Fiber Optic Modem GT-RS232, Retail and Wholesale Fiber Modem

Product Description:
The SFT/R-D-13 apply to Rs232/Rs485/Rs422 over fiber optic field. In virtue of this productor, Rs232/Rs485/Rs422 could be extended to 2 km (multi-mode fiber) or up to 20 -80 km (single- mode fiber). RS-232 and RS-422/485 interfaces can be used at the same time, Maximum three channel and each channel independent. Serial signal baud rate can be detected automatically by SFT/R-D-13.

Main Feature:
1. Multi-mode 2KM, signal-mode 20KM (Max. distance up to 80km)
2. Transparent transmission, support any baud rate (from 0 -115, 200bps)
3. Using TDM technology, Rs232/Rs422 or Rs232/Rs485 Parallel transceive
4. 15KV static protection
5. Each channel endure 10/700us 4kV Thunderstroke testing
6. Supply single fiber and double fiber.
