i am an administrator for a small fiber optical LAN network, it consist of 90 computer, some with 1Gb fiber and some 100 MB Fiber. Currently we have 6 AT8016 switches ( 16 ports 100 MB Fiber) and we want to replace this with 4 24 ports Fiber GB Switches,
Doze anyone have some recommendations of Cisco switches I can use,
Let me try to understand your requirement.
You need a switch with 24 ports of Fibre Optic with 10 Gb interface (fibre)?
If this is so, you can you a number of choices:
1. WS-C3560E-12SD has, as with previous post, 2 X2 10 Gb ports and 12 x 1Gb SFP ports.
2. 4928-10GE offers 28 ports of wire-speed fiber Gigabit Ethernet ports (SFP) and two wire-speed 10 Gigabit Ethernet (X2 optics).
3. WS-3560E-12D has 12 X2 10Gb ports. Using an X2 TwinGig Adapter converting 10 Gigabit Ethernet X2 Interface into Two Gigabit Ethernet SFP Interfaces.
Cisco Catalyst 4928 10 Gigabit Ethernet Switch
Cisco Catalyst 3560-E Series Switches
The next one up is to get a 4500 or 6500 chassis (including the Sup cards) and get the SFP/GBIC cards. Don't know if you want to go down this path because it's not financially sound.
Hope this helps.
