When choosing between single-mode and multi-mode fiber for MPO patchcord, there are several factors to consider, such as the distance of the link, the bandwidth requirements, and the budget. Here are some guidelines to help you make the right choice:
Distance: Single-mode fiber is typically used for longer distances, while multi-mode fiber is used for shorter distances. Single-mode fiber can transmit signals up to 40 kilometers (km) or more, while multi-mode fiber is usually used for distances between 550 meters (m) to 2 km.

Bandwidth: Single-mode fiber has a higher bandwidth than multi-mode fiber, which means it can transmit more data over longer distances. If your application requires high bandwidth, such as for video streaming or data backup, single-mode fiber may be a better choice.
Cost: Multi-mode fiber is generally less expensive than single-mode fiber, so if cost is a concern, multi-mode fiber may be a better option.
Compatibility: Check the compatibility of the equipment you are using with the type of fiber you choose. Some equipment may only support one type of fiber, so it is important to ensure that your MPO patchcord is compatible with your equipment.
Future-proofing: Consider your future needs when choosing fiber type. Single-mode fiber is more future-proof than multi-mode fiber, as it can support higher data rates and longer distances.
In summary, when choosing between single-mode and multi-mode fiber for MPO patchcord, consider the distance, bandwidth requirements, cost, compatibility, and future-proofing needs of your application. If you need to transmit data over longer distances or require higher bandwidth, single-mode fiber may be better, while multi-mode fiber may be more suitable for shorter distances and lower bandwidth needs. It is also important to ensure compatibility with your equipment and consider future needs when making your decision.
