Plastic Fiber Optical Data Link
LD Series
sFeatures
1. Low pulse width distortion.
2. This is a TTL and CMOS compatible interface.
(Direct coupling permitted to 74LS and 74HC)
3. Full-lock connectors in which the optical connectors use a lock lever in the
fastening mechanism.
4. POF (all-plastic fiber) is used.
5. The fiber wiring method is crimping by means of a special tool (LD-T1) which
does not use adhesive. (The special tool is available separately.)
6. Ferrules are of a simple structure and are low cost.
7. Types
Optical connector
Optical transmission module
LD-type optical data link
Optical receiving module
Optical fiber with optical connectors attached
sApplications
Between equipment such as audio/video, factory automation, and office equipment, and short data links
such as transfer systems within equipment.
