VCSEL-based, CWDM - PON systems using reflective technology for bi-directional multi-play service provision

Abstract

Orthogonal frequency division multiplexing based on radio-overfiber schemes allows the direct use of multiple, native format wireless platforms. In combination with standard baseband provision such as Gigabit Ethernet, this provides access to a wide range of services without requiring specialized end-user equipment. However, such signals have a high laser power-bandwidth requirement which may not be a good fit to the domestic environment. Here we explore the use of low-power optical components in customer premises which interface with an intermediate optical network node. Two solutions in the context of SSMF over a CWDM optical network are described, based on either reflective or direct modulation. EVMs of better than 35 dB were achieved. ©2012 Optical Society of America
