Thank you for explaining the difference
Comment from : David Schnabel

Edit: b*/b Picked up Northern Cat 5e riser specification sheet indicates 0195"(495mm)OD, so 688 full Also, forgot to add to earlier comment I noticed your website with that 3/4” minimum and was definitely aiming for utilizing 3/4” but corner trim/edge bottlenecks to an 1" brief narrow allowance between the section of 2" wide void access between houses and the wide open exterior and made the 1/2" option the only solution as I'm avoiding making any holes with this method I can definitely see logic to requiring 3/4" minimum if traditional pulling method greater than 10' at a time are utilized I further researched and found 3/4” to be the requirement in publicly available PDFs for some universities in their telecom/data policies and procedures I couldn't find the rational but best guess it's a jacket integrity issue Is that 3/4” minimum primarily for protecting jacket integrity in a normal long pull technique? Off record could you see/guesstimate someone getting by with 1/2" if pulling a 10' stick by stick slowly but surely?brAny idea how Northern plenum(0175in OD) and Southwire(0185in OD) are within a reasonable 6 of each other, but for riser Northern(0195in OD) and Southwire (0244in OD) are a massive 21 apart?***brbrInstalling POE Swann cameras The Swann system included 60' 2 pair "Ethernet"(4 conductor-2 orange [on pins 1 and 2], 2 green [on 3 and 6]) and pins 4,5,7,8 are not utilized The lengths were inadequate and actually made test fitting deceptive because it's not real Ethernet and icing on the cake is no Cat/AWG/any identification on jacket(Swann claims Cat5e) they're blank; I've tested and the cables seem to work properly with the cameras but I've decided/been forced to use Cat5e plenum 47mm(0185in) OD specifically based on calculator showing ability to fit 7 in a single 1/2"(15875mm) EMT [using Engineering Toolbox-calculate how many smaller circles fit in a larger circle] and of course to achieve the necessary lengths Hopefully it fits in practice and not just on a calculator which indicates 8 smaller 4699mm circles at 70 full and best estimation of of 665 full with 7 runs in the same 1/2” EMT I would've preferred the lesser price of riser cable measuring 6198mm(0244in) OD but calculations appears to only allow for 4 runs at 60 full Prior to this I took Ethernet/data cable for granted, but now I see the POE camera market will stick cheap inadequate length cables to really make the consumer self installer to really think their install thoroughly and require way too much Internet searching I was also considering difficult to obtain 1000' Cat5e non-riser CM/CMG with OD 508mm and the calculator indicates 7 smaller 508mm circles at 717 full with 7 runs in the same 1/2” EMT The most outdoor exposure would in an alley without any direct rain between 2 "attached"[attached roofing material-otherwise 2" gap]houses but in the winter the alley can get down to 50⁰ F so that may be a point against as I understand it's for indoor use only; but as I understand it, "indoor" mostly refers to UV exposure and direct rain exposure which are not the case of this alley Any advice/ideas on CMP plenum vs CM/CMG non-riser? Would one be a better option for a 90⁰ LB conduit body[as opposed to a 90⁰ radius bend]?brbr *Of note the included Swann Ethernet cables were tightly wound in best described as 0⁰ folds and I've actually tested one that is mostly still tightly wound up and appears to be functioning properly Is Power over Ethernet more tolerant of severe folds in the runs?

Quiet down the cable?? Whats that??

Thanx! Got good info from it

True Cable Cat5e is tested up to 350 MHz, would it not theoretically provide better performance than a cheaper brand of Cat6 cable that was only tested to the 250 MHz minimum?? Seems like your Cat5e would have a little bit more headroom

Do physical differences between CAT5e and CAT6, apart from the one you just mentioned, also have to do with the twisted portion per inch that each twisted pair has, right? The more twisted the portion is, the better; related to minimizing crosstalk

Trying to install LAN in a few rooms on my housebrWas thinking on using the router provided by my internet provider to feed those ports on each roombrCan it be done?brShould I use cat 5e or 6?brWould I need to run the feed trough some sour of switch?
