I'm in charge of the new network installation in the new office of my company, and I have troubles wiring two network rooms (one for servers and incoming internet and the other one for wiring closets) via an internal optical fiber installation.
In both network rooms, I have a panel with Duplex Multimode optical fiber with SC connectors, linking the two rooms with 2 optical fibers. I chose to use Netgear Prosafe Gigabit switches to link the two network rooms, (https://www.netgear.com/business/products/switches/smart/GS752TP.aspx#tab-techspecs), 1000Base-SX Duplex fiber SFP modules to connect them with fiber (https://www.startech.com/Networking-IO/sfp/modules/1000base-sx-sfp-module~SFP1000SXST), and LC to SC optical fiber to wire them to my panels (https://www.amazon.com/Mcl-Samar-Jarreti-Optique-multimode/dp/B004Y0YTFY/ref=sr_1_1?keywords=FJOM3%2FSCLC-1M&qid=1560791159&s=gateway&sr=8-1).
So, both my switches have the SFP module, outputting Duplex LC connectors to Duplex SC on my panels via the optical fibers I bought.
My switches are working correctly, I can discuss from one another with RJ45 copper connections between them, and the SFP ports are ok, as I can stack my switches with SFP copper modules and cables and still send pings betweend one computer on each switch. It's really my design of the fiber connection that must be off.
Have I mistaken something about optical fiber installations? Is some of my hardware inadequate or incompatible? In the meantime, I'm contacting the company who wired the internal optical fiber, to make sure they are OK on their side.
Here is a simple diagram to visually check my installation. Note that there are other optical fiber SC connectors in both my panel because I have other wiring closets rooms, but with the same kind of installation (I am still trying to figure out how to make a single one work)
I'm a beginner in network engineering and still don't know if this is the right place to ask this kind of question but I'm in a bit of a dead-end and have little time left so I'm a bit desperate!
Thanks so much if you can help me :)
