Passive Optical Network Uplink and Downlink Wavelengths

PON networks use different wavelengths for upstream and downstream transmission over the same fiber. The downstream wavelength is typically 1490 nm or 1577 nm, and the upstream wavelength is usually 1310 nm or 1270 nm. G...

GPON vs. XG-PON vs. XGS-PON: A Comprehensive Comparison

XG-PON (10-Gigabit Passive Optical Network), defined by ITU-T G.987.x, is the next step in PON evolution. It provides a downstream bandwidth of 10 Gbps and an upstream bandwidth of 2.5
