Solution for Single Mode Fiber (SMF) Reaches up to 300km

Vitesse delivers first 10Gbps NRZ 300km solution for uncompensated SMF

With rising demand to upgrade metro networks to 10Gbps without using dispersion compensation fiber (DCF), Vitesse meets the challenge with a suite of ICs ideally suited to this application. At the center of this solution is Vitesse’s single port electronic dispersion compensation (EDC) CDR, the VSC8240, and Vitesse’s 10Gbps TIA, VSC7878. Together, they provide superior performance in environments with heavily degraded optical signal-to-noise ratio (OSNR), a critical issue for high-speed optical links. Several other Vitesse devices complete the solution, all benefiting from Vitesse’s leadership in 10Gbps transmission.

VSC8240:Single Port 10 Gbps Bidirectional Electronic Dispersion Compensation (EDC) CDR ?Supports SR/LR/LRM module applications
