Shortest transmission distance of optical modules
The transmission distance of optical transceiver modules is divided into short distance, medium distance, and long distance. Product Knowledge: Choosing the Right One: 🔎 Match fiber type (MMF or SMF) 🔎 Consider link budget and optical power 🔎 Watch for connector. Long distance optical modules address the needs of long-distance transmission, such as urban area network construction and synchronous fiber optic networks. Among the most common are SR LR, two terms that show up everywhere — from switch ports in data centers to uplinks between buildings. Common center wavelengths for gray optical modules include: 850 nm (with MMF): Can transmit up to 2 km at 100M rate, 550 m at 1G rate, 300 m at 10G rate, 400 m at 40G rate, and 100 m at 25G/100G/200G/400G rates.
