Red LED for optical link
L10881
RC-LED for 156 Mbps POF communications
The L10881 is designed for high-speed POF (plastic optical fiber) communications. The device is molded into miniature plastic
package with lens, allowing easy and efficient coupling to a POF.
Features
Applications
Red RC-LED for POF data link
Plastic optical fiber communications (FA, office machine,
home automation, LAN)
Data transmission in locations subject to high
electromagnetic noise
Peak emission wavelength: 650 nm
(suitable for POF communications)
High-speed response: fc=70 MHz Typ.
High output power: Po=-2 dBm (IF=20 mA, φ1 mm, POF)
Designed to be used with the S7727

Input is a pseudo-random bi-phase signal at 156 Mbps (NZR signal conversion).
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).
Vcc=5.0 V, R1=100 Ω, R2=300 kΩ, C1=20 pF
Note:
· A bypass capacitor (0.1 μF) and another capacitor (4.7 μF) 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.
· When using optical fibers with small core diameter, the fiber-coupled optical output power may vary.
