Contentionless MxN WSS Offers Higher Capacity

Lumentum Holdings is launching its a next-generation contentionless MxN Wavelength Selective Switch (WSS), the TrueFlex Twin 8x24. As per its maker, the component delivers low loss, removing the need for Erbium-Doped Fiber Amplifier (EDFA) arrays in many network designs while enabling add/drop port scaling to support capacity growth in CDC networks. The WSS passband filters out wideband noise delivering high performance independent of port count and relaxes complex filtering requirements on transmitters and receivers. Eliminating EDFA arrays enables the delivery of higher density, lower cost, higher reliability, highly power efficient solutions.


"As CDC networks evolve to further support super channels, the filtering requirements become more important. Lumentum's contentionless MxN WSS supports this evolution and limits the need for add/drop amplification in many applications," said Ian Redpath, practice leader, Components, Transport and Routing, Ovum.
