Optical transceiver device

An optical transceiver device for connecting separately a first, a second optical network equipment and an in-line equipment to establish an optical fiber network, and guarantee normal network communication between said first and second optical network equipment, including:

• a device housing;
• an optical transceiving component having a first optical transceiving port and a second optical transceiving port for connecting separately said first, second optical network equipment to perform delivery of optical signal;
• an O/E conversion substrate having an electrical signal port, and a first O/E converter unit and a second O/E converter unit, said electrical signal port being exposed to a first location of said device housing for connecting electrically said in-line equipment for delivery of electrical signal;
• said first, second O/E converter unit being for converting received optical signal into electrical signal, or converting received electrical signal into optical signal;
• an optical switching switch connecting separately with said first, second optical transceiving port and first, second O/E converter unit;
• and
• a switch control substrate connecting electrically with said optical switching switch, having a control signal port, said control signal port being exposed to a second location of said device housing for connecting electrically said in-line equipment to receive the control signal of said in-line equipment for said optical switching switch, said switch control substrate causing running state of said optical switching switch to change according to the control signal for said first, second optical transceiving port to communicate separately with the optical signal of said first, second O/E converter unit;
• or for the optical signal of said first, second optical transceiving port to communicate in a situation without accessing said in-line equipment.
