OC-3

An OC-3 is a high-capacity optical fiber communication line used by telecommunications providers. It can transmit data at a rate of approximately 155 megabits per second, which is suitable for large organizations or internet backbones. The "OC" stands for Optical Carrier, and the number indicates the level of capacity; OC-3 is one step below OC-12. It uses light signals through thin glass fibers to send data quickly and over long distances with minimal loss. OC-3 connections are essential for supporting extensive internet traffic, enterprise networks, and data centers.
