An in-service supervisory repeaterless bidirectional wavelength-division-multiplexing (WDM) transmission system using optical fiber amplifiers is demonstrated for the first time. The system supervision by an optical time domain reflectometer (OTDR) is achieved without degrading the 2.5 Gb/s service over a bidirectional six-WDM-channel 200-km single-fiber link, Negligible system penalties of dispersion and counter-directional transmission crosstalk are observed.

An in-service supervisory wavelength division multiplexing (WDM) transmission system is demonstrated for the first time. Simultaneous fault location and EDFA status-monitoring are achieved without degrading the 2.5 Gb/s service in a five-EDFA, 365-km, four-WDM-channel system.

A wavelength-division-multiplexed optical-time-domain-reflectometry (OTDR) supervisory technique is experimentally demonstrated in a 200-km transmission system. The technique can simultaneously achieve in-line EDFA performance monitoring and diversity protection, and fault location in optical fibers.

In this paper, we investigate various technology aspects in fiber-to-the-microcell systems. Background studies on radio propagation environment and system operations are provided first. The fundamental linearity characteristics of a directly and externally modulated optical links are analyzed next. An overall comparison between the two types of optical links, and system requirements among all types of wireless systems (from macrocells to picocells) are presented. Future research and development directions are also suggested.

In-service WDM-based supervisory transmission in four/five EDFA-repeater 375km/365km systems is demonstrated. Simultaneous EDFA status-monitoring and fibre fault location are achieved without degrading the 2.5Gbit/s service.

This paper examines optical-time-domain-reflectometry (OTDR) pulse distortion due to transient gain compression in a saturated erbium-doped fiber amplifier (EDFA) and the resultant effect on testing long-haul optical fiber systems.
