As we all know, SFP-OC48-LR2 is a type of Cisco SFP modules. But do you really know the meaning of the words in the SFP-OC48-LR2? I think the “SFP” and “LR2″ are known as SFP modules with 80km transfer distance by most people, while the “OC48″ is not understood by them including myself before today. And after searching on the internet, I write this article to talk about it.

In fact, many network engineers and IT managers are not up to speed on just what OC really means, although they have used the 2.5G SFP 80km or 1550 SFP 80km. And what all is available to enahnce their company’s applications within this bandwidth category. The first that we should know is, the OC is short for Optical Carrier (fiber optic based broadband network) with speed hierarchy starting with OC1 on optical facilities and going as follows.

OC1 = 51.840Mbps (the basic rate)

OC3 (3 times of OC1) = 155.52Mbps (about 155Mbps)

OC9 (9 times of OC1) = 466.56Mbps (not commonly used)

OC12 (12 times of OC1) = 622.08Mbps (about 622Mbps)

OC18 (18 times of OC1) = 933.12Mbps (not commonly used)

OC24 (24 times of OC1) = 1.244Gbps (not commonly used)

OC36 (36 times of OC1) = 1.866Gbps (not commonly used)

OC48 (48 times of OC-1s) = 2.488Gbps (about 2.5Gbps)

OC192 (192 times of OC1s) = 9.953Gbps (about 10Gbps)

OC48 is among the most used bandwidth that has applications including large enterprise or ISP backbone. Let’s discuss its specific advantages.

The utilisation of the internet by consumers and businesses is definitely an incredible market through which optical carriers are starting to supply the most leading edge appeal. With this particular facet of the internet world in your mind, any business or perhaps consumer should consider the incredible advantages offered in the OC48.

OC48 is used by larger businesses and corporations because they allow for an incredibly fast and dependable source of internet. They are currently equipped to handle probably the most amounts of data in the industry as well as offer the fastest speeds. As such, businesses that current operate on a much grander scale and would like to keep growing are the ones that help the most from this technique.

Within the optical carrier realm of data connection, there are quite a few ranges of speed and capability which are numerically labeled. The OC48 is really the mid-range source of data which allows to have an incredible fast rate of internet connection overall. It is probably the most popular carriers to replace T-Carrier lines. The T carriers of web connection for businesses was discovered and implemented in the 1960s for people who needed the fastest and more reliable data sources on the market for that time. This form of internet sourcing actually led the way for intranets and broad area networks that kept businesses connected all the time.

OC48 is really within the mid range of connection and strength. This range is complete with a processing capacity for 2.5Gbps which is actually quite robust. This really is perfect in strength for just about any larger business to expand within too. This optical carrier system could be quite expensive to establish for just about any business that often ranges in beginning costs of 30 to 40 thousand dollars. The monthly rates are quite steep as well yet many companies feel the costs are justified. As such, this is often from range for smaller to medium-sized businesses.

In order to operate an OC48 connection, there must be an amazing strong telecommunications source operating it. Some of the more reputable isps are beginning to come on line with this particular strength of the system. This, in turn, makes it more readily available for those that wish to use it.
