Protokraft has announced the availability of its Direct 9 Series of high speed optoelectronic solutions that improve optical network performance and reliability in harsh environment applications. Protokraft teamed with Sabritec; one of the world’s leading suppliers of military / aerospace interconnects; to offer a high performance DB-9 / ARINC 801 based optical component solution for harsh environment fiber optic communications applications.

Protokraft has introduced the Direct 9 Series of high speed optoelectronic solutions with Sabritec’s DB-9 / ARINC 801 optical interfaces, designed for military, aerospace, industrial or utility applications where significant levels of shock, vibration and extreme temperature ranges are experienced. The Direct 9 optoelectronic transceivers integrate the functions of optical transmitters and receivers into the shell of a standard DB-9 connector. These components are ideal for use in harsh environments where small size, weight reduction and resistance to harsh environments are valued.

Protokraft Direct 9 series high speed optoelectronic solutions consist of fiber optic transmitter and receiver functions integrated into a DB-9 shell with a Sabritec ARINC 801 optical interface. The Direct 9 series optoelectronic transceivers are intermateable with Sabritec ARINC 801 DB-9 connectors.

The optical transmitters are high performance 850nm VCSEL's. The optical receivers consist of GaAs PIN and preamplifier assemblies and limiting post-amplifiers. The optical interface to the Direct 9 series optical transceivers is a Sabritec ARINC 801 DB-9 connector enabling interconnection to optical fiber cable assemblies.

The electrical interface to the Direct 9 series optical transceivers is a nine position solder pin field facilitating easy interconnection to printed circuit cards, backplanes or flexible printed circuits. The transmitter input lines are driven with differential CML, LVDS or LVPECL signals applied to the Transmit (TX+ and TX-) pins. The optical receivers consist of PIN and preamplifier assemblies and limiting post-amplifiers. Electrical outputs from the receivers consist of differential CML, LVDS or LVPECL data signals on the Receive (RX+ and RX-) pins and single ended CMOS or LVPECL signal detect functions with output squelch on the Loss of Signal (LOS) pins.
