ZTE Corporation

Strength of ZTE DWDM product: Have constructed two biggest LH DWDM networks

(West Ring of China Mobile in 2002, Indian BSNL national backbone in 2003)

Leader in the field of ULH：in ITU-T SG15 in Oct 2003, ZTE achieved the title of drafter

of ITU-T G.raman. Raman amplifier is the core technology in ULH system.

Leader in the field of optical protection: the only one to provide 4 kinds of optical

protection and hold 90% market share of optical protection in 2003.

Backbone DWDM system: widely used in national and provincial backbone. Large

capacity, mature technology, excellent upgrade ability and outstanding maintenance ability.

Metro DWDM system: mainly used in metropolitan or local network. Large capacity,

advance technology and comprehensive optical protection.
