Survivability is a critical requirement of optical communication networks that is typically addressed implementing path diversity. However, due to the elevated cost of fiber installation, this approach may prove prohibitively expensive in optical access networks. In this paper, a novel cost-efficient photonic millimeter (mm) - wave bridge is proposed, which converts passive optical network (PON) signals to radio frequency signals at mm-wave bands. The performance of the mm-wave photonic bridge is numerically tested, revealing its feasibility to transmit a 2.5-Gbps PON with {55.6 dB wireless link gain (WLG) using the 81-86 GHz band and 10-Gbps PON with {35 dB at the 102-109.5 GHz band. The effect of ber is also analyzed, showing that ber cuts closer to the optical network unit degrades more the system performance.
