I have bought two WS-2948G switches from cisco for a lab. I now need to buy two additional modules for them WS-G5484. I've never worked with fiber so I was wondering if there are differences in fiber cables and what type of fiber cable I should use on these?
Generally when you're working with fiber you have to be concerned about two things:
1. Type of fiber:
- Long-Haul: Single-Mode, used for long distances.
- Example: Across a city
- Short-Haul: Multi-Mode, used for generally shorter distances.
- Example: Internal to your campus/building
*Caveat: There are different types of Single-Mode and Multi-Mode.
2. Connector type:
Both Long and Short haul fiber connects into your transceiver with a connector. Your WS-G5484 uses a SC connector type. More modern connectors use smaller LC type connectors.
Like Tom Says, since you have the fiber transceiver already (WS-G5484) this means you are going to need a Multi-Mode fiber patch cable with SC connectors.
In addition to the exact answer about MMF and SC-SC connectors, the PDF presentation linked here from Richard Steenbergen @ NANOG57 is the best introduction to fibre you'll ever find.
