As shown in figure, our network topology is very simple, 40 m optical fiber to come in, pick up a enterprise routers, layer 3 switches, layer 3 switches 50 string mouth, with about 40, now existing in the question is: PC2 (PC1 of 35 ordinary PC, PC2 is 4 ordinary PC) room for distance too far, about 120 meters, I will pick up a small in one end of the nearest four switches, an Internet cable network cable diversion of article 4, 80 meters from PC2 four computers, a signal at the beginning, is now unable to connect to the computer, using network cable tester tests found that 1, 2, dim light (orange, white and orange), and the other is normal, excuse me what method to solve?
CodePudding user response:
120 meters, the distance, average five types of cables, theory is as far as 100 metres?CodePudding user response:
Visual so far still in good cables, if change nail in the wall of death, that consider the wireless relay? Without blocking too much, the feeling is two or three routers relay should be ok, but the network stability have sent some ah, after all, a router broke the line also collapsed, wireless users much like collapse when a router, but also good just four users,CodePudding user response:
1, check whether the plug is need to do;2, line change;
3, plus the repeater,
CodePudding user response:
Try using Ann PuLiu class lineCodePudding user response:
This question is too easy to solve, 100 m Ethernet cable, only to 1,2,3,6,1,2 is a pair of, now is the wrong with 1, 2, line 1, 2, change to another place on both sides (4, 5, or 7, 8), problem solved,CodePudding user response:
Need to add equipmentCodePudding user response:
Positive solution to the second floor, more than 100 m should add a relay, and of course, one possibility is that the poor quality cable, signal attenuation is serious, 80 m of attenuation is unusable,Proposal, first of all, measure the cable length, make sure no more than 100 m, and then change to a good network cable try,
CodePudding user response:
Another possibility is that 4 piece of your switches, the output signal intensity is not enough,CodePudding user response:
Er...How do you like me before this, the company...
Vast distances away from the office, warehouse...
Don't pull four respectively 80 meters of cable received PC2, find a PC2 several machines recently place would be better to put a small switch
Then, layer 3 switches from you out a line, separated by a repeater.
CodePudding user response:
Can try change four switches to a signal amplifier, my side has a similar situation, to warehouse field testing room is done not have more than 80 meters of cable signal, problem solved with a signal amplifier,Not only on the optical transceiver,
CodePudding user response:
In optical fiber, is not expensive,CodePudding user response:
In line, or 1, 2 and 4, 5 exchangeCodePudding user response:
Optical fiber positive solution, if indoor change a good twisted-pair cable can alsoCodePudding user response:
If the connection request is not high. You can try the 4 PCS set to 10 m.CodePudding user response:
Fundamental solution is to change the fiber, once and for all, maintenance is convenient, the construction of the cables in addition to a large project now few can really use the line, 80 meters or less can, once the critical or super long all sorts of problems, so don't move the original copper lines, increase the cost of a fiber and two photovoltaic modules is very low, also facilitate the solution of the problem,CodePudding user response:
The middle add a switch, choose a random location 40-80 meters,CodePudding user response:
Suggested two optical transceiver, from 100 meters skin fine, inexpensive and practical, better performance than twisted-pair, poor quality of twisted pair of 80 meters is no signalCodePudding user response:
is first checked if there is any damage, and then add a switch or a hub in the middle can solve,
