Polarization division multiplexed 4 × 10 Gbps simultaneous transmissions in 10-µm waveband and C-waveband over a 144-km-long holey fiber using an ultra-broadband photonic transport system

Polarization division multiplexing (PDM) and wavelength division multiplexing (WDM) are essential techniques for enhancing the capacity of photonic networks and facilitating the efficient use of optical frequency resources. 2 PDM × 2 WDM × 10 Gbps error-free simultaneous transmissions in the 1.0-µm waveband and C-waveband are successfully demonstrated for the first time using an ultra-broadband photonic transport system over a 14.4-km-long holey fiber transmission line.
