2019 International Conference on Computer Communication and Informatics (ICCCI), 2019
(OAF) All-Optical Amplify-and-forward Relaying technique is exploited to amplify, filter and forward the weak signal. It is also considered to be an easy method to increase the communicating distance of FSO systems [1]. The main drawback of existing relaying node is degradation of system’s bit error ratio (BER) and the value of optical signal to noise ...

Performance characteristics of dual-pumped hybrid EDFA/Raman optical amplifier
Applied Optics, 2015This paper suggests a hybrid amplifier using an erbium-doped fiber amplifier (EDFA) and Raman amplifier (RA) with dual-pump configuration. This hybrid EDFA/RA optical amplifier (HOA) is dual pumped. The EDFA is forward biased with 980 nm while the RA is reverse biased with 1450 nm in the dual-pump configuration.

Link control protection in cascades of optical Hybrid Amplifiers (EDFA + DFRA)
2012 IV International Congress on Ultra Modern Telecommunications and Control Systems, 2012In this work the power transient control in cascades of Hybrid Amplifiers (HAs) is investigated. Two hybrid configurations are considered: a backward pumped DFRA preceding an EDFA and a forward pumped DFRA ahead of an EDFA. In both cases the EDFA in forward pumped.

Hybrid optical switch using passive polymer waveguides and semiconductor optical amplifiers
Journal of Lightwave Technology, 2000Optical switching can be performed by using optical amplifiers combined with a passive waveguiding network. Recently, most of the effort in optical amplifier switch modules have been focused on monolithic switches in which the entire device is fabricated on an InP substrate together with the semiconductor optical amplifiers (SOA's).

PERFORMANCE EVALUATION OF HYBRID OPTICAL AMPLIFIER IN FIBER OPTICAL COMMUNICATION SYSTEM
13th International Conference on Fiber Optics and Photonics, 2016In this paper, we investigated the post, pre- and symmetrical power compensation methods consisting of hybrid optical amplifiers i.e. RAMAN-EDFA for different data formats such as non-return to zero (NRZ), return to zero (RZ). The results are compared in terms of bit error rate, Q-factor and output power.
