Shulou(Shulou.com)06/01 Report--

The first question: the difference between fiber optic cables?

1. Appearance

2. Transmission distance

3. Wavelength

4. Core diameter

The second question: how to interconnect the two switches through optical cable?

1. Optical cable (define the type and length of optical cable)

1. Switch

2. Optical module (define the type and speed of optical module)

3. Optical fiber jumper (define the type, length and speed of the jumper)

5. Couplers (define the type of couplers)

6. Tail fiber (specify the type, length and speed of the jumper)

7. Optical fiber distribution frame or optical fiber terminal box (clear specific type)

The third question: there is no communication between the two switches?

1. Live status of the switch-> switch interface failure-> replacement method

2. Interface status-- > down

3. Check module-- > replace new module or existing normal use->

4. Check the jumper-- > replacement method

5. Replace the unused optical fiber interface on the optical fiber distribution frame-> replacement method.

6. Check the transceiver power of the switch-> 1, check whether the switch interface supports viewing-> 2, test with optical power meter (test range, light first and then test light)

)->

7. Coupler wiring is not firmly plugged-- > there is a problem with optical cable fusion.

8. Optoelectronic multiplex port-- > open optical port

9. Negotiation rate of optical interface

Note: check the interface optical power (the optical module needs to be identified by the network device)
