CyOptics modulator used in Bandwidth9's 600km-reach tunable transmitter
17 December 2002 -- Indium phosphide (InP) based optical component developer CyOptics Inc has provided key technology to Bandwidth9, a manufacturer of VCSEL-based tunable laser transmission products, for the development of a highly compact, tunable, extended reach transmitter.
Bandwidth9's MetroFlex G2 transmitter combines CyOptics EAM2010 amplified electroabsorption modulator within a cost-effective, fully integrated laser system that provides uncompensated reach beyond 600km at 2.5Gbit/s.
"Wide tunability of a VCSEL, combined with the extended reach of an amplified EAM, enable a universal transmitter module that can support any ITU channel and any reach," said Vladimir Kozlov, senior analyst at RHK Optical Components.
CyOptics EAM2010 amplified modulator is a monolithic InP-based device that provides extended-reach transmission at data rates up to 10Gbit/s. Unlike standard modulators that attenuate incoming light, the EAM2010 includes built-in amplification, enabling use with low-power light sources. Also, it has integrated power monitoring and allows dynamic control of transmitter output power.
