Abstract

Coding is routinely used in microwave links to improve bit error rate (BER) performance and has frequently been suggested as a method to improve the performance of an optical ISL. We report here on investigations of an optical ISL using rate 7/8 BCH coding (128, 112). When the noise equivalent angle (NEA) is above about 0.4 microradians for the links studied, the numerical calculations showed that the gain due to coding would be much less than calculations based on the average BER. For larger NEAs, coding could result in a degradation of the link.
