However, the sector soon came under scrutiny, especially from the U. S. government, which provided most of the schools' funds; it was estimated that some 85 percent of Phoenix's revenue was from federal student loan programs. Critics noted that students attending for-profit schools—who were often poor or veterans—typically carried more debt than those in nonprofit institutions, and they had the highest rate of student loan defaults. In addition, those attending for-profit schools had higher drop-out rates; in 2008 only 9 percent of first-time full-time students seeking a bachelor's degree at Phoenix graduated in six years.

In 2015 the Federal Trade Commission began investigating the school for deceptive business and marketing practices.
The debt that's crippling your company isn't on your balance sheet. Here's what to do about it. D ebt has been around for thousands of years. You borrow money. The lender charges interest until you pay the money back. It's simple. More recently, the software development community coined a term for another kind of debt: technical debt. Technical debt is the notion that taking shortcuts while writing code (or making repeated changes to code) has consequences later. "Shipping first-time code is like going into debt. A little debt speeds development so long as it is paid back promptly with a rewrite … The danger occurs when the debt is not repaid. Every minute spent on not-quite-right code counts as interest on that debt. Entire engineering organizations can be brought to a stand-still under the debt load of an unconsolidated implementation…" ––Ward Cunningham Financial and technical debt are now largely well-known concepts, and they play an enormously importantly role in organizations. But a third kind of debt exists — potentially more pernicious than either of its cousins — and anyone hoping to build a sustaining organization in the 21st century needs to understand it.
Different SFP types even if they are Single Mode, support different distances. • 1000Base-TX (up to 100m) • 1000Base-LX (up to 10km) • 1000Base-SX (up to 550m) • 1000Base-ZX (up to 70km) 10 Gigabit Ethernet (1000Base-T) is know as 802. 3ae in network cabling and it is used only with Optical cables. With Multi Mode, it is up to 300 meters. But with Single Mode SFPs, this distane can be up to 80 km. Fiber Optic cables are high capacity cables. Beside lower speeds, they are also the cables that is used for 100Gbps connections. To learn Networking Connectors, you can also visit Networking Connectors Lesson. Fiber Optic Cable Types In network cabling Fiber Optic cables has different modes. Generally we can divide this into two: • Multi Mode Fiber • Single Mode Fiber Different SFPs can be used with these Modes also. And this different SFPs provide different properties and distances. You will also hear too much LX, SX, ZX etc. These are the terms used with Fiber Optic Cables and each of them has different capability.
