Product Code : SCL-EELE-13242
Indian Lab Suppliers supplies the Advanced Fiber Optic Communication Trainer (Product ID: 13242) as part of its electronics engineering lab equipment range. It is an advanced fibre optic trainer for digital communication: PCM voice, 16-channel time division multiplexing, Manchester coding, bit error rate and eye pattern.
Quick Answer
Voice from two telephone handsets is coded by an A-law PCM codec chip, and 16 channels of 64 kbit/s are time-division multiplexed into a 1.024 Mbit/s stream with two user-selectable 8-bit frame markers in alternate frames. The stream is Manchester coded and sent over plastic fibre on a 950 nm infrared or 660 nm red LED to a phototransistor or TTL-output detector. A 16-bit switch-selectable PRBS generator (32, 64 or 128 kHz clock) and a white-noise source (0–5 Vpp) feed bit error rate and eye pattern experiments. RS-232 ports give PC-to-PC links at up to 115.2 kbaud, and 8 switched faults and 45 test points support fault-finding. The bit error counter is described as 10-bit with LED indication up to 255; please confirm the counter range and the mains input at quotation.
