Hi All,

This is regarding Cisco2960(WS-C2960-24PC-S) model with C2960-LANLITEK9-M image. I would like to see if i will be able to terminate Fiber on this switch.
Please let me know the possibilities of terminating fiber on this model? Is this best practice and Will i face any performance issues if i do this way. I have attached a screenshot from Cisco site that It has two dual-purpose ports (10/100/1000 or SFP).

Kindly let me know more on this.


Thanks in advance

Hi,
you can either use Giga port in uplink or fiber uplink: this means that each couple of uplink ports may be use alternatively in fiber or copper.
Unless you buy an expensive gbic for the switch to use fiber on uplink to go faster than 1Gb, the only reason you should choose fiber instead of copper is the distance from the uplinked switch (copper has a limit of about 100 metres, while fiber can cover much longer distance).

hope this helps

Thanks Max but sorry about me being basic. but i didn't understand the line "each couple of uplink ports may be use alternatively in fiber or copper". I see only two ports(Gi0/1 and Gi0/2).

Does that mean those two uplinks can be used as one for copper uplink and the other for fiber uplink and if i need to do it for Fiber uplink do i have to take Gbic card ? Can you be little clear?

Hi,
you have 4 ports available: 2 are ready (the copper ones for Rj45 plugs), and the other 2 are empty (you'd need to buy and insert a gbic in it to make it function). If you insert gbics and put a fiber cable connecting to the uplinked switch, then the "parallel" RJ45 port is disabled.
This is true for both "couples" of ports

hi,
please see image attached: you have

port 1: you can either use bottom RJ45 cable or fiber cable if you have provided a gbic on the upper hole

port2: you can either use bottom RJ45 cable or fiber cable if you have provided a gbic on the upper hole

hope this is clear
cheers

Thanks Max. One more quick suggestion. As i don't have other end any switch to terminate Fiber, What options can i opt for ? Do i have to go for a new switch with Fiber ports or any Fiber transceivers would work for me ? Kindly suggest.

Hi,
you need to have a fiber port on the switch and a gbic to plug it in along with a fiber cable. For the gbic and cable you'd better contact a cisco sales representative to get the right part number.
