“…Two erbium-doped fibre amplifiers were used as shown in Fig 4. Each consisted of a 15 m length of lightly-doped broadband erbium fibre pumped from both ends by 1480 nm multiple quantum well (MQW) laser diodes [11].…”

The recently-installed UK-Channel Islands No 7 cable system is a 132 km unrepeatered, twelve optical fibre, 140 Mbit /s system. In February the cable was used for a series of tests to demonstrate new transmission and receiver equipment developed at British Telecom Research Laboratories (BTRL). The paper describes first the use of erbium fibre power amplifiers to achieve two-way transmission over the system at 2.488 Gbit/s, and then the testing of a novel semi-ruggedised laser PIN receiver.

“…2. Output power from the semiconductor pump lasers was 30-40 mW in fiber [24], and the insertion loss of the interference filter-based multiplexer was typically 0.5 dB for both pump and signal. The erbium-doped fiber gave a broad-band gain spectrum [6] and the length of approximately 20 m was chosen to maximize the small-signal gain bandwidth.…”

As a result of recent advances in erbium-doped fiber amplifiers it is clear that transmission systems employing optical amplifier repeaters will outperform their electronically regenerated counterparts in many applications. For example, substantial cost savings can be envisaged when optical amplifiers are combined with wavelength division multiplexing (WDM) techniques in order to introduce additional capacity and transparency into future optical transmission networks.In this paper, we consider the requirements and practicalities of amplifier cascades for multichannel coherent transmission. We describe a four-amplifier cascade which maintains an overall noise figure of less than 13 dB across a 20 nm optical bandwidth for total input powers up to -10 dBm. A potential capacity of one-hundred WDM channels is demonstrated in a 300 km 622 Mb/s DPSK coherent transmission experiment.
