Extended-Loss-Budget Pluggable Transceiver for 10G/1G compatible PON with N:1 Redundant OLT Protection

Abstract

We develop the first OLT-pluggable extended-loss-budget transceiver necessary for 10G/1G compatible PON with N:1 redundant OLT protection. This paper newly define the requirement of the OLT transceiver supporting protection by assuming an additional loss of redundant function. The average output power of 6.95/8.35 dBm and minimum receiver sensitivity of -32.02/-34.53 dBm for 10G/1G are attained, respectively. Experiments also confirm 40-km-SMF transmission with no dispersion penalties. It achieves the 36.02/35.53-dB loss budget as 10G/1G OLT transceiver, where ONU transceiver’s specification is based on 10GBASE-PR40/1000BASE-PX40, successfully meeting required loss budget for N:1 redundant OLT protection.
