A novel architecture to enable future network security systems to provide effective protection in the context of continued traffic growth and the need to minimize energy consumption is proposed. It makes use of an all-optical prefiltering stage operating at the line rate under software control to distribute incoming packets to specialized electronic processors. An experimental system that integrates software controls and electronic interfaces with an all-optical pattern recognition system has demonstrated the key functions required by the new architecture. As an example, the ability to sort packets arriving in a 42.6 Gb/s data stream according to their service type was shown experimentally.

This paper presents an overview of PIC transceivers studied for ATM-PON systems. The demonstration of the FSAN class B and C specifications, fulfilled by an in-line PIG, is reported as well as the development of a connectorised TO module developed in the frame of a RNRT project (TANIA).

A -29.5 dBm sensitivity was measured, in full-duplex operation at 155 Mbit/s, by using an in-line transmit-receive-device. The evaluation of a coaxial package demonstrates the interest of this very simple approach for the mass production of low cost modules.

The authors report, for the first time to their knowledge, a full-duplex sensitivity of -27 dBm at 155 Mbit/s (RX)-54 Mbit/s (TX) which meets system requirements with an in-line transceiver assembly using a commercially available transimpedance amplifier.
