Koncent
announces its newly developed
high performance isolator series
Oct 18, 2001
Koncent Communication, Inc. , a leading optical component manufacturer, announces
its newly developed high performance isolator series. Koncent new
isolator series features ultra-high isolation with isolation as
high as 70dB; ultra-low insertion loss with insertion loss as low
as 0.25dB; ultra-low PMD with PMD as low as 0.02ps, while maintaining
Koncent's consistent high quality isolators with competitive prices
in the market.
Koncent
ultra-high isolation isolators are manufactured with Koncent's patent
pending technology. The isolator provides significant improved performance
against the traditional dual stage isolator with isolation of 50-58
dB at central wavelength and 45dB over 60nm bandwidth. Koncent's
new isolators have extremely high isolation at the central wavelength
and flat isolation spectral curve, i.e. over 65dB isolation at central
wavelength and higher than 55dB isolation over 60nm bandwidth.
Koncent
ultra-low loss isolators take advantage of its proprietary collimating
lens technologies, featuring ultra-low insertion loss of 0.25dB
for single stage isolators.
Koncent
ultra-low PMD isolators are based on Koncent's proprietary technology
on PMD compensation and PMD control. Koncent ultra-low PMD isolators
have less than 0.02ps PMD against the traditional PMD compensated
isolators with 0.05ps PMD.
EDFA,
Raman amplifier, and broadband light source have very strict requirements
for isolator on bandwidth, isolation, PMD, and insertion loss. Koncent's
high performance isolator family can meet and exceed the requirements
for EDFA and Raman amplifiers designed for the next generation optical
networks.
