NeoPhotonics has begun sampling its CFP2-ACO, a pluggable module for metro and long-haul optical transport.
The company demonstrated the CFP2-ACO module transmitting at 100 gigabit using polarisation multiplexed, quadrature phase-shift keying (PM-QPSK) modulation at the recent OFC show. The line-side module is capable of transmitting over 1,000km and also supports PM-16QAM that doubles capacity over metro network distances.
The CFP2-ACO is a Class 3 design: the control electronics for the modulator and laser reside on the board, alongside the coherent DSP-ASIC chip.
At OFC, NeoPhotonics also demonstrated single-wavelength 400-gigabit transmission using more advanced modulation and a higher symbol rate, and a short-reach 100-gigabit link for inside the data centre using 4-level pulse-amplitude modulation (PAM4) signalling.
