H9925

H9925 is a type of bi-directional optical receiver with high performance, low cost and economical. It is applicable to various application of the HFC network fiber to the home (FTTH), and can provide high reliability analogue, digital video frequency and data bi-directional transmission for the HFC network.

H9925S: Single fiber bi-direction, built-in WD1315 CWDM.

H9925D: Dual fiber bi-direction, without CWDM.
