Abstract
A receiver circuit for a LAN electro-optical interface includes a high pass filter connected between the optical signal receiving element and the standard ECL line receiver. The high pass filter removes noise from the signal output by the optical signal receiving element, thereby reducing the bit error rate of the system and/or increasing the effective sensitivity of the system, enabling the signal transmission distance to be increased.
