Studio Technologies Model 400-6T/6R Provides both electrical-to-optical (E2O) conversion (6 SD/HD/3G SDI inputs to 2 single-mode optical outputs) and optical-to-electrical (O2E) conversion (2 single-mode optical inputs to 6 SD/HD/3G-SDI outputs). BNC SDI input, loop through, and output connectors (24 total); ST optical input and output connectors (4 total).
The Model 400 SDI-Over-Fiber Transport System is a high-performance, cost-effective, rack-mount solution for distributing digital video signals over short and medium distances. The system is compatible with all common broadcast serial digital video formats and is suitable for use in remote trucks, live-event video distribution, and fixed links associated with broadcast and production facilities.
The back panels include connections for AC mains and DC power, ST or SC (optional) optical connectors, BNC connectors, and an RJ45 jack for the Ethernet interface.
SDI input signals can be SD (270 Mb/s), HD (1.485 Gb/s), or 3G (2.97 Gb/s). 3G signals can be in either Level A or Level B format. The inputs also support video signals in the DVB-ASI (270 Mb/s) format. Each of the Model 400's SDI input channels is independent, allowing any combination of rates/formats to be transported.
Associated with each Model 400 SDI input channel is a re-clocked and buffered loop-through output. These can be extremely useful, allowing a signal source to be routed to another input on the Model 400 or a related piece of equipment.
Dual Power Capability
Model 400 units allow an AC mains source of 100-240 V, 50/60 Hz to be directly connected. They can also be DC powered using a 10-18 volt source that is connected via a broadcast-standard 4-pin XLR connector.
If both AC and DC power sources are connected to a Model 400, the unit will be powered by the AC mains supply. Only if the AC mains source fails will a load be placed on the DC source. This allows a source of DC, typically a battery pack, to serve in a backup capacity. With this arrangement normal SDI-over-fiber transport operation can continue even if AC mains power is lost.
