Lumentum detailed recently its high-bandwidth coherent driver modulator (HB-CDM) that operates at a symbol rate up to 96 gigabaud (GBd).
"Lumentum is working with a decent number of network equipment makers (NEMs) on their high-performance coherent offerings using the HB-CDM component," says Brandon Collings, CTO of Lumentum.
The 96GBd device supports modulation formats from dual polarisation quadrature phase-shift keying (DP-QPSK) to 64-ary quadrature amplitude modulation (DP-64QAM) and when used with an appropriate coherent digital signal processor (DSP), the device supports up to 800-gigabit wavelengths.
