The present disclosure belongs to polymercaptan compounds and application fields thereof, and particularly relates to a polymercaptan compound and a preparation method thereof, a curing agent, a resin composition, an adhesive and a sealant. The polymercaptan compound is represented by formula (I), wherein R, R, R, R, Rand Rare each independently selected from one of a hydrogen atom, an alkyl group with 1-5 carbon atoms and an alkoxy group with 1-5 carbon atoms, Rand Rare each independently selected from an alkylene group with 1-5 carbon atoms, and m and n are each independently 0, 1, 2 or 3.

Polymercaptan compound and preparation method thereof, curing agent, resin composition and use thereof

An integrated optical-amplification module includes a housing member, a first input optical terminal configured to receive an optical signal, a second input, optical terminal that can receive a pump light, and an output optical terminal that can output a combined optical signal comprising at least a portion of the optical signal and a portion of the pump light. The integrated optical-amplification module also includes an optical combiner fixedly installed relative to the housing member. The optical combiner can receive the pump light and the optical signal and an optical prism fixedly installed relative to the housing member. The optical combiner can merge the pump light and the optical signal to form the combined optical signal. The optical prism can direct at least a portion of the optical signal through free space to the optical combiner.
