It’s time for a few more pics from the the world of unacceptable fiber optic splicing. The following photos shows a splice tray from an OPGW 24 fiber splice location mounted inside a Windsor splice closure. The first pictures shows that the tech used connector boots and silicon to protect the fibers from the edge of the steel tube. It didn’t work. This next one shows why there was high loss fibers in the tray. Poorly routed fibers caused macro bends and resulted in a few broken fibers as well. The customer was turning up a 10 gig connection and had high loss fibers across 3 splice locations. All locations had to be...

Time for a few more pics depicting unacceptable fiber optic practices. This first one is a classic. I’ve been in the business a long time and I can say that this is the first time I’ve ever seen this. The tech defiantly had no clue how to prep and wrap the cable entrys on a Coyote closure. These next two come as a surprise. (Not really) “That one you go to next should be pretty easy. It’s only a Tyco A with six splices in it. One of our in-house tech’s did it about a year ago.” If your fiber tech’s are doing this kind of work you might consider re-training...

Working with fiber cable as a technicians the first rule of thumb is to be aware. You always have to be on your best game constantly evaluating the task at hand. Sometimes the obvious solution is not always the best solution. At times engineering firms may route a fiber cable through what I call a field “anomaly”. In this case the anomaly was a water hazard. The cable pedestal was place smack-dab in the middle of a permanent ground spring. When not to touch a fiber cable Geographic Location: Above the 39th parallel Work to be preform: Open cable and install grounds Situation: Water around pedestal rises above the ring cut’s height from the ground 10 months out of the year. A little background – on many US FTTH projects there are no splice cases installed but rather a pedestal is set and the cable is prepped directly into the mounting hardware of the unit. In most cases the cable’s ring cuts are just above ground level. Say 6 inches. It is also common practice to open the fiber cable jacket and ground both cables even though there is no splicing to take place at the location. This serves 2 purpose’s, grounding the sheath and access to locate wire for locating the buried fiber optic cables (BFO). Solution: Do nothing but stencil the pedestal. Conclusion: Opening the fiber cable at this location accomplishes one thing real well. It allows a path for water to enter the cable! Water entering any fiber cables lifetime is bad but water getting into a cable where the chance of it freezing solid is...
