With black mini shutter system package and 5 PIN connection Toshiba TORX177PL Fiber Optic Receiving Module known
suitable use for Digital Audio optical Interface. Its 5 PIN connection
consist of Output, GND, Vcc, and two N.C. This device required optical
fiber with fiber optic connectors (all plastic fiber with square type connector)
Its PCB thickness recommendation is 1.6 mm. Here are little information sections within Toshiba TORX177PL Fiber Optic Receiving Module Datasheet
for such -40 to 70 C storage temperature, Output Current -1 to 5 mA,
Supply voltage -0.5 to 6 V, and 260 C soldering temperature with notes
less than 10 seconds in soldering at a distance of 1 mm from the package.
It is recommended 4.75 to 5.75 V of supply voltage for its operating conditions. In data rate
characteristics, it is said that when modulated optical high level
signal is received, output signal is high; when modulated optical low
level signal is received, output signal is low; when non-modulated
signal(optical all low or all high level signal) is inputted, output
signal is not stable according to the datasheet.
