A 5 Gb/s repeaterless transmission system using erbium-doped fiber amplifiers

Abstract

A fully engineered 5 Gb/s repeaterless long-span transmission system with excellent long term performance is introduced. The transmitting power from an optical power booster was +15.5 dBm with SBS suppression, and an optical preamplifier receiver provided a receiver sensitivity of -38 dBm for 10/sup -9/ BER (or -35 dBm for 10/sup -15/ BER). A Ti:LiNbO/sub 3/ external modulator transmitter allowed dispersion limited repeaterless transmission through 226 km non-DSF (a total dispersion of 4100 ps/nm).< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
