Model 400A-6T Provides electrical-to-optical (E2O) conversion of 6 SD/HD/3G-SDI inputs to 2 single-mode optical outputs. BNC input and loop through connectors (12 total); ST optical output connectors (2 total).
The Model 400A SDI-Over-Fiber Transport System consists of single-rack-space (1U) units that are factory configured from among eight available choices. The broad range of configurations allows the needs of specific applications to be directly supported. For example, the Model 400A-12T is a 12-channel electrical-to-optical (E2O) unit, while the Model 400A-12R is a 12-channel optical-to-electrical (O2E) unit. Another example, for "transceiver" applications the Model 400A-6T/6R provides six channels of electrical-to-optical (E2O) and six channels of optical-to-electrical (O2E) transport. The front panel of each unit features a day-/night-readable backlit display, menu navigation buttons, status LEDs, and power on/off switch. The back panels include connections for AC mains and DC power, ST optical connectors, BNC connectors, and an RJ45 jack for the Ethernet interface.
The Model 400A System uses a novel hardware implementation to transport up to 12 SDI signals over four single-mode optical fibers.
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 400A's SDI input channels is independent, allowing any combination of rates/formats to be transported.
Associated with each Model 400A SDI input channel is a buffered loop-through output. These can be extremely useful, allowing a signal source to be routed to another input on the Model 400A or a related piece of equipment.
Model 400A 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 400A, 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, such as 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.
The Model 400A has a management web server that allows the user to monitor system status through any web-enabled device such as a personal computer or smartphone.
Its status screen lets a user or supervisor check for the presence of AC and DC power sources as well as individual SDI input channel status, signal rate, and whether the optical transmitters are enabled. The optical output power of each electrical-to-optical (E2O) channel is reported directly in dBm. The optical receive power (in dBm) of each optical-to-electrical (O2E) channel is also displayed. This is a particularly useful feature for remote system troubleshooting.
The web management server also provides a configuration menu, allowing a variety of monitoring parameters to be set. These include alarms for loss of AC or DC power, over-temperature, and low optical transmit and receive levels. Additional menu screens provide access to network IP address and front-panel display configurations.
While the Ethernet-accessed monitoring and configuration functions enhance the utility of the Model 400A they are not necessary for SDI-over-fiber transport operation. Model 400A units will deliver reliable, high-quality performance with no other user actions except for making SDI-over-coaxial cable, fiber, and power connections. All back-panel connectors are clearly labeled for simple, fast, and intuitive use. The front-panel display provides direct access to the unit's most important status information. Updating the operating software can be easily performed using a standard USB flash drive.
