EPON/GPON automatic compatible repeater is my company independent research and development for EPON/GPON optical broadband access system, the optical signal is amplified again optical communication equipment. It can effectively save the OLT amount, extend the communication distance, and can greatly expand the light branch number, save fiber dosage. My company's PON OEO repeater is widely used in light of EPON/GPON long-distance transmission. Its advantage is small, low cost, security, easy to install, and implements the EPON and GPON automatically adjust.

2、Upward: support 1.25 G/s sudden signal to send and receive
3、Support 60 km 1:6 4 ODN network expansion
2.2 interface is introduced
EPON/GPON compatible type amplifier equipment, each interface specification is as follows:
1、 ETHERNET network, the device support WEB network management way, compatible with various browsers, use very convenient;
2、EPON/GPON optical interface connection way is: The direction of the ONU optical fiber connected to the ‘TO ONU’ port， The direction of the OLT optical fiber connected to the ‘TO OLT’ port, the repeater realization of downstream and upstream directions of light signal amplification;
3、the DEFAULT button is to restore factory Settings button, click the DEFAULT button, the IP address is set to factory DEFAULT address: 192.168.1.102;
2.3 The panel light:
1、UP: upward direction indicator lights, lights flashing, said not yet received the upward direction (from the ONU is sent to the OLT) signal, The light has been on said reception normal upward direction;
2、DOWN: downward direction indicator lights, lights flashing, said have not received the downside (from OLT to ONU) signal, The light has been on said reception normal downward direction;
3、ACT: the light is said received Ethernet network interface signal;
4、LINK: the light is said of the Ethernet network interface signal connection is normal;
5、WEB network IP address: can be set by the user, the default factory IP address is: 192.168.1.102
2.4 the physical properties:
1、Optical interface physical properties:
■TO OLT port receiving sensitivity ≦ - 28 DBM
