I-2542-A25 RS-232/422/485 to Single-Mode SC Fibre Converter, 25 km
I-2542-A25 converts one RS-232/422/485 serial port to a single-mode SC fibre link of up to 25 km using WDM, with TX 1310 nm and RX 1550 nm over a single fibre.
- Single-mode SC fibre link up to 25 km (9/125 μm recommended)
- WDM single-strand operation: TX 1310 nm, RX 1550 nm
- One RS-232/422/485 serial port, 1200 ~ 115200 bps
- Automatic RS-485 direction control
- ESD protection on the RS-232/422/485 data line (IEC 61000-4-2)
- Designed to avoid lightning strike and EMI/RFI interference on the fibre path

Produktinformation "I-2542-A25 RS-232/422/485 to Single-Mode SC Fibre Converter, 25 km"
The I-2542-A25 is a single-strand fibre converter that extends an RS-232, RS-422 or RS-485 serial link over one single-mode fibre for up to 25 km. Wavelength Division Multiplexing lets two independent data channels share one fibre, with transmit at 1310 nm and receive at 1550 nm, so an existing single-mode line can carry bidirectional serial traffic without laying new cable.
Automatic RS-485 direction control removes the need to manage transmit enable signals in the host, and ESD protection on the serial data line helps the unit withstand electrostatic discharge at the connection point. The fibre path is designed to avoid problems from lightning strikes and EMI/RFI interference, which suits serial runs that cross noisy plant or long outdoor routes.
The unit mounts on a DIN rail and runs from a +10 VDC to +30 VDC supply, drawing 2 W. It supports baud rates from 1200 to 115200 bps and operates between -25 and +75 °C. The source notes that the I-2542-A25 and I-2542-B25 form a pair, so both ends of a WDM link must be matched accordingly.
Applications
- Extending serial RS-232, RS-422 or RS-485 links over long single-mode fibre routes
- Serial communication in electrically noisy environments where EMI/RFI and lightning are a concern
- Reusing existing single-mode fibre by doubling usable capacity with WDM
