§1.1 Introduction
EBDV series digital fiber mux (Fiber mux for short) is complete digital highspeed fiber transmission product.
Using advanced fiber communication technology, digital video technology and data communication
technology and adopting reliable large scale special integrated circuit and whole surface by decoration,
it is one of the most advanced transmission product for long, distance and highdistinguishability video
monitoring at present.
This product is made up of fiber transmitter and fiber receiver and can transmit 1-4 channels broadcasting
positive video signal, 1 channel high-speed positive and negative asynchronous data signal.
§1.2 Characteristics
² ASIC design SMT craftwork
² Complete digital fiber transmission platform and flexible configuration of different signal
² Two types: standalone, desktop; card, rack
² Independent intellectual property large-scale special-purpose integrated circuit core
² Transmit on one fiber, double fibers is also selected.
² PAL/NTSC/SECAM auto-negotiation, broadcasting transmission quality
² Provides bi-directional asynchronous data (positive and negative)
² Provides one channel asynchronous data, the transmit speed can reach more than
115.200Kbps.
² Asynchronous data are RS232/RS485/RS422/ Manchester code.
§1.3 Technical Specification
Optic fiber
Connector: FCTransmission range:
0~20Km (single-mode fiber, standard type)
0~60Km (single-mode fiber, long distance type)
0~120Km (single-mode fiber, super long distance type)
0~2Km (multi-mode fiber, standard type)
Note:
transmission range is affected by loss of optic fiber and other index, so the actual range may be different
from the above data.
