Nortel deploys optical network expansion for Chunghwa Telecom

15 January 2004 Taipei Taiwan Lightwave -- Nortel Networks has deployed a DWDM optical long haul network expansion for Chunghwa Telecom, connecting four National Center for High Performance Computing (NCHC) backbone nodes located in the major cities of Taipei, Hsinchu, Taichung, and Tainan.

15 January 2004 Taipei Taiwan Lightwave -- Nortel Networks has deployed a DWDM optical long haul network expansion for Chunghwa Telecom, connecting four National Center for High Performance Computing (NCHC) backbone nodes located in the major cities of Taipei, Hsinchu, Taichung, and Tainan.

The network, based on Nortel Networks OPTera Long Haul 1600 Optical Line Systems, positions Chunghwa Telecom to provide multiple managed 10-Gbit/sec wavelength services to NCHC. This allows NCHC to address the expected growth in bandwidth requirements for the Taiwan Advanced Research & Education Network (TWAREN), a national research and information networking project initiated by the National Science Council of Taiwan.

"This Nortel Networks solution will help us enable TWAREN to provide an integrated, ultra high-bandwidth resource to cover grid computing for national research bureaus and the high-tech research laboratories of top-ranking universities," reports Tien-yong Lee, chief engineer, Northern Taiwan Business Group, Chunghwa Telecom.

Nortel Networks' OPTera Long Haul 1600 is a 10-Gbit/sec platform that uses DWDM to split light into as many as 80 channels to maximize capacity on each fiber pair and offers cost-effective scalability to 0.8 Tbits/sec. The long haul system uses Raman amplification to boost the optical signal to achieve greater distances. Providing repeaterless submarine links of up to 350 km, it eliminates the need for costly submerged repeaters, positioning service providers to drive lower capital and operating costs compared to traditional submarine solutions, say company representatives.
