Got an emergency call for help from another ISP.
Nearly zero info (no location, contact, access, pass/fail criteria, actual symptom) - just "Step 1: Please do an #OTDR shoot; Step 2: everything else follow"
... like do I need parts? where are either end of this cable? which strands are problematic? is it in service? can I disrupt? is there spare capacity/strands/parts? how long is the run? are there splices I should expect? can I ping something for success? credentials for equipment?
Arrrgh. Guess I'll pack the kitchen sink.
Pro-Tip: if you're going to beg for help, at least try to equip the person with some basics! Especially since it means I'm going to be driving for 3+ hours... (not that I had anything else to do...)
Of course, a big part of me suspects that if they could furnish me with some info, they probably wouldn't've gotten themselves into this mess in the first place. (Pro-Tip 2: #Netbox is free and fantastic.)
Bets on me ever getting paid/reasonably for this? Double-digit customers offline.

Почему мониторинг состояния оптики – это важно
По долгу службы в региональном операторе связи решил поделиться опытом, легкой аналитикой и мнением о значимости мониторинга оптики, т.к. концепция "работает - не трогай" в таком контексте не работает. Первые внедрения оптики на сетях РФ начались в конце 80-х годов. К 2025 году, по данным отраслевого издания , ТОП-5 магистральных операторов связи располагают более 1 млн. км оптических линий связи. Гарантийный срок службы оптоволокна, который задается производителем, равен 25 годам. Но что же происходит с оптикой за почти четверть нашей жизни?
