Dust cap and optical transceiver

Abstract

The invention provides a dust cap which allows for performing operation test of an optical transceiver without removing the dust cap from the optical transceiver. The dust cap 100 comprises: a connector 110a having an opening on a distal end of the connector 110a, which is pressed into a transmission adapter of the optical transceiver 300; a connector 110b having an opening on a distal end of the connector 110b, which is pressed into a reception adapter of the optical transceiver 300 adjacent to the transmission adapter; a support member 140 connected with proximal ends of the connectors 110a, 110b and configured to support the connectors 110a, 110b; and an optical transmission path 130 configured to pass through the connector 110a, the support member 140, and the connector 110b in that order and to transmit light from the opening of the connector 110a to the opening of the connector 110b.
