Wave Solderable Dual-in-Line Package

Description

The OPF0400 series is a cost effective solution for 850 nm

fiber optic link designs. The transmitter and receiver pair are

designed for use with multimode optical fiber with either

50/125µm or 62.5/125µm diameters. This fiber optic pair is

housed in a space saving, auto-insertable package that is

compatible with most wave solder processes.

Receiver

OPF2416 is a low cost solution for high speed, fiber optic

communications designs. The internal lensing of this re-

ceiver’s design allows optimal response from fiber sizes of

100µm and below.

The receiver is comprised of a high speed, low noise, photodi-

ode coupled to a transimpedance amplifier (TIA). The photo-

diode/TIA combination produces an output voltage that is pro-

portional in the input light amplitude. This hybrid approach

solves many of the problems of high speed data link designs

by placing the photodiode close to the TIA. The amplification

of the TIA makes the output much less susceptible to EMI.

The output of the OPF2416 is an analog, low impedance,

emitter follower voltage source. Subsequent circuitry can

utilized to convert the analog voltage to ECL/TTL for digital

data rates up to 155 Mbps.

The OPF2416 is available with either standard or threaded

available in conductive plastic. Refer to the part number

guide for more details.
