Combined single-mode/multimode fiber link supporting simplified in-building 60-GHz gigabit wireless access

摘要

In this paper, we propose and experimentally demonstrate a simple, cost-effective hybrid gigabit fiber-wireless system for in-building wireless access. Simplicity and cost-effectiveness are achieved in all parts of the system by utilizing direct laser modulation, optical frequency up-conversion, combined single mode/multimode fiber transmission and envelope detection. Error-free transmission of 2-Gbps data in 60-GHz band over a composite channel including 10-km standard single-mode fiber (SSMF)/l-km mul-timode fiber (MMF) and 6.5-m air transmission was successfully achieved.
