4-channel optic video multiplexer is a miniaturized fiber transmission equipment of video, data and other service signals. It introduces advanced all-digital uncompressed technique and was tailor-made for surveillance & control market. It is able to transfer 4-channel unidirectional video, 4-channel data, 4-channel bidirectional audio. The hot swappable design makes the installation very easy and on-site adjustment unnecessary. All interfaces based on standard core circuits and optical modules are compliant with all international criteria.
1. Feature of 4-channel optic video multiplexer
SNMP network management function which can realize real time monitoring.
Video quality of broadcast-level.
Audio quality of CD-level.
Compatibility of video formats like PAL, NTSC, SECAM etc.
SMT(Surface Mount Technology) Lighting and surge multiple protection
Lossless video regeneration and repetition trucking free from electro-magnetic or radio frequency interference.
Transparent data coding and is compatible with the products of major camera manufacturers.
Advanced self-adaptive technique, no on-site electrical or optical adjustments are necessary.
Miniaturized and compact structure, very easy to install.
