How to connect ofc cable to switch?
I have a basic knowledge of network and need some help.
I need to connect 4 Floor Building with 4 Cisco 2960 - 48 ports switch each other and it needs to be through a fiber. So all PCs connected to each switch would reach the LAN/WAN from the other switch. (attached is the image here with)
I see that the 2960 has 2 SFP ports each port of each switch should connect each other or how?
My simple question is:
1. What cable / patch code I have to use = Single-mode or Multimode? ( distance for each switch will not more then 25 mts)
2. Do I have to use SFP or SFP+ module?
3. What kind of SFP/SFP+ module I have to use = Single-mode or Multimode?
4. What kind of connector should patch code have = LC / SC or ?
5. How to connect each switch with redundancy like ...each switch should be interconnected with each other or I have to choose Cisco
3750G which has more then 2 SFP ports (option#1 & opetion#2 = attached here with) = Kindly advice..
Kindly advice the best practise for connecting cisco switches over fiber.
Any help is appreciated!
- Firstly, Insert the SFP module into PoE switch's SFP slot.
- Next Take off dust protection cap on the SFP module and connects fiber cable to the SFP.
- On the other side, repeat the above two steps to complete the fiber cable connection with second PoE Swith.
Media converters today are widely deployed in all sorts of industries and sectors to provide a connection between copper and fiber, including security surveillance, government defense, enterprise, campus LANs. The classic small footprint makes media converter a perfect fit to install for desktops, wire closets, and data centers. Although the application environment of media converter may vary, the cabling method is rather identical in essence. The following part illustrates two frequently-used cases of how to connect media converter.
As it is more of a commonplace to deploy a pair of fiber media converters in a network, a single media converter is sometimes needed to link copper cabling to a fiber device. In the figure below, a fiber media converter with 1×SFP slot and 1×RJ45 is applied, connecting the Ethernet switch (Switch B) of all RJ45 interfaces to an SFP switch (Switch A). The steps of connecting fiber optic cable and copper cable to media converter are as follows:
1. Connect the copper port of Switch B to the RJ45 port of fiber media converter using a UTP cable (Cat5 and above).
2. Plug an SFP transceiver into SFP slot on the media converter, and plug another SFP module into Switch A.
3. Insert a fiber patch cable into the SFP transceivers on the media converter and Switch A.
A pair of fiber media converters are often applied to link together two copper cabling systems for extending transmission distance. It is also the most common scenario using media converter in a network. The following steps show how to use a pair of media converters with network switches, transceivers, fiber and copper cables.
1. Connect the copper port of Switch A and RJ45 port of fiber media converter #1 using a UTP cable (Cat5 and above).
2. Plug an SFP module into SFP slot of fiber media converter #1, and plug another SFP module into SFP slot of fiber media converter #2.
3. Use a fiber patch cable to connect the fiber media converter #1 and fiber media converter #2.
4. Connect the RJ45 port of fiber media converter #2 to Switch B using a UTP cable.
Note: Optical transceivers are basically hot-pluggable devices, so there is no need to power off the media converter when inserting transceivers into the corresponding ports. Always remember to remove the fiber patch cable before removing the transceiver, and install the transceiver on the media converter before inserting the cable into the transceiver endface.
Media converters are simply plug and play devices, yet you still have to consider some factors when connecting them to the network. It is better to choose a flat, secure place to install the media converter. Leave ample space around the converter for ventilation.
Media Converters are designed for easy use in optical fiber transmission. When the connection does not work as expected after setting it up in a network, we need to do some troubleshooting. The checking include but not limited to the following six aspects:
1. The POWER LED on the media converter is off and the unit is not receiving power.
2. The SYS LED on the media converter is off.
3. The SYS LED on the media converter is blinking slowly.
4. Network performance between the twisted-pair port on the media converter and an end node is slow.
5. There is no communication with the devices connected to the media converter.
6. When the media converter is applied for the network, the whole link of the network can not communicate constantly.
