To exploit the full bandwidth of fiber, multiplexing combines many signals of various types — video, serial data, network data, control lines — onto one optical fiber. Two methods are used to accomplish this:
Time Division Multiplexing (TDM) – Signals are combined in dedicated low latency electronic hardware prior to conversion to optical fiber
Wavelength Division Multiplexing (WDM) – Multiple optical wavelengths are combined onto a single fiber
Both multiplexing techniques can be used separately or together to simplify optical transmission systems and reduce cost, improve reliability, reduce weight and improve performance. Multiplexed systems also simplify system upgrades since numbers of channels and channel bandwidth is a function of the electronics rather than the transmission line or components. The Moog Focal multiplexer product line accommodates the ever-increasing data rates needed for digital HD video, industrial data protocols, and high speed networks such as Ethernet.
With over 2,000 systems deployed worldwide, these field-proven, modular systems are widely adopted telemetry solutions for Remotely Operated Vehicles (ROVs) used in the offshore oil and gas industry and for other applications in harsh environments.
Leveraging our expertise with field-proven communication and networking technologies from the ROV market, we design, test and manufacture a wide range of ISO 13628-6 qualified subsea control products. We provide both standard and customized systems for critical subsea applications with options for card-level and packaged solutions.
Downtime for marine installations can be costly and hazardous. Our products support a unified condition monitoring system which helps with preventative maintenance scheduling and reduces troubleshooting times.
Since 2007, we have been providing pressure tolerant solutions for video, HD video, Ethernet and serial with thousands of products in the field. Optical transceivers are available in singlemode single fiber (bidirectional 1310 / 1550 nm) or singlemode dual fiber (18 CWDM wavelengths) up to a data rate of 4.25 Gbps.
