E1, V.35, Ethernet Fiber Modem

详情

Our E1 fiber optic modem is designed to provide fiber connection for E1 equipment. It includes a E1 Line Interface Unit that provides E1 line driver/receiver, data/clock recovery, jitter attenuation, AMI/B8ZS/HDB3 encoding, AIS (Alarm Indication Signal) detection, BPV (Bi-Polar Violation) detection, and loop back mode. It offers two modes of Loopback for testing the connection integrity. In the Local Loopback mode, the modem loops back the received E1 signal. In the Remote Loopback mode, the modem sends loopback codes to cause the far-end modem to loop back the received optical data.

Ethernet Fiber Modem provides *4K~2M bandwidth data transmission channel for Ethernet over fiber optic cable, it is suitable for many situations, such as LAN expansion, networks isolation, WAN access, it can connect Ethernet to telecom transmission network, special network or WAN.

V.*5 fiber Modem converts V.*5 electrical signal into optical data stream for transport over single mode or multimode fiber optic cables. At the opposite end of the fiber, the optical stream is converted back into electrical signals of the appropriate interface such as G.**3 & V.*5. This fiber optic modem extends the transmission distance up to more than **0Km. The frame format of is frame/unframe for E1, so it can be used to transmit E1 signal of frame video or unframe video.
 

Our Multi-Channel Optical Modemis an all-in-one converter solution that is equipped with multiple interfaces to handle conversion between RS***2 to RS***2/**5 and serial to fiber communication. It can be used for RS***2/**2 point to point connections and RS***5 multi-drop applications for transmitting signals up to *0KM, and is the best solution for applications where transmission must be protected from electrical exposure, surges, lighting or chemical corrosion in the industry environment. Note that the RS***2 and RS***2/**5 interfaces can not be used simultaneously when converting to optic fiber mode.


Our unmanaged industrial ethernet switch provides 2 uplink redundant **0Mbit/s optic ports. The uplink redundant fiber optic interface can be used to build a self-healing fiber optic ring network.

Our Multi-channel dual loop self-recovery fiber multiplexeris a bi-directional RS***2 to Dual Loop Fiber converter. This innovation is the fruit of today technology. It extends the RS***2 data transmission distance up to *0 KM in single mode. The dual Fiber channel also provides redundant self recovery capability which in the event that one channel fails, the other channel will automatically takes over to eliminate the system down time or interruption. The converter also has built-in V+ and V- reverse power protection which will adjust its voltage level automatically.
