZTE’s innovative path shared protection technique vastly decreases protection wavelengths used, saving network construction cost.

• Strong service access and aggregation capability

Aggregate STM-1(OC3), STM-4(OC12), STM-16(OC48), STM-64(OC192), STM-256, FE, GE/10GE, FICON, ESCON, FC, ATM, PDH services into 2/8×GE, 4×155M, 4×622M, 4×2.5G, 4×10G, 8×Any, 2/4/8×FC, etc.
