Please log in for more thread options Some guy found a RJ45 splitter (2-RJ45 jacks to 1-RJ45 jack) over on ebay (search RJ45 spliiter) that look like the telco 1-line 2-line adapters, but yet this guy (and the ebay description) says these "splitters" .... Features: a.. Convert a single RJ45 outlet to two RJ45 sockets easily, point for more conveniently use b.. Increase the number of RJ45 network connections on an RJ45 outlet c.. Compact design, feel free to enjoy your internet surfing d.. Expand one RJ 45 outlet into two 8 wire RJ-45 T adapter, parallel wiring e.. Connector: 3 x RJ45 female f.. 100% Brand New. It doesn't even seem possible to have more "network connections" by just splicing more Ethernet wires together vs a dumb hub ???? I could see if you were trying to split out the tip/ring (4/5) or power (7/8) but an Ethernet splitter ????? -- ---------------------------------- "If everything seems to be going well, you have obviously overlooked something." - Steven Wright | ||||||||||||||||||||||||||||||||||||||||||||||||||||

Please log in for more thread options The advertiser did not say "Ethernet network connections", he said "network connections". Telephone systems are called "networks", also. However, his presumption that its compact size will somehow enhance your internet experience is both stupid AND leads one to believe he thinks you CAN tee an ethernet connection.

Please log in for more thread options I've had splitters like this in my tool box for the past decade, but
have not actually implemented them. Mine, are male on one side, and two female on the other. Imagine that you plugged one into a wall jack at the location of a workstation, and another in the closet where your switch resides. This would support two Ethernet or FastEthernet devices at the workstation location (e.g.: host, and network attached printer). Each device would utilize two of the four pairs within the 8-wire (e.g.: Cat 5e) cable. This is however, not an appropriate thing to do from a performance standpoint, and should not be standard practice. If you were utilizing GigEthernet, I believe all four pairs are used to support a single device, and therefore splitting would not be an option.

So, you would have to fabricate a custom cable for each of these connections at each end and then plug that cable into your cable-sharing RJ45 splitters.. 1/2 = 1/2 3/6 = 3/4 1/2 = 5/6 3/6 = 7/8 > This is however, not an appropriate thing to do from a performance

The splitters are used in pairs, one on each end of a single run of cable. <http://www.homestead.co.uk/productcategorydetail.aspx?CategoryID=51338&onspecialoffer=False>
