This unit is a patch tray for DWDM services. It contains 8 x LC Duplex adapters for system connection. At LHS and RHS front entry ports a very flexible guide link for entering/outgoing optical fibre cords is provided. This item guarantees the radius for all optical fibre cords, as they travel to the patch panel. Rear outlet ports are located at the LHS and RHS rear corners of the tray.
