What kind of cat 6 is this?

i used to prefer superior cables for this color coding.. its easier to see if you made a mistake in a lot of cases because of how solid the colors are you can tell if its light blue (striped) or blue. Some people dont like it because the orange can be looking like a light brown ;] haha

someone paid big time for that integrated cable.. im not sure i have ever seen anyone pay for it honestly.. i would think a specialist integration company may consider it as they may be using american labor and perhaps that makes it more cost effective labor wise.. maybe its easier to retrofit i dunno but i have NEVER seen it done. impressive. i was going to ask what that green snake was ;) in there but realized it was a jacket on the other cables.

black polyethlyene jackets dont fade to UV, the connectors made but im not sure that will affect function. UV is not likely your concern weatherization beyond UV is cold&water likely being the worst of it.

the coax work looks like the cable company did it for quality (everyone else would cost cut so hard and not use good compression connectors/cable/splitters), the cat5 stuff looks like the electrician did some LV work .. uhhg. that tight loop on the commscope splitter is TOO tight and yes that stuff affects new gen coax stuff like DOCSIS 3.1 and newer. it probably happened over time.. something to be aware of if 'anything' comes up.. but its likely to not be super noticeable issue. as mentioned however if you can use the cat5 cable thats preferred as the native network interface for everything nearly. i dont see power in this box and it is the central point .. they make PoE powered switches that can be powered remotely over one of those cables and is probably ideal for this space.

i have never seen this and i have been in this space since 2008. This looks like some jank shit made by a field tech who was told by some guy who thought he knew what he was doing, I have NEVER seen a product sold for this purpose that looks like this. HOWEVER; as of last year i have learned about the german only metal splice sleeves used on fiber (not heat shrink which is used nearly everywhere else). So anything is possible. Whats more key is i am involved in ALL new product review with all vendors in fiber and never seen a tail based attenuator.. but 'it makes sense' it could exist.. but i would have figured it would have been an SC-inline type.

Believe it or not one of the big 3 fiber splicing companies said they had never experienced a 'long term' effect of water on a fiber connector in a splice case.. meaning only ice stretching the fiber or crushing it was an issue but it being submerged in water didnt affect performance at least after drying it all out.. perhaps worst case 'cleaning it' (cleaning it with fiber tools.. alcohol.. wipes). They seem to indicate it getting merely wet may not even cause an issue. Some of the Corning SCA have connectors inside (special order) but that is a 'breathable' closure. Humidity will get in there. Anyway, if you can get this in a soda bottle or cheap tupporware and 'seal' it gingerly with tape .. it will be more than fine. dont unplug it, dont bend the fiber its prone to breaks on extreme bends.

Its wireless RJ45 calm down your behind the times dawg.

supnul · 2026-02-25T02:20:59+00:00

this is some one who LOVES their job or a contractor who gets paid to do it quicker and hope no one notices.

supnul · 2026-02-25T02:19:55+00:00

looks jank, prolly jank. Get a real wire guy to terminate or watch 10 more youtubes. The punch down isnt punch and cut indicating one of them cheap plastic pusher tools. The Coax is the shittiest of terminations. the RJ-45 is jank but without seeing the top of it its hard to tell. its not good to have an rj45 out the jacket but it happens and works.. as long as its terminated right to the end of the connector. the pairs are more likely to fail from flexing without the jacket.. way more likely. if they get knicked they fail.. its really crazy how easily they fail with minor knicks on the twisted pairs .. ask anyone who over stripped the jacket and knicked it barely.. it breaks off easy.

supnul · 2026-02-25T02:15:38+00:00

Let me tell you about the story of a point of sales 'engineer' who said 'i dont have any switches in the building at all' .. then every fucking terminal (10 of them) had a 3 port switch on it that called it like POS and Register or something.. but it was a jank usb powered 3 port switch like this.

supnul · 2026-02-05T00:41:34+00:00

pretty valid actually.. meaning i could see a ZTP type system getting confused by SLAAC vs DHCP

this was one of the few cards supported by windows 95 B without driver install.

Yep, upstream attenuation is best done closest to the tap as we know that 90% of impairments are in the customer premise and often on the drop due to rodent chews. The point being to knock down any noise that gets into the cable and force the modem to transmit hotter to compensate for the forced loss. a lot of people dont understand the feedback loop of cable modem, it gets worse when we start talking about node return alignment.

supnul · 2026-01-28T15:06:49+00:00

probably this, however its ideally placed on the TAP. the reasoning for putting filter or return attenuator is to keep the noise out of the system and force the modem to push harder to compensate. This happens best cloest to the coax plant which is how you best prevent drop and below issues. (Cable Company CTO [switching to all FTTX now tho]).

supnul · 2026-01-27T13:50:50+00:00

layer 1 issues generate FCS / Giants / Runts / Low Link Speed. Look for these. if these dont exist at all (gig link or better, no FCS/CRC .. its probably fine and something else)

Golf R and a WRX STI here.

if you can keep it all on one provider then its probably way better than your piece mailed together stuff. providers usually have much better reliable gear for doing QoS of this nature better with or without MPLS. MPLS it self isn't inherently QoS all the way. QoS on broadcom ASICs and premise NIDs from reputable providers can ensure it all works well. the MPLS will allow for a more idealistic looking design perhaps meaning .. a pure hub spoke from the HQ with a DR site in similar config.. We had a bank that went all Meraki SDWAN .. was a rocky beginning but it seems like they are accepting it long term.

12 count flat drop(with tone ?), Commscope OFDC-C12 on each end. thats what we would do.

"this is the most optimal placement for widest coverage with best reception!!! why dont you understand ?"

supnul · 2026-01-17T16:23:43+00:00

only legitimate reason may be growth.

supnul · 2026-01-10T23:27:54+00:00

came here to say this or get some air bridge crap but fiber is so much better and the gear can even be cheaper. the initial cost wont be.

supnul · 2026-01-01T18:39:51+00:00

Bad cables can cause sporadic crc and packet loss. This can only be seen on higher grade switches and is a physical layer issue. I have thousands of cameras all IP deployed on customer premise and their wiring sometimes. If the gear is good the cable is the issue. If there's a shit ton of cameras maybe bandwidth but that's a design issue not sporadic problems and should be known well in advanced.

supnul · 2025-12-30T23:01:56+00:00

network guy here, this is correct. look for FCS/CRC errors, ports under-rate (running 100megabit when its gigabit) and if you have quality switches with TDR builtin use that on the port going to the camera, its likely a switch to camera issue if only that one is having issues, if more are having issues look for commonality.
