| Description
OPR-M24/M24-WD is a CATV optical receiver module, which is installed in the ONU device to convert optical signals into RF signals for use in the TV set-top box.
OPR-M24 receives optical signals in the wavelength range 1210nm~1610nm.
OPR-M24-WD receives optical signals in the wavelength range 1550nm. rings out 1310/1490nm data for PON.
Both modules have IIC communication functions, which can help users to monitor and control module parameters remotely easier.
