MAX3665 622Mbps, Ultra-Low-Power, 3.3V Transimpedance Preamplifier for SDH/SONET ________________General Description
... The ITU/Bellcore specifications for SDH/SONET receivers require a link sensitivity of -27dBm with a bit error rate (BER) of 10-10. There is an additional 1dB power penalty to accommodate various system losses; therefore, the sensitivity of a 622Mbps receiver must be better than -28dBm. Although seve ...
