Optical Carrier level 3: 155.52 Mbps.
A high-speed telecommunications link supporting a speed of 155 megabits (Mb) per second.
Series of physical protocols (OC1, OC2, OC3 and so on), defined for SONET optical signal transmission. OC signal levels put STS frames onto multmode fiber optic lines at a variety of speeds. The base rate is 51.84 Mbps or OC1. Each signal level thereafter operates at a speed divisible by that number. OC3 runs at 155.52 Mbps. PCR (Peak Cell Rate) In cells/sec, the cell rate that the source may never exceed.
OC stands for "Optical Carrier" the speed of fiber optic networks. OC3 is equivalent to 155.52 Mbps
Our OC3 service is a super high speed service with 155 megabits per second (compare with a T1 at 1.5 megabits per second, or T3 at 45 megabits per second). OC3 is equivalent to 100 T1s or three T3s.
Optical Carrier Level 3 is a fiber optic connection that can handle 155Mbps, often used for the 155 Mbps ATM protocol.
An optical interface to ATM operating at 155 Mbit/s.
This is the abbreviation for Optical Carrier level 3, an Internet transmission method capable of speeds of 155.52Mbps.
A high-speed digital transmission capability of 155 Mbps. Compare DS3, T1, ISDN.
Acronym for Optical Carrier 3, a transmission rate standard for fiber optic telephony or data communications circuits. OC3 operates at 155 Mbps speed and is part of the SONET hierarchy.
A type of leased line that downloads at 155Mbps.
An ATM/SONET/SDH based optical transport operating at 155Mbits/second.
Optical Carrier 3 An optical fiber line carrying 155mbps; a U.S. designation generally recognized throughout the telecommunications community worldwide.
A protocol for communications over a high-speed optical network.
Fiber optic connection capable of transfering data at 155.52 Mbps.
Short for Optical Carrier, used to specify the speed of fiber optic networks conforming to the SONET standard. The following table shows the speeds for common OC levels. OC Level Speed OC-1 51.85 Mbps OC-3 155.52Mbps OC-12 622.08Mbps OC-24 1.244Gbps OC-48Gbps 2.488Gbps
n. Short for optical carrier 3. One of several optical signal circuits used in the SONET high-speed fiber-optic data transmission system. OC3 carries a signal of 155.52 Mbps, the minimum transmission speed for which SONET and the European standard, SDH, are fully interoperable. See also SONET.
Network line with a transmission speed of 155.52 Mbps (payload of 150.336 Mbps) using fiber optics. For SDH interfaces, OC3 is also known as STM1.
