The BMXNRP020• are optic converters that work in a Quantum Ethernet I/O (EIO) . These modules enable to connect X80 and Quantum EIO drops to the main ring of the Quantum EIO on fiber optic cable without the need to use dual-ring switches (DRSs) for the copper-fiber conversion.
There are 2 models of fiber converters each supporting one type of fiber optic cable:
Quantum Ethernet I/O Networks
Using Ethernet as a backbone, the communicates with remote I/O drops and/or distributed I/O devices dispersed through the network via a Quantum CRP head module installed in the and modules (Quantum 140 CRA or Modicon X80 CRA) installed in I/O drops using copper cable. While DRSs enable the use of fiber cable, they also allow you to connect sub-rings to the main ring and to connect distributed I/O devices to the . DRSs need to be configured.
You can use BMXNRP020• fiber converters for the copper to fiber conversion and vice versa.
The BMXNRP020• fiber converters install on a local extended rack between the local rack Quantum CRP head module and next to each remote X80 CRA adapter module on the main ring.
On the local extended rack, the fiber converter works with the Quantum CRP head module. It allows:
On the remote I/O , the fiber converter works with the Quantum 140 CRA and Modicon X80 CRA adapter modules. It allows:
-
a fiber-to-fiber connection with daisy chain loop management.
-
a fiber-to-copper connection with daisy chain loop management, where the optical link connects to the fiber converter and the copper link connects to the CRA module.
The BMXNRP020• fiber converters allow an indication of communication disruption to be sent back through the network so that the system can recover within 50 ms.

In the example above, a fiber converter is installed in a local extended rack, allowing you to run copper cables from the Quantum 140 CRP head module to the fiber converter. From there, a fiber converter is installed in each X80 remote I/O drop so that all the X80 remote I/O drops are connected by fiber optic cable.
Fiber optic cable enables you to:
