LTSW-2a Optical Switch （Rev 1.0）

Overview        The LTSW-2a optical switch can be used as an automatic switch for backup optical transmitters in optical fiber networks. It can automatically switch to the standby optical circuit to maintain optical signal transmission in case of failure and interruption of the main optical or RF signal. This product selects imported high-performance switching devices, while optional radio frequency signal monitoring function, to ensure the normal network transmission signal, built-in perfect embedded automatic monitoring system, to ensure the excellent performance of the whole machine. Features         ● Used for wavelength of 1550 nm, 1310 nm
        ● Low insertion loss
        ● High isolation, short switching time
        ● Input optical power range is large
        ● With RF monitoring function
        ● Supports automatic/manual mode switching
        ● Automatic switchover threshold User ,it’s adjustable for user
        ● In automatic mode, support dual detection of optical power input and RF output
        ● Perfect protection circuit
        ● Complete LCD display control and network management interface, convenient for local and remote control
        ● 1U height standard rack Technical parameters
