D.3 Fiber-Optic Converter (for ROV Installations)
For LCU to processor cable lengths in excess of 100 meters, a fiber-optic link is
required. This bidirectional link can run over a single-mode fiber (where cable lengths in
excess of 40 km are possible). The performance of a fiber-optic link is highly dependent
on the quality of the link, the number of connections, and the end-to-end optical loss.

Figure 74: Typical ROV Installation
RESON offers a converter which resides in a customer-provided pressure housing and
converts the electrical output from the LCU to an optical signal. At the surface, a second
converter is used to convert the optical signal back to electrical before routing into the
processor.
