1. A dual gigabit passive optical network small form-factor pluggable—DGPONSFP—optical module configured to be incorporated in a small form-factor—SFP transceiver host of a gigabit passive optical network line terminal—GPON-OLT—characterized by comprising:
a case configured to house:
two bidirectional optical subassemblies—BOSAs—, wherein each BOSA is configured to provide connection to a GPON-OLT; each of the BOSAs comprising an SC ferrule adapted to provide connection to an SC optical fiber connector;
a control unit comprising connection means, adapted to provide connection to each BOSA, and a microcontroller comprising processing means configured to control an operation of each BOSA; and a high-speed electrical interface—HSEI—adapted to provide connection between the microcontroller and a SFP transceiver host where the DGPONSFP is incorporated,
wherein the HSEI is configured to provide connection to the SFP transceiver host where the DGPONSFP is incorporated by means of a port connector including only twenty pins and wherein a single pin of the twenty pins is configured to both disable transmission and to measure an optical input power on receivers of the BOSAs.
