Fiber modem can be connected with computer or other devices via Lotus screw type terminal. This is a small and flexible device which can solve the problem of traditional RS232 communication conflict between distance and rate.

Features

• Data transmission rate 0-115.2Kbps auto-adapted;
• Transmission distances:multi- mode optical fiber <2 Km,
• single mode optical fiber 20 km, 40 km, 60 km, 80 KM, 100 KM, 120 KM;
• wavelength: multi- mode optical fiber 850 nm /1310nm or DFB 1550 nm;
• single mode optical fiber 1310nm/1550nm
• fiber connector: SC/FC (for option)
• RS-232 connector type: Lotus screw type terminal
• Mix of interfaces can be ordered, like 2 x RS-232 + 2 RS-485 + 4 x RS-422 and so on
• TX and RX with LED alarms;
• Both types – Synchronous and Asynchronous ports are supported
• may construct network topological structure such as star type and chain type;
• complete transparent communication, not need for any debugging, plyg & play;
• optical power is stable and reliable with integrated light-receiving and transmitting module
• unique serial port for circuit protection, supporting hot-plug and swap;
• complete insulation of two terminals of transmission, anti- electromagnetic interference, lightning protection;
