ANTICOUNTERFEITING MEANS FOR OPTICAL COMMUNICATION COMPONENTS
First Claim
1. A transceiver comprising:
- a transmitter optical subassembly;
a receiver optical subassembly;
a controller operably connected to the transmitter optical subassembly and the receiver optical subassembly; and
a memory module operably connected to the controller circuit and having a key stored therein,wherein the controller circuit is adapted to authenticate the transceiver by receiving challenge data from a host device and sending encrypted response data to the host device using the key.

Abstract
Methods and systems for detecting counterfeit optical communications products are described. An exemplary system includes a host device and a fiber optic component, such as an optical transceiver. The optical transceiver may include a TOSA, a ROSA, a controller circuit, and a memory module. The controller circuit may be operably connected to the TOSA, the ROSA, and the memory module. The host device may send a set of challenge data to the optical transceiver. The optical transceiver may respond with a data set encrypted by the controller circuit using a secret key stored in the memory module. The encrypted response data set may be evaluated to determine whether the optical transceiver is authenticate.
