The state of Iowa announces “Dig Once” program
OFFICIAL NOTICE. December 30, 2021. The Office of the Chief Information Officer (“OCIO”) has released the first version of the State of Iowa’s Fiber Optic Network Conduit Installation (“Dig Once”) program. More information regarding this program can be found on the website at https://ocio.iowa.gov/dig-once.
The OCIO is leading and coordinating a program to provide for the installation of fiber optic network conduit where such conduit does not exist. To further the program, the OCIO has developed a website to help identify where opportunities may exist to lay or install fiber optic network conduit alongside state-funded construction projects involving trenching, boring, a bridge, a roadway, or opening of the ground, or alongside any state-owned infrastructure.
The Dig Once website provides access to information concerning the Iowa Department of Transportation (“DOT”) five-year state-funded infrastructure projects. The website provides a map of locations where anticipated projects will occur and a form to sign up to receive updates when new projects are identified within locations of interest. Please visit https://ocio.iowa.gov/dig-once to view this information. Questions may be submitted by e-mail to ociogrants@iowa.gov.

Frequently Asked Questions On OTDRS
Frequently Asked Questions On OTDRS And Hints On Their Use
OTDRs, also known by their technical name optical time domain reflectometers, are valuable fiber optic testers when used properly, but improper use can be misleading and, in our experience, lead to expensive mistakes for the contractor. We have been personally involved in several instances where misapplication of OTDR testing has cost the contractor as much as $100,000 in wasted time and materials. Needless to say, it’s extremely important to understand how to use these instruments correctly.
Video on how the Internet Works
I have a few nitpicky things and the video seems a little contrived, but it’s decent nonetheless. WISPs are not really mentioned, but others are not as well.
Fluke Networks explains fiber polarity
https://www.flukenetworks.com/blog/cabling-chronicles/b-c-s-fiber-polarity
Polarity defines direction of flow, such as the direction of a magnetic field or an electrical current. In fiber optics, it defines the direction that light signals travels through an optical fiber.
To properly send data via light signals, a fiber optic link’s transmit signal (Tx) at one end of the cable must match the corresponding receiver (Rx) at the other end.
