Pure 128 channel frame type video optical transceiver
128 channel video single fiber transmission 4U shelf, equipped with 8 cards and 16 channel video cards
Product details
product description
The 128 channel integrated multiplexing video optical transmitter/receiver adopts digital encoding technology, which can achieve long-distance bidirectional transmission of 128 channel video signals through a single-mode optical fiber.
The 128 channel integrated video optical transceiver is a 19 inch 4U 17 slot rack mounted device, consisting of 8 16 channel video boards and a CWDM board. Each 16 channel video is a unit, and CWDM coarse wavelength division multiplexing technology is used to output a total of 8 wavelengths. A total of 8 video interface cards can be inserted. Easy to install and maintain, suitable for different work environments.
Functional Features
◆The 128 channel video optical transceiver uses single fiber transmission;
◆The device is a 4U 19 inch 17 slot rack, consisting of a total of 8 functional boards. The 16 channel pure video board occupies two slots, while the 16 channel video multifunctional interface board occupies three slots;
◆Easy to expand, simply add board cards, easy to maintain, simply replace board cards;
◆The data interface and video interface are equipped with lightning protection to meet the GB/T17626.5 (IEC61000-4-5) short-circuit current wave 8/20 μ s open circuit peak output voltage 6KV standard;
◆Can detect whether the remote device is powered off or disconnected when there is no light received;
◆PAL/NTSC/SECAM full standard compatibility, studio level transmission quality.
