a host device having a first housing, a first optical connector arranged inside the first housing, and an electrical connector arranged inside the first housing; and
a light-emitting device having a second optical connector optically connected to the first optical connector, an electrical plug into which the electrical connector is inserted for electrical connection there-between, and a second housing accommodating the second optical connector and the electrical plug and inserted into the first housing,
wherein:
the second housing has a latch structure latched onto the first housing when inserted into the first housing,
the second optical connector has a guide hole separate and distinct from the electrical plug,
