payload with the 1.244-Gb/s label was demonstrated. The results showed small power penalty as much as 0.2 dB in payload transmission, which arises from crosstalk with the label, and the CS-SH-SCM labeling technique showed increased capability for multiple-span transmission of the payload with successive label swapping.

Conclusion: We have confirmed that the temperature-coeficient of the average dispersion of a ZDF transmission line is 100 times smaller than that of a conventional DSF. Temperature-independent 80GbiUs OTDM transmission using the 168km ZDF transmission line has been successfully demonstrated. No penalty was observed for the ZDF transmission line over a temperature range of 50°C without adaptive dispersion equalisation while the penalty for 151 km DSF transmission was 4.1 dB.

Applications of non-blocking large-scale optical switches based on three-dimensional micro-electro-mechanical system (3D-MEMS) technology with small size and low power consumption are described for fiber-based broadband access networks. The low-loss and fast-switching 3D-MEMS switches offer remotely reconfigurable and automated operational solutions for access networks such as fiber management, preventative maintenance, monitoring, testing, and troubleshooting of a large number of end customers. Furthermore, the wavelength, data rate, and protocol-transparent nature of 3D-MEMS switches results in a future-proof optical distribution network design for future higher speed and higher capacity wavelength division multiplexing overlay upgrades over the passive optical network (PON). We show that large-scale 3D-MEMS switches deployed in PON environments can offer over an order of magnitude in capital and operational savings in comparison to manual patch panels (in deployed fiber hardware, real estate, and manual labor) with minimal impact on the overall network design.
