Quick question to check I am doing this correctly.<br />
<br />
I have a Fibre ST patch panel in office1 and office2. (100metres apart), no idea if multimode or single mode fibre.<br />
<br />
I have a Procurve 2830 switch in office1 and office2 with HP SFP Modules.<br />
<br />
I attach each switch to the fibre panel using and ST and LC multimode cable OM1.<br />
<br />
Anything else I need to consider?<br />
(1) fibre patch lead has red A and black B, are both of these used? / need to be plugged in the same way either side?<br />
(2) fibre sizes? om1 om2 om3 on the patch leads matter as it's only 100m? <br />
(3) I have no idea what fibre has been used to connect office1 to office2. The patch leads I have are multimode I believe. Can you mix?

Fibre ST and LC - connecting up 2 offices

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
