OC-192 broadband basics include the fact that Optical Carrier (OC) levels are a range of signals carried on a Synchronous Optical NETworking (SONET) network. The number 192 indicates that this speed is 192 times faster than the data rate of the bit stream carried by the signal.
Optical Carrier 192 is also known as Synchronous Transport Module 64 (STM-64) or 10G SONET. SONET Synchronous Digital Hierarchy (SDH) is currently the standard for optical telecommunications and OC-192 lines are currently the fastest connections that are commonly available. In order to learn more about OC-192 service you will need to know the following:
- The OC-1 rate is 51.84 million bits per second (Mbps) so the rate of an OC192 connection is 9953.28 Mbps with 9621.504 Mbps being payload.
- The common version of 10 gigabit Ethernet (10GbE) is called LAN-PHY and is not compatible with OC-192 equipment although a variation of 10GbE called WAN-PHY is designed to work on OC-192 equipment. Both variants can be used on a Wide Area Network, so the names can be misleading.
- The most common use of OC-192 connections is for backbones of large Internet Service Providers (ISPs).
Learn more about OC192 connectionsThe technology comprising telecommunications can be extremely complex and uses many terms that may be unfamiliar to business professionals. There are many white pages available, in addition to articles that provide valuable information about OC-192 connections.
Measure the actual speed of OC-192 connectionsThe rated speed of an Internet connection is the theoretical maximum speed the connection can achieve. There are many reasons for an OC-192 connection to have a throughput less than 9953.28 Mbps including latency, loss of signal and bit stream errors.
University of Michigan provides a Java-based tool that can test the actual speed of an OC-192 connection. Learn more about OC-connections and access valuable resources, including a speed test, at Bandwidth.com.
Select OC-192 providersThese carriers should be able to offer stable and reliable connections for businesses that are competitively priced. OC-192 service providers may also offer a range of actual throughput speeds that users can expect to achieve.
- Users can obtain their choice of OC-192 equipment independently of the OC192 service provider. SONET allows interconnection between network providers regardless of the brand of equipment, so the provider can purchase equipment from one vendor and interface with equipment from another vendor.
