RSMUX2 Optical multiplexer with 2x optical interface and 2/4x RS232/422/485

The RSMUX3 from Bitstream is an optical multiplexer of 2x RS232/422/485 streams into fibre. Multiplexer allows connection of RS232/422/485 serial interfaces over fibre links with the maximum distance of 100km and provides complete isolation between devices and resistance to disturbance occurring along transmission path. Depending on the specific versions, device can be connected using multimode or single-mode fibre. WDM and SFP versions also available. In basic version device is equipped with one fibre optic interface, version with two optical interfaces is also available.

RSMUX3 provides fully transparent operation. Each serial interface is sampled with a frequency of 20Mhz, which allows on data throughput of the RS to 230.4 Kbps (RS-232) and 2Mbps (RS-485/RS-422) with +/-60ns pulse time distortion. RS485 ports can be set up for 2-wire or 4- wire. Depending on the version of the device, multiplexer can work in point to point (with optical path protection), bus and ring topologies. Serial interfaces can be configured through DIP switches. In addition, each port has two independent LEDs activity data in the transmitter and receiver, which greatly simplifies the process of installation, commissioning and maintenance.

The device is available in versions with one or two optical interfaces. In the case of devices with two optical ports can create connections with protection for the fiber optic link. However, when building a ring on the basis of one optical port (it cannot be a version of the WDM) we have no redundancy. Fiber ports can be implemented by the built-in optical interfaces (single or dual fiber) or by SFP. In the case of the creation of the ring it is possible to simultaneously connect up to 64 devices.

The RSMUX3 comes in multiple variants, to quote an exact model please provide a part number using the designations in the attached data sheet:
