Why is multi mode fiber used on LANs?

Multi-mode fiber is commonly used on Local Area Networks (LANs) because it supports high data rates over short distances, making it ideal for intra-building connections. Its larger core allows multiple light modes to propagate, which is effective for transmitting data within a limited range, typically up to 300 meters. Additionally, multi-mode fiber is generally more cost-effective than single-mode fiber for these applications, making it a practical choice for organizations looking to balance performance and budget in their network infrastructure.
