What is the bandwidth for OC 1?

51.84 Mbit/s
OC-1 is a SONET line with transmission speeds of up to 51.84 Mbit/s (payload: 50.112 Mbit/s; overhead: 1.728 Mbit/s) using optical fiber.

What is OC192?

OC192 is an optical carrier (OC) that can handle 192 DS3s. A DS3 is a 45 Mb/s signal that can carry internet data or it can carry 28 T1s, voice or data, and 28 T1s is equal to 672 phone calls. In other words, an OC192 is a fiber optic system that can carry 192 DS3’s, which is 5376 T1s or 129,024 voice calls.

How fast is OC12?

An OC12 is a type of high-speed dedicated circuit. The OC12 transmits data at a speed of 622 Mbps. It is a large group of circuits that is equivalent to 4 OC3’s or 1344 T1s. The term OC stands for Optical Carrier.

What are OC lines?

OC = Optical Carrier (OC lines), and the transmission speed is defined in the SONET specification. OC defines transmission by optical devices, and STS is the electrical equivalent.

What is the highest OC level?

OC-1 service is the equivalent of DS3 or T3. It provides 672 voice channels (or 64K data channels) and runs at 52 Mbps to include the extra bits needed for the optical service. The highest OC level you can get at present is OC-768 which runs at 39,512 Mbps or about 40 Gbps (Gigabits per second).

What is OC level?

What is Optical Carrier (OC-x) Levels? OC-x stands for Optical Carrier Levels, is a set of signaling rates designed for transmission over Synchronous Optical Network (SONET) networks. The term “optical carrier” indicates that SONET runs over fiber-optic cabling.

How fast can an OC 3 line deliver data?

OC-3 runs at a speed of 155 Mbps (megabits per second) where a T3 line runs at 45 Mbps which is a significant difference in the speed of data transfer.

What is an OC 48 circuit?

An OC48 is a large T1 configuration that is a high-speed digital connection for voice and Internet. The OC48 is for very large applications where large bandwidth is needed. It is used as a major networking backbone for large companies and universities. OC stands for optical carrier.

What’s faster than a T1 line?

A T1 line plugs into your network’s router and has 24 channels. Each channel is capable of a maximum speed of 64Kbs. That means you can expect T1 to carry data at 1.5 Mbps (upload and download). A T3 line is faster, at about 43 megabits per second.

What is better than a T3 line?

T1 Line. A T1 line is comprised of a series of digital channels that allow transmission for voice and data at a speed that is much faster than a standard Internet connection. This type of connection is cheaper to install than a T3 line and the transmission of data and voice is not as fast as the T3 line.

How fast can an OC-3 line deliver data?

What is the line rate of OC 48 and OC 192?

What does OC-3 stand for in SONET network?

Depending on the system OC-3 is also known as STS-3 (electrical level) and STM-1 (SDH). OC-3c (“c” stands for “concatenated”) concatenates three STS-1 (OC-1) frames into a single OC-3 look alike stream. OC-12 is a network line with transmission speeds of up to 622.08 Mbit/s, often used by ISPs as Wide area network (WAN) connections.

How does a Concatenated STS ( OC ) frame work?

The three STS-1 (OC-1) streams interleave with each other so that the first column is from the first stream, the second column is from the second stream, and the third is from the third stream. Concatenated STS (OC) frames carry only one column of path overhead because they cannot be divided into finer granularity signals.

What does OC-3c stand for in optical transmission?

OC-3c (“c” stands for “concatenated”) concatenates three STS-1 (OC-1) frames into a single OC-3 look alike stream. The three STS-1 (OC-1) streams interleave with each other so that the first column is from the first stream, the second column is from the second stream, and the third is from the third stream.
