Telegeography also has a gallery of telecommunications maps with a variety of formats and data sets. In April 2021, the PTC began construction of the 220-mile fiber optic project extending along the eastern part of the mainline PA Turnpike from the Harrisburg East Interchange to the Delaware River Bridge (I-76, I-276, & I-95) and the entire Northeast Extension (I-476) from Plymouth Meeting to Clarks Summit.

Greg’s Cable Map also makes the raw data and KML available for you to download. Hawk High-capacity Undersea Guernsey Optical-fibre (HUGO) i2i Cable Network.
The maps below are just images – click for interactive versions. Fiber Optic Gulf (FOG) FLAG Atlantic-1 (FA-1) FLAG Europe-Asia (FEA). TeleGeography’s global backbone map and Greg’s cable map are both very good attempts though. All the five MNOs (MTN, Tigo, Glo, Vodafone, and Airtel) licensed to provide telecom services in Ghana have deployed fiber optics cable either as a backbone redundancy to the already existing microwave transmission infrastructure and/or metro fiber network to provide the necessary data capacity and voice traffic to the end-user. Mapping the world’s backbones is difficult because there are so many cables, owned by many different telecommunications companies. The resources below show various parts of the Internet backbone graphically, letting you really see how information travels from your computer to web servers (and back) when you visit a web site.
This week in ITGS we did a Networks refresher, covering topics such as LANs, IP addresses, DNS, ISPs, and the Internet backbone (this is chapter 4 in the textbook). Splicing fiber-optic takes a well-trained technician to break open the cable and attach other fiber-optic to the backbone.
