Copenhagen, Denmark — Mintera Corporation, the Lowell, Mass.- based start up developing 40G transport systems for metro-core, regional, long haul and ultra long haul networks, today announced that it has demonstrated error-free transmission of 40 channels at 40 Gbit/s over a record distance of 5,200 km of UltraWave fiber without electrical regeneration.
Details of what it claims to be a world record were presented as a late paper during today's session at the European Conference on Optical Communications (ECOC) here.
The 'breakthrough performance' was achieved with typical terrestrial optical amplifier spacing of 100km, channel spacing of 100GHz, and by using all-Raman amplification.
The multi-service transmitter and receiver in Mintera's system employ electronic time division multiplexing for interfacing to the lower speed client signals (e.g. multiple 10 Gb/s bit streams from Ethernet switches, routers, SONET add-drop multiplexers, optical switches), Enhanced Forward Error Correction (EFEC) technology, and Mintera's (patent pending) Chirped Carrier Suppressed Return-to-Zero (CCS-RZ) modulation on the ultra long haul optical link.
Mintera says its patent protected technology will allow service providers to seamlessly upgrade their existing infrastructure to 40G while decreasing initial deployment capital expenses and lifetime operational costs
The company was launched in October 2000 and raised $26m in its first round of equity financing in December 2000.
