have you tried beainies or wire nuts ?

The only way to really tell is to test it with the appropriate test equipment.

Personally, I would test them several times with varying lengths of cable before I would be assured of anything.


Sam

I just did this test.

Materials:

Approx. 100 meters of General Cable Cat5e CMR (gray), spooled
Two Suttle Apparatus Flexplate Cat5e jacks
Approx 2 meters of Commscope 0478 Cat5 CMR (blue)
8 Scotchlok UR splices
Two 6-foot stranded patch cords (cat5e)
Broadcom NetXtreme Gigabit NIC with cable diagnostics
Trendnet 5-port Gigabit Ethernet switch

Test method:

Installed Suttle jacks on each end of 100 meters of cat5e cable (spooled).

Connected patch cords to each end, one end to Broadcom NIC and one end to Trendnet switch.

Ran cable diagnostics, noted results. Verified proper network function (no packet loss/slowness).

Removed Suttle jack from one end of spooled cat5e cable and used UR splices to splice 2 meters of Commscope Cat5 cable to that end. Maintained twists up to UR splice as is consistent with good installation practice.

Connected other end of Commscope Cat5 cable to Suttle jack.

Reran network diagnostics. Noted results. Verified proper network function (no packetloss/slowness).

And...now....the moment we've all been waiting for:

Before splice:

Distance (M) ~99
Margin (dB) 17.569
Freq. Margin (MHz) 18.982

After splice:

Distance (M) ~102
Margin (dB) 17.443
Freq. Margin (MHz) 19.104


*

Distance: This field presents the estimated cable length in meters by averaging all four channels using Return Loss algorithms. The unit is in meter (m).
*

Margin: Margin yields the minimum distance between the measured cable pair and the maximum IEEE 802.3ab limits. The unit is in dB.
* Frequency Margin: This measures the minimum distance between the measured cable pair and the maximum IEEE 802.3ab limits in the frequency domain. The unit is in MHz.


So there you have. Running gigabit over a UR splice works just fine. So well, in fact, that this post comes to you through that splice. Oh, by the way, I did a flood ping to the Windows XP machine with the Broadcom card in it:

PING 192.168.1.197 (192.168.1.197): 56 data bytes
....
--- 192.168.1.197 ping statistics ---
135272 packets transmitted, 135268 packets received, 0% packet loss
round-trip min/avg/max = 0.1/0.2/1.5 ms

Looks good to me.

I don't have any beanies left. Wire nuts, well, they really aren't designed for small 24 gauge wires.

I wonder how well soldering would work.

I take it you're testing with the NIC, not an actual cable scanner?

This post is getting a bit silly. Heck, why even spice the cables? Just move the hub to where the shortest wires are?

Also, the post is almost two months old. I'm sure Mr. Bloom has taken care of the situation.

Yea, I guess it was a bit silly of me to suggest that scotchloks could be used. Everyone knows they only work for cat3.

I've done the RJ45 and jack a few times in a jam. It works fine, only for a last resort or a temp job. Never used UY or UR connectors for data though.

scothlocks are just fine, we used them on occasion on inside wire in a bind for the clecs dsl dry pairs we provided, we also used them on troubles for clecs dsl pairs at the ped when the numnut serv tech would tighten the bond clamp way way way too tight at the ped and crush conductors where you had no choice but to bop them together with spare bsw to make them reach the binding posts in the ped. and even after all their ridiculous testing standards they held us to the circuits passed everytime. use em quick, cheap and easy.

The day will come when there is no more like me...

Thank God
