Description and application of the fiber SLC carrier system

The Fiber SLC
¹
Carder System is a repeaterless digital loop carrier that employs lightwave features for the transmission of voice and data from a telephone central office to a remote location. This paper describes the development and application of this 1.3-μm LED/p-in based system. Experience with first applications is reported along with current developments intended to increase its capacity and bring digital capability close to the customer at the DS3 bit rate (44.736 Mbits/s). Services to the customer include DS1 port capability (1.544 Mbits/s), DS2 optical paths (6.312 Mbits/s), voice, and data.
