LED-optical fiber coupling
PD-LD

The PLD-1315 and PLD-231X Series are designed to be backward compatible with industry standard sources and detectors used for single mode fiber applications. This form factor allows designers to offer single mode fiber performance in applications which currently use short wavelength (850 nm) devices in identical form factor packages . A link upgrade from multimode to single mode fiber can be done as easily as swapping out the optical components on the printed circuit board.

TRANSMITTER

The PDL-1315M/TM is constructed using a 1300 nm Edge Emitting LED (ELED) . Such ELED’s efficiently couple their optical output into single mode optical fiber. Although a single mode emitter, driving the ELED can be done with the same circuitry used with multimode LED based components. Such circuitry is much simpler than that used with LASER based emitters given that no optical feedback is required with an ELED.
