A track record of success
A Citynet OC Fiber Optic Network.
The ideal solution for high end bandwidth users when connectivity is essential for operations.
What is an OCx Circuit?
'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. Certain multiples of the base rate are provided below with bandwidth amounts. Asynchronous transfer mode (ATM) makes use of some of the Optical Carrier levels.
Optical Carrier lines provides larger organizations with dedicated Internet connectivity. These Optical Carrier Level circuits are an ideal solution for high-end bandwidth users where connectivity is essential for operations.
An OC3 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). The speed of an OC3 connection is 155Mbps; equivalent to three T3 lines or 100 T1 lines.
An OC12 is approximately equal to 4 OC3s and runs at 622 Mbps. which makes it an excellent point-to-point IP delivery connection. The advantage of an OC-12 is that bandwidth can be added without any major system overhauls. An OC12 can also allow a business to have unlimited IP addresses which insures unlimited growth.
An OC48 works as a reliable fiber optic backbone for large networks which require volume extensive voice/data/video traffic. It is a long-haul backbone fiber connection capable of transmitting data at 2.45 Gbps.
