The customer had problems with their Mircom TX3 card access system.
Solutions provided:
Overture Flower Mound contacted us about problems with their Mircom TX3 card access system, which was coming up intermittently or not at all. When we assessed the situation, we discovered the fiber was singlemode but the patch cords and SFPs were multimode. After replacing the multimode patch cords and SFPs with singlemode, the system worked as expected.
