FMO-4ETH-L

ETH fiber modem is to modulate 10/100Base-T ETH signal to single or multi-mode fiber, its data transmit rate ranging 64kbps to 2,048kbps, its fiber wavelength and connection to optional, is suitable for transmitting inner band management channel in different fiber line, and can let the same fiber line of transmit data be used for monitoring and controlling the local or remote devices with noninterference.

1.1Function

ETH fiber modem is to modulate 10/100Base-T ETH signal to single or multi-mode fiber, its data transmit rate ranging 64kbps to 2,048kbps, its fiber wavelength and connection to optional, is suitable for transmitting inner band management channel in different fiber line, and can let the same fiber line of transmit data be used for monitoring and controlling the local or remote devices with noninterference.

ETH fiber modem can be used as a local device and connect with E1 Fiber MODEM. E1 interface of E1 Fiber MODEM can connect with ETH bridge by SDH kind device, to realize the function that ETH bridge monitors the end node ETH fiber Modem directly.

 

1.2 Character

² Based on self-copy right IC;

² Realize the function: local monitor remote in long distance;

² provide 2 types of clock: fiber reconvery clock, master clock;

² Ethernet interface 10M/100MEthernet port supports full/half duplex, support VLAN proposal;

² Ethernet support AUTO-MDIX;

² Provide loop-function: Fiber local loop back by itself , Ethernet loop back by itself;

² Ethernet monitor can reset by itselfit won’t die;

² Local ETH transmit rate can follow remote, realize  long distance rate adjust function;

² Fiber line rate is N*64k, range from 64K to 2048K adjusted;

² Have PBRS Code testing functionand could be used as a 2M error code device;

² Perfect light indicate function, real time clue on data transmit state;

² ETH port offers receive and send frame counter, error receive frame counter;

² SNMP function for optional.
