A few notes:

If you've known me and/or been mutuals long enough you will recognize that I often re-use songs in my shipping playlists. This is because I have a tragic old man yaoi ship type and that type happens to perfectly embody shit like "You Make Me Feel Like a Whore." If you're new and have never witnessed this phenomenon, welcome.

I have old millenial music taste so there are a lot of old millenial songs.

I exercised what I consider godlike willpower and only included 2 K-Pop songs. However, they are THEE gut-punchingly appropriate songs to include, imho.

Similarly, Kuusou Rumba was a weird one that kept making the cut as I curated this playlist, but hey. Hey go read those lyrics. I implore you. Pipiscore.

This Day in History: A long-stranded B-17 crew, rescued (pt 3)

On this day in 1943, the last surviving members of a B-17 crew prepare to leave the Greenland Ice Cap. They’d been stranded on an icy glacier for months.

The entire crew had survived the crash on November 9, but early rescue efforts had been a mixed bag of successes and failures. (See yesterday’s post.) By December, seven men were still trapped on the glacier: Six of the original B-17 survivors, plus one man, Don Tetley, who’d been attempting a motorsled rescue when his partner was killed.

The situation was grim. The worst of winter was coming, and further rescue attempts would be difficult. The stranded men would have to save themselves. Tetley and three others would take the one remaining motorsled to Ice Cap Station, about 30 miles away. They’d send a new motorsled back for the others.

Tetley’s group departed, carefully treading across a field of ice crevasses that surrounded the B-17 wreckage. Just when they thought they’d cleared the field, one man stepped on a hidden crevasse. The move was fatal.

In a sad twist, Private Clarence Wedel was a newlywed. His wife would soon give birth to a little girl who would never know her Daddy.

Tetley’s group tried to continue, but its motorsled broke down. They’d traveled only 6 miles from the B-17 wreckage. Fortunately, a resupply plane flying overhead happened to see the new “Motorsled Camp” that Tetley’s men created. They would start getting supply drops, just like the men at the B-17 wreck.

Fiber optics has now become the backbone of our communication network. These are slightly larger than a human hair and relay billions of data across the globe. As many companies rely on fiber optics and fusion splicer capability so it becomes necessary to do proper maintenance to prevent any disruption issues.

These fiber optics are quite powerful but they are also extremely fragile and can be damaged with bending as well as contamination brought about by the accumulation of dirt. Contamination by dirt can be a small thing but it can cause unreliability of the network and wide performance problems.

Maintenance of Fiber Optics

To optimize the performance of your fiber optics regular maintenance is the key. Specifically created tools for cleaning is essential but getting to know which one works best would ensure that you are not left with future issues.

Wipes should be used once as fiber cleaner it can cause recontamination of the cleaned surface. The liquid material that is required to use with the wipes should be made of high-quality water-free isopropyl alcohol. One should look for reagent-grade alcohol as it does not freeze unlike others, this type of liquid is very safe for humans and cleans static very well.

Few companies sell dry cleaning materials that one can use to remove dirt on the cables. Technicians should first try to do a dry cleaning technique before implementing wet cleaning that involves tools such as a pocket cleaner or a cartridge cleaner. The film would remove any dirt from the cable, lint-free wipes or swabs may also be used. You can buy fiber interferometer online.

Best Practice When Cleaning Cables

Before doing any cleaning of cables, one must turn off any laser sources by unplugging the cables at both ends. If necessary, safety tools such as clothing material, glasses, and boots should be worn to protect oneself as well as prevent any damage to the cable.

Before cleaning, the initial inspection would allow one to use the proper cleaning tools thus saving time and money. They must be stored in a clean, dry and resalable container to prevent any contamination of the cleaning tools.

Between four hundred and one hundred degrees of magnification can be achieved by Fiber optic microscopes and on the needs of the user, the level of magnification will depend.

Because of their specialized nature, Fiber optic microscopes are not available from the same sources, which provide digital or regular microscopes, and by companies, fiber endface microscope is usually bought instead of individuals.

Fiber Optic Microscopes Types

In several varieties, Fiber optic microscopes come; similar to those on compound microscopes, the simplest of them have eyepieces through which their users look at. Its own video screen is there in a more sophisticated model of fiber optic microscope; for those who on a regular basis use a fiber optic microscope, this is the preferred technology.

To provide images of the end faces of fiber optic connector ferrules, a fiber endface probe is used so that with their transmission performance, any problems can be seen. Its operator can detect any scratches, debris, or dirt with the microscope, which with the transmission, may be interfering. Operating for up to forty hours on three or four AAA batteries, most fiber optic microscopes are handheld units.

Fiber Optic Microscopes Traits

To secure the fiber optic cables, You should look for models including connectors, if you're thinking about buying a fiber optic microscope; otherwise, to hold the microscope still with one hand and hold the cable steady with the other, you'll find yourself having to struggle.

As compared to those without cable holders, the microscopes with them will cost more than but as compared to make up for the difference in cost, the time you'll save inspecting the cables will more. You can also buy fused biconical taper machine online.

There are both electronic and optical fiber optic microscopes; and to spare you from having to look at it through an eyepiece, the image of the cables will be displayed by some of the more expensive models on a monitor.

From Prior Scientific One, fiber optic microscope is actually software controlled. The software is programmed to search for fail or pass the cable based on them and certain characteristics in the microscopic image.

Most fiber network outages aren't caused by equipment failure. They're caused by problems that were already there — undetected. 🔍 

Splice loss creeping up over months. Return loss degrading in a section nobody tested after installation. A connector end-face that failed visual inspection and was passed anyway. 

Fiber Optical Test gives telecoms, data center operators, and enterprise network teams the tools to find what's already there before it becomes a crisis — OTDR systems, optical spectrum analyzers, AI-based fiber monitoring, bit error rate testers, and end-to-end fiber certification platforms.

Fiber optic cables power modern communication networks, but even minor issues in cables can lead to major connectivity problems. Fiber optic testing helps detect signal loss, faults, and performance issues before they disrupt services.
