Is there a Limit to SM fibre?
"Single-mode fibre (SMF) has several advantages, but it also comes with some limitations:
Distance: While single-mode fibre can transmit data over long distances (up to 200 km or more with the right equipment), the actual distance can be limited by factors such as signal attenuation and the quality of the fibre and connectors.
Cost: Single-mode fibre components and equipment tend to be more expensive than those for multimode fibre. This includes the cost of transceivers, which need to be more precise.
Installation and Handling: Single-mode fibre requires tighter tolerances for alignment due to its smaller core diameter (about 9 micrometers). This makes it more challenging to install and handle compared to multimode fibre.
Bandwidth: While single-mode fibre supports higher bandwidths over longer distances, the actual bandwidth can be limited by the equipment used and the specific application.
Despite these limitations, single-mode fibre is widely used for long-distance and high-speed data transmission due to its superior performance in these areas."
