LW-FM Series fiber modem is equipped with a multiple interface circuit that can handle RS-232 or RS-422/485 serial interfaces into multi-mode or single-mode fiber. They are used to extend serial transmission distance up to 2km(multi-mode fiber) or up to 20km (single- mode fiber). Note that the RS-232 and RS-422/485 interfaces cannot be used on the same model at the same time to convert to fiber . The LW305-RS Series incorporate a method for automatically detecting the serial signal baud rate by hardware. This is an extremely convenient feature for the user. Even if a device’s baud rate is changed, the signal will still be transmitted through the RS-232 or RS-422/485 to fiber converter without any problem. Lightwit Photonics company takes “Quality and Credit come first” as its base of exist and development. ISO9001 and CE assure the qualities for our customers,. Firmly through quality product line, effective research, manufacture and market management and with nearly a decade accumulation on industry insight and expertise, we have forged strong ties to customers from all over the world.
