NeoPhotonics begins sampling 8x16 multicast switch modules

NeoPhotonics has begun sampling a Twin 8x16 multicast switch (MCS) module with an integrated amplifier array for use in high performance colourless-directionless-contentionless (CDC) networks.

The 8x16 MCS can drop channels from any of eight different directions through any of 16 different ports without contention, even if identical wavelengths coming from different directions are dropped at the same time. An optional 17th port is available for network monitoring and control. The MCS modules also have a “twin” circuit to perform the equivalent add functions.

This new MCS joins the NeoPhotonics family of multicast switches, which are available in 4x4 and 4x16 configurations, and are currently in volume production.

NeoPhotonics multicast switches are designed to be used in a next-generation reconfigurable optical add-drop (ROADM) node to direct any wavelength to any port (colourless), accept input wavelength channels from multiple different directions (directionless), and be able to drop two identical wavelengths from different directions through the same switch (contentionless), thereby increasing network flexibility and efficiency.

Beginning with Verizon in 2015, network operators are transitioning to a CDC architecture in order to eliminate wavelength blocking, increase network utilisation, enhance software control and future-proof current deployments. Deployments of CDC networks are expanding worldwide with deployments in Europe and now in China.

 “The 8x16 MCS module represents a significant step in providing CDC switching capability for core metro and long-haul networks for carriers worldwide,” said Tim Jenks, chairman and CEO of NeoPhotonics. “These products depend on our advanced hybrid photonic integration capabilities and combine arrays of splitters, switches, taps, monitors and amplifiers integrated together to offer superior performance, reliability and stability, and are scalable to large dimensions.”

This new MCS will be displayed in NeoPhotonics’ booth #3017 at the OFC 2017 exhibition in Los Angeles, California, on 21–23 March.
