2138am—Suncity—For the bettor

The function of TBC-6103 series 10/100 Base-T Optical Fiber MODEM is to directly modulate a 10/100Base-T Ethernet data to single-mode or multimode optical fiber, and users can choose data transmission rate from 64Kbps to 2048kbps.

10/100Base-T Optical Fiber MODEM can be used as a user terminal device and E1 optical fiber MODEM connection. The E1 interface of E1 Optical Fiber MODEM can be connected with the Ethernet bridge through SDH and other equipment, and Ethernet bridge can directly monitor no-node Ethernet fiber Modem. It can be used as a relay transmission device for the local network, and is especially suitable for the optical fiber terminal transmission equipment and renting equipment as the base station of the mobile communication network. The equipment is small in size, light in weight, compact in external structure, convenient in installation and maintenance, good in transmission quality and reliable in operation.
