Defining a 914-X Series System

914-X Series systems are used as pairs (one remote and one console) to provide a transparent video, data and
Ethernet link over optical fiber(s). The installed optical transceivers determine the maximum optical link speed, fiber
type, number of fibers (1 or 2), and link distance. The card version sets the operational bandwidth, which is
independent from the optical data rate. The optical link uses a proprietary data protocol ensuring reliable
transmission with extremely low latency using highly efficient and dynamic bandwidth utilization.
Typically, the uplink (remote to console) and downlink (console to remote) are combined on a single fiber –
multimode or singlemode (standard) – with a passive optical coupler known as a Wavelength Division Multiplexer
(WDM). The WDM is integrated in the optical transceiver. Standard, single fiber systems operate with 1310 nm
uplink and 1550 nm downlink wavelengths. In larger systems, multiple 914-X Series stacks may be combined on a
single fiber using a Coarse Wavelength Division Multiplexer (CWDM) to take advantage of the high bandwidth of
optical fiber.
Figure 3-1 illustrates an example of a simple 914-X Series system configuration using a standard, standalone 914-
HDE motherboard, which supports the multiplexing of one (1) 3G/HD/SD-SDI channels, two (2) bidirectional RS-
232 / RS-485 / RS-422 serial data channels and one (1) Gigabit Ethernet channel over a single optical fiber. This
is the base card of any 914-X Series system.
