System Specification
When specifying a 914-HDE system, it is important to ensure there is enough available optical bandwidth to
support the signals and data throughput required. Focal Technologies has released three versions of the 914-
HDE 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. Focal Technologies 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-HDE 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.
