Issue
Customer requires to calculate approximate bandwidth of the system in 3 differing networks. The reason given was that they require to determine this in order to differentiate whether single or multi-mode fibre is required ?
Product Line
TCSESM083F2CU0 - 2 100 FX-MM refers to 2 ports @ 100Meg MM and
TCSESM083F2CS0 - 2 100 FX-SM refers to 2 ports @ 100Meg SM.
Resolution
To answer to your customers overall question, the decision to implement Single mode Fiber over Multimode Fiber is not related to Bandwidth, but rather to the distance that the proposed fiber runs will be deployed over.
The Bandwidth, if for example, you're using the TCSESM switches, remains the same (100M for both Single or Multimode).
There are different switch types (model numbers) for the different media types (SM, MM), note that the bandwidth for each is the same. If its a 100M fiber link, it has a maximum bandwidth of 100M whether using SM or MM fiber. (The overall bandwidth is 200M as the link is full duplex).
(MM being Multi mode and SM being Single mode, NOTE that both switches are the same 100Meg). This information can be found on the chart on page 11 of the TCSESM User guide. On page 39 you will see a chart detailing the distances MM and SM.
In most cases, installations within a building or adjacent building, Multimode is adequate. For those applications where the system is expected to span large distances, Singlemode will need to be used. (Note: Singlemode systems require considerably higher budgets to deploy, both the switches and the cable itself are significantly more expensive than Multimode systems - with no bandwidth advantage).
