*2: Measured with the recommended driver circuit shown below.
(Vcc=4.75 to 5.25 V, R1=180
, R2=470 , R3=10 , C1=47 pF)
*3: Input is a pseudo-random bi-phase signal at 125 Mbps (NRZ signal conversion).
*4: Average value (duty ratio 50 %) measured by using a plastic fiber of
φ1 mm. SI-POF and NA=0.5 (GH4001 made by Mitsubishi
Rayon).
Note)
A bypass capacitor (0.1 F) and another capacitor (4.7 F) are connected between Vcc and GND at a position within 3 mm from
the lead.
The center of the optical fiber is aligned with the center of the lens on the package. The distance between the fiber end and the
lens is 0.1 mm.
