I know that kind of concrete row pipe, glass steel pipe. I would like to know when the cable buried, crossing the SC pipe laying, such as wearing 2x2SC100 steel pipe laying, this section of the pipe is not considered row of pipe? Is there any pipe made of steel pipe? More
Regardless of whether the PCB is complex or not complicated, the correct operation or the removal of wiring, and then re-edit the design rules, wiring layer set to the bottom of the effective, and then re-wiring, that is made into a single board. Your original top cloth has a wire, that you are two layers. To change the top of all the cloth to the bottom of the line, that you actually need a single board. To get a single board, the correct operation is what I said above. If you use the method to find similar objects to change the top of the wire to the bottom, there will be the top of the wire to the bottom of the change, and the bottom of the wire will have a lot of conflict, and then go to a re-wiring after re-wiring, not as good as all After the revocation. If the single-layer board wiring can not avoid the conflict, it had to place a cross-line.
Left and right in the fire in the ground, the socket L for the fire N is zero for the last one, but you'd better use the pen to test which is the line of fire
A fiber optic cable with a coupler and a fiber jumper. One or more fiber optic cable with a fiber patch panel (patch panel has 4 to . one can even a core) according to your situation with a 6 fiber optic cable computer room: fiber patch panel 8 (a specific number of your own according to the actual calculation) coupler 8 fiber jumpers 8 (4 pairs, the packaging is a pack of two) (fiber jump Line can be based on the actual needs of the buy, 6-core fiber may only use two cores, the other backup) ------ weak: fiber patch panel 8 a coupler 8 fiber jumper 8 ( 4 pairs of packaging are two a pack) (fiber jumpers can be purchased according to actual needs, 6-core fiber may only use two cores, the other backup)
