| We want to replace the Module interconnection between Lectern Module and FOH Module, currently build with SDI and Ethernet long runs, with a fiber connection. | We want to replace the Module interconnection between Lectern Module and FOH Module, currently build with SDI and Ethernet long runs, with a fiber connection. | ||

| Several situations in different Locations has showed, that long run copper connection, specially SDI are a problem in our use-case. This is mainly caused by the fact, that 20m is often not enough to make a proper connection between stage and FOH and all our existing longer SDI cables are more or less shitty. So instead of buying new long-run SDI cables with a length of about 50m we think it's a better idea to switch to fiber for a more reliable option. | Several situations in different Locations has showed, that long run copper connection, specially SDI are a problem in our use-case.

| We extend the Lectern- and FOH-Modules with a fixed build-in SDI fiber-converter with BD-LR module, and equip the switches in both modules with BD-LR modules in their SPF+ trunk ports too. On both sides these modules will be fixed wired to duplex E2000 D-Type ports at one of the patch-panels. For connection we add a cable-drum with ~100m quad fiber cable with E2000 connectors. | We extend the Lectern- and FOH-Modules with a fixed build-in SDI fiber-converter with BD-LR module, and equip the switches in both modules with BD-LR modules in their SPF+ trunk ports too.

| - | ==== LC vs E2000 ==== | + | #### LC vs E2000 |
| While LC is the by far more popular connector and substitutes are way more easy to find in case of a broken cable, E2000 is the more robust connector and since it has integrated dust-covers more easily to handle in an event environment with constant buildups and teardown. To keep us capable of acting in cases where just a LC cable is available the SDI fiber converters will be fixed in the case in a way, that the SFP modules LC connector stays easy accessible. | While LC is the by far more popular connector and substitutes are way more easy to find in case of a broken cable, E2000 is the more robust connector and since it has integrated dust-covers more easily to handle in an event environment with constant buildups and teardown.
