8P8C RJ45 Cat6 Inline Coupler Type Keystone Jack, Black
Easy to use coupler style keystones allow you to use RJ45 terminated cables in the front and the back eliminating the need to splice wires while standing behind a rack. You can use pre-terminated fix length cables as well, eliminating the need for crimping. Fits all standard keystone wall plates and panels.
Questions and Answers
Such a seemingly simple part but truly a piece of junk product this time from MonoPrice.
Avoid these couplers at all cost.
Not worth the hassle to save a couple bucks.
PROS: Worked ok for a few months.
CONS: Started having all sorts of connection issues randomly on 2 of the 4 I have installed.
CONS: 2/3 of them worked great the other 1/3 have open conductors and shorted pairs.
ANY touch or manipulation of a ethernet cable plugged into one of these, on either side, can cause a temporary disconnect at best, to complete failure of the keystone at worst. This makes diagnosis very frustrating they can literally work fine while you are testing them in one position, then stop working when you plug the tested connection into the device you want to service. Then you start all over again and tear your hair out.
Due to my experience with this product I am never going to buy a keystone product from Monoprice again. Cables, certainly. Other products? YES! Keystones? NO. Not worth the loss of time over such a cheap part. Hopefully buying something twice or thrice as expensive from a competitor is the way to go.
PROS: Look nice when fitted into a face plate. The black colour lets me easily tell them apart from telephone jacks or cat 5 jacks.
Easy to break.
Avoid these like the plague.
The smallest amount of up/down pressure on the front panel cable connection WILL cause an unreliable connection in the keystone coupler. The reason for this appears to be the "open interior" construction of the coupler allows mated RJ45 connectors too much movement within the coupler to the point that it is very likely to have either no connection, a connection that is interrupted with the slightest bumb of the cable, or an intermittent connection.
I called monoprice to report the issue, was told I'd receive a call back, but never received a call. These couplers are nothing but problems stay clear!
The fit nicely into high-density panels.
They don't provide a reliable connection even for 100Mbit application.
My apologies for the issues you were having with our keystone coupler. I will definitely be passing this info onto our QC team for review and possible changes that may need to be made to the product. As for the call back you were supposed to receive sorry for that for we don't really offer tech support via phone for we are all online assisting customer through live chat. If we do get an opportunity to call we do call soon as possible and I was able to have one of our associates give you a call a few days I believe it was and he left a message for you. He will be following up with you the next chance he gets. Again my apologies for this.
It is possible that you may have received some defective keystones and if you like I can perhaps have some replacement sent out being tested before shipped as well. If you no longer have a need for them I can setup an RMA for a refund. Thank you again for your feedback and being a customer of Monoprice.
PROS: The jacks feel solid.
CONS: Unreliable connection, does not stay latched into patch panel (distributed by Monoprice.)
PROS: Easy to connect two Cat6 Cables
CONS: Like another Reviewer had stated, any up pressure on the connection and it is 100% Signal loss. I thought it was something else and was pulling my hair out. Then I realized it was the connector so I removed it from the equation and all my problems were solved. This is the first thing from monoprice that has ever not worked for me...it made my heart sad :(
PROS: Well, it worked until I decided to relocate the router. Then lost connection.
CONS: Isolated the connection issue to this coupler. When I took the wall plate off and tried to disconnect one of the cables, the thing broke apart in my hand with very little pressure. One of the internal leads broke off as well.
PROS: Worked as expected
PROS: Easy to use, snaps in place tightly.
CONS: No shielded options from Monoprice.
I just wish these came in different colors (blue, yellow, red, etc).
PROS: Plug and play. No tools required.
CONS: None at all.
