Abstract :
An experimental passive optical network that demonstrates the integrated delivery of telephony and broadband services to a variety of business and residential customers over a typical local loop is described. Telephony is provided over a 112-way split at 1300 nm, and broadband services (asynchronous transfer mode and single-channel video at 155 Mb/s, and 2.2 Gb/s 32-channel video) are provided over a 28-way split. Two approaches to the addition of broadband services are used: coarse-grained WDM (wavelength-division multiplexing) with 20-nm channel spacing in the 1300-nm window, and high-density WDM with 1-nm spacing in the 1500-nm window. Optical technology solutions are described for providing different levels of service to various customer types, including a single-mode wavelength multiplexer with 1-nm channel spacing, a hybrid integrated demultiplexer/receiver with 20-nm channel spacing, and a tunable optical filter with 0.6-nm FWHM (full-width at half-maximum) bandwidth
