High-capacity transmission over polymer optical fiber

Polymer optical fiber (POF) is a promising transmission medium to provide broad-band telecommunication services within the customers premises. POF offers several attractive features for data transmission such as broad bandwidth and low cost for in-house, access, and local-area-network (LAN) applications. This paper presents a review on optical transmission systems using POF and their enabling technologies. A summary is given of experimental data links with record capacity over record transmission distances. To conclude, we discuss trends for further development and research.

Cost-effective up to 40 Gb/s transmission performance of 1310 nm directly Modulated lasers for short- to medium-range distances

This paper presents successful 20 and 40 Gb/s potentially low-cost transmission experiments using 1310 nm directly modulated distributed feedback lasers (DMLs) in the very-short- to medium-range distances. This paper will recommend operating conditions for error-free transmission at these bit rates and distances. Pattern dependencies are identified. General characteristics of direct laser modulation are confirmed by dedicated simulation software and experiments. Unknown laser parameters needed to solve the rate equations are estimated by a given method based on measured and calculated small- and large-signal DML responses.

Experimental assessment of 1.3 μm telecommunication systems incorporating a praseodymium doped fiber amplifier (PDFA)

We have investigated the system performance of an experimental Praseodymium Doped Fibre Amplifier (PDFA) in an optical transmission system operating at 1.3μm. Experimental evaluation of the PDFA, based on Bit Error Rate (BER) measurements, is presented for the PDFA in copropagating and bidirectional configurations as a function of both wavelength and optical input power. The performance is analysed for both NRZ and RZ modulation format at a bitrate of 10 Gbit/s. The polarisation dependency of the PDFA is less than 0.2 dB. The results of an experimental analysis of the PDFA in an optical recirculating loop are shown for a NRZ modulated pseudo random data stream at 622 Mbit/s. A total span of approximately 2000 km is covered. Furthermore, the results of transmission experiments using the optical circulating loop at 10 Gbit/s are presented.
