Maximum distance of optical module class
VR (Very Short Range): Transmission distance usually 0~100 meters, using multimode fiber for short data center connections. A GPON optical module is a transceiver used in GPON networks to convert electrical signals into optical signals and vice versa. To recap Optical Fiber can be divided into Multimode Fiber (MMF) and Single-Mode optical fiber (SMF). Multimode Fiber (MMF) has a core diameter, typically 50–100 micrometers, has ability to transfer multiple modes of light through the fiber core, uses lower-cost electronics (LED, VCSEL) operates at. This guide explains the principles of optical budgeting, provides actual distances per standard and data rate, and helps you calculate the range of your own installation. Le optical budget (or link budget) is the available power margin between the transmitter and receiver of a fiber link.
