Observation of Raman Gain in Reduced Length of Bismuth Erbium Doped Fiber
Raman amplification of a 49 cm Bismuth oxide (Bi2O3) as a nonlinear gainmedium based erbium doped fiber amplifier (EDFA) is reported in new and compactdesign in near infrared spectral regions. The bismuth glass host provides theopportunity to be doped heavily with erbium ions to allow a compact optical gain fiberamplifier design by using reduced fiber length and the 1480...
متن کاملComparative performance of Raman-SOA and Raman- EDFA hybrid optical amplifiers in DWDM transmission systems
To combine the benefits and compensate for the drawbacks of different optical amplifier types, a hybrid amplifier can be composed. The authors consider two most frequently used hybrid amplifiers that can provide better performance: a semiconductor optical amplifier (SOA), and an erbium doped fiber amplifier (EDFA), both in combination with a distributed Raman amplifier (DRA). To compare perform...
متن کامل32 x 10 and 64 × 10 Gb/s transmission using hybrid Raman-Erbium doped optical amplifiers
We have successfully demonstrated a long-haul transmission of 32 × 10 Gbit/s and 64 × 10 Gbit/s over singlemode fiber of 650 km and 530 km respectively by using RAMANEDFA hybrid optical amplifier as inline and preamplifier amplifiers. The measured Q-factors and BER of the 32 and 64 channels after 650 and 530 km respectively (16.99–17 dB) and (10 -13 ) were higher than the standard acceptable va...
متن کاملDevelopment of Erbium Doped Fiber Amplifiers using Photonic Crystal Fibers as Gain Media
Erbium doped fiber amplifiers (EDFAs) are the essential components of a highly efficient, long distance optical data link. Their design has been refined to give better performance parameters. In the recent years, a new class of optical fibers known as photonic crystal fibers (PCFs) is being explored for its suitability as a gain medium in EDFA. The information regarding the progress in this fie...
متن کاملOptimal span length in high-speed transmission systems with hybrid Raman-erbium-doped fiber amplification.
We show, using nonlinearity management, that the optimal performance in high-bit-rate dispersion-managed fiber systems with hybrid amplification is achieved for a specific amplifier spacing that is different from the asymptotically vanishing length corresponding to ideally distributed amplification [Opt. Lett. 15, 1064 (1990)]. In particular, we prove the existence of a nontrivial optimal span ...
