Networking Equipment

Design and implementation of DWDM optical network equipment (such as Transponders) may help reduce latency. XKL spends a great amount of engineering time to design network equipment with an Extremely-low Latency, measured in nanoseconds (a nanosecond, or ns, is 1000 faster than a microsecond), and without interaction with the data packets. Absence of OSI layer 2, 3, or 4 internal attribution, data can get from ingress LAN port to the DWDM line port of an XKL transponder, such as the DQT10, in around 20ns (nanoseconds). If any layer 2 switching was in the device, the latency would increase to at least 5µs* – an increase of 250%. Reducing equipment latency is the fastest and most cost-effective method to reduce overall network latency.

* Typical latency of a 10Gb Ethernet switch is 5µs to 50µs
