What is Optical Switching?

What is an Optical Switch?

An optical switch is a multi-port network bridge, which connects multiple optic fibers to each other and controls data packets routing between inputs and outputs. Some optical switches convert light to electrical data before forwarding it and converting it into a light signal again. Other optical switches, which are called All-optical, can route and forward the light pulses themselves without any electrical conversion.

What is an All-optical switch?

An all-optical switch controls the routing between multiple optic fibers without any electrical data conversion. All-optical switches routes the entire light signal which is coming from an optical input and forward it all to an optical output without converting or altering IP level data packets. Because of not using electrical conversion, All-optical switches do not have latency, data corruption or timing jitter.

All-optical Switch Features

  • All-optical switch is a circuit switch with no packet routing
  • Does not selectively route IP packets
  • Switches data on the fiber without conversion
  • All-optical switch uses OOO switching
  • OOO switching optical input, optical switch core and optical output
  • Does not use OEO (Optical - Electrical - Optical ) conversion
  • Switches the entire light signal from one fiber to another
  • Has no timing jitter, latency or data corruption

What types of signals can an all-optical switch route?

Any wavelength that propagates through optical fiber can be transferred and routed through an all-optic switch, including Single mode signals with 1260-1675 nm wavelength and Multi-mode signals with 850 and 1300 nm wavelength. No data conversion routing method allows all-optic switches to transfer data in any rate and in any format, all-optic switches can route video, audio, data and optical sensor signals, with 400 Gbps+ bandwidth.

Why Use Fiber Switching?

Using fiber switches has many benefits over conventional copper switches. The fiber layer, used in optical switches, is mostly static. This means that optic switch cabling needs to be done only once and can be reconfigured remotely without the need for patching or manual intervention. Optical switches reduce cost, power usage, and electrical conversion delays, which create transparent paths with near, zero latency. In addition, because fiber optic switching uses management software, it maintains an inventory of cross-connects routing.
