As a stable light-emitting equipment, LSU can provide optical signal source for power monitoring of the link in optical fiber monitoring systems. It cooperates with monitoring equipment at the opposite end to achieve real-time monitoring of the optical power. LSU uses the DFB laser internally, which is characterized by good light stability, high luminous power, long working life, etc. In addition, it is designed for maximum configuration flexibility, with pluggable modules that plug directly into the FMT managed chassis, each module occupying one slot.
