24 channel video multi service optical transceiver, capable of carrying data, audio, intercom, telephone, etc E1、 Ethernet, switch quantity
Product Details
product description
This series of digital video optical transceivers adopts digital video encoding and gigabit fiber optic transmission technology to transmit multiple single and bidirectional videos, audios, data, audios, telephones, Ethernet, and switch signals in real-time, without distortion, and with high quality on single core or dual core fibers. Adopting fully digital video uncompressed transmission technology, with video and data status indicators, it can monitor the normal operation of the system. It adopts a modular structural design, and users can flexibly choose or customize configurations according to the specific situation on site. There are two structural forms available: independent desktop installation and rack installation.
This series of products consists of an optical transmitter and an optical receiver, which can simultaneously transmit 24 channels of forward video+audio, data, audio, intercom, telephone, etc E1、V.35、 Ethernet, switch quantity
