is used by telecommunications companies to transmit telephone signals, Internet communication and cable television signals. It is also used in other industries, including medical, defense, government, industrial and commercial. In addition to serving the purposes of telecommunications, it is used as light guides, for imaging tools, lasers, hydrophones for seismic waves, SONAR, and as sensors to measure pressure and temperature.
A PON takes advantage of (WDM), using one wavelength for downstream traffic and another for upstream traffic on a (ITU-T, typically OS2). BPON, EPON, GEPON, and have the same basic wavelength plan and use the 1490 nanometer (nm) wavelength for downstream traffic and 1310 nm wavelength for upstream traffic. 1550 nm is reserved for optional overlay services, typically RF (analog) video.
Because fiber-optic cable transmits digital signals using light impulses rather than electricity, it is immune to electromagnetic interference (EMI) and radio frequency interference (RFI). A fiber optic datalink is a communications subsystem that connects inputs and outputs (I/O) from electronic subsystems and transmits those signals over optical fiber. Their impact on everything from internet connectivity to data center operations is undeniable. Our converters are ideal for distributing signals such as IRIG (AM / DCLS), PPS or RS-232/RS-422 over long distances.
