摘要：
The paper reports on the development of 90 Mbit/s optical PCM transmission equipment which is suitable to the long-haul and large capacity transmission. Repeater span 15 km could be attained by use of semiconductor laser having longer wavelength. The expandable and economical transmission system can be provided by use of the technology of three wavelengths division multiplexing.
