Xtera launches flex-rate channel card for 100G/100G+

Xtera Communications has launched its new flex-rate card, a next-generation coherent 100G/100G+ channel card to meet today’s and tomorrow’s ever-growing bandwidth demands.

The new card combines high transmission performance with multiple levels of flexibility in optical networking, including selectable wavelength to operate on either fixed or flexible optical grid and programmable signal protocols on the client side, and programmable modulation format (QPSK, 8QAM, or 16QAM), optical channel rate and spectral efficiency on the line side.
