XFP-based hot pluggable analog optical receiving module

The invention discloses an XFP-based hot pluggable analog optical receiving module comprising an optical receiving device unit, a coupler, a Balun converter, an impedance matching circuit, a power detector, an LDO chip, an optical power detector and a single-chip microcomputer. With application of the analog optical receiving module, the size is small and the cost is low so that replacement, maintenance and intellectualization of equipment are facilitated.
