The 907-SPLIT 1x2 optical splitter card, shown in Figure 6-9, is used to split an optical signal for redundant
operation. Typically installed at the remote (subsea) end of a 907 system, this card splits the optical power
from a multiplexer or media converter card equally into two fiber outputs at F1 and F2. Typical loss through
the splitter is less than 4 dB, with a 1 dB level of power uniformity between the two output fibers. Usually a
fiber optic switch is included at the console to select which fiber is active. Alternatively, fibers can be manually
selected and reconnected to the console card.
The 907-SPLIT card is also available in pressure tolerant versions.

Caution: Splitters can only be used at one end of the system, as recombining signals at the far end
with another splitter will corrupt the data due to differences in the fiber delays and possibly
interference of the laser signal.
