GPON – Gigabit Passive Optical Network :: An introduction

Gigabit Passive Optical Network (GPON) is a high bandwidth shared fiber access technology The following diagram shows the architecture of a basic two wavelength GPON network, which is probably the most common implementation. The downstream wavelength is 1490nm and transmits data at 2.488 Gbps. The upstream wavelength is 1310nm and transmits data at 1.244 Gbps. […]
