What is an "OCx"?
'OC' stands for Optical Carrier and is used to specify the speed of fiber optic networks conforming to the SONET standard. SONET, (Synchronous Optical Networks), includes a set of signal rate multiples for transmitting digital signals on optical fiber. The base rate (OC-1) is 51.84 Mbps. OC-2 runs at twice the base rate, OC-3 at three times the base rate, etc. Certain multiples of the base rate are provided shown below with bandwidth amounts. Asynchronous transfer mode (ATM) makes use of some of the Optical Carrier levels.
 

 

What is an OC3?
An OC3 (Optical Carrier Level 3), can be three DS3s (T3s) or as one 155M pipe. The benefit in using DS3s is that each can be separated back out as individual T1s (each with 24 channels). To put it into perspective, the speed of an OC3 connection is 155Mbps. This is equivalent to 3 T3 lines or 100 T1 lines. An OC12 connection is 622Mbps, equivalent to 14 T3 lines or approx. 414 T1 lines.
 

What is an OC12?
An OC12 (Optical Carrier Level 12), is approximately equal to 4 OC3s and runs at 622 Mbps. which makes it an excellent point-to-point IP delivery connection. The greatest benefit to an OC-12 is that bandwidth can be added to a business as it grows without any major system overhauls. An OC12 can also allow a business to have unlimited IP addresses which insures that growth is never limited...
 

What is an OC48?
An OC48 (Optical Carrier Level 48), works as a reliable fiber optic backbone for large networks which require volume extensive voice/data/video traffic. It is a long-haul backbone fibre connection capable of transmitting data at 2.45 Gbps. To put it into perspective the speed of an OC48 is the equivalent of having 48 T3's OR 1,344 T1 lines
