System Specification
When specifying a 914-X Series system, it is important to ensure there is enough available optical bandwidth to
support the signals and data throughput required. Moog Focal has released three versions of the 914-HDE
motherboard with pricing linked to bandwidth. This allows customers who do not require expansion cards, 3G-SDI,
or gigabit Ethernet to specify a more cost effective solution. Moog Focal can work with customers to configure a
complete optical multiplexer solution, and the following section shows signal bandwidths and sample system
configurations. This allows customers to weigh the tradeoffs between system bandwidth, cost, size and power,
while also showing the upgrade potential of any 914-X Series system.

Using the above two tables as a reference, it becomes possible to specify a full system and ensure a lossless, low
latency optical link.

How to choose the optimal 914-X Series System Architecture
1. Calculate the bandwidth of the required signals based on Table 3-2.
2. Choose the 914-HDE motherboard version based on required bandwidth. Multiple 914-X Series systems
may be required for very high bandwidth applications. Refer to Table 3-3.
3. Consider using 914-HDV2 for systems requiring more than one HD video channel.
4. Choose 914 expansion card(s) with the required number and type of interfaces required.
5. Ensure the base bandwidths for the 914-HDE and any 914-VDX cards are included with the bandwidth
calculations.
6. Verify expansion channels available vs required, refer to Table 3-1.
7. Balance expansion cards between motherboards in very large systems.
