Uplinking 2960-SI-series and Catalyst-2950

[freezone1]

I need to up-link two Cisco 2950 switches(24port) on Gigabit port(using optical fiber medium as the distance is more than 100 meters) with one 2960 switch(24 port). The 2950 switches are quite old and I dont understand what kind of termination connector will be used at each end or what type of converters will be used after LC Connector. I am attaching pictures of all the switches. Please suggest me how can I up-link both 2950 switches with the 2960 SI series switch using optical fiber.

2960 terminating end is called "LC" and the 2950 end is called "MTRJ".

If the requirement is to have the 2960 in the middle.

You need 2 1000base-sx MM SFP's 1 1000base-sx MM GBIC. 1 LC-MTRJ (MM) fiber patch cable and 1 SC-LC (MM) fiber patch cable.

Thanks Mathias,

You are right, the requirement is to keep 2960 in the center. So this is what I conculde;

2950G:(older)
1 Cisco WS-G5484 1000BASE-SX GBIC - And 1 SC Connector.

2950S:
1 LC-MTRJ (MM) fiber patch cable.

2960SI Series:
2 SFPs (GLC-SX-MM) are required on the 2960 side. Further and LC Connector will do the interfacing.

Please correct me if I am wrong.

Another thing I got to know is that MTRJ is 100Mb fiber so I guess I wont be able to get 1000Mb all the way.

Please advice.
