Abstract
We investigate the use of uncooled lasers in an optical fiber transmis sion system employing quadrature-phase-shift keyed (QPSK) signals on s ubcarriers. The BER of a 2Mb/s QPSK channel is measured in a system co ntaining 60 subcarriers. Error-free performance (BER < 10(-9)) is achi eved over a wide range of modulation depths. This demonstrates that th ese inexpensive lasers can be used in multi-channel digital systems.
