Fiber optic cabling FAQ

1. Choose multimode or single-mode? Both have any different?

Generally speaking, the user requirements of the optical fiber transmission distance is short, such as hundreds of meters, with multimode fiber can, but if the transmission distance for thousands of meters and beyond, the signal of the relay in conditions must use single-mode optical fiber.

2.4 core, 6 core, 8 core core or more?

Optical fiber transmission task to be completed, a charge must be at least one article two core. In fact, there are 4, 6, 8 and even more of the optical fiber core, excess core can be used to make a backup, can also do more transmission channel.

3. Is the box or frame hanging optical fiber optical fiber distribution frames?

Hanging optical fiber box usually in a small optical fiber network, such as in a 4 core optical fiber, but if the optical fiber quantity is more, frame type distribution frames will show its advantages, it can and switches router in the same cabinet inside, convenient centralized management and more safety.

4. FC, SC, ST, LC, MTRJ is what interface, this using a what kind?

These different interface in a different environment are useful to, no unified standard, their difference mainly reflects in connection method and appearance, is as tight as screw directly card or? Is a square or round? Is the big or small mouth (big more take place, small mouth may have more port density)? Are two separate or synthetic one head? Users need not too concerned about specific interface, noted that if the already existing old optical fiber system extension, it must be to match each other to do so.
