Infineon Technologies AG has released a family of fiber-optic transceiver modules that feature "intelligent" capabilities to allow efficient, accurate, and reliable performance monitoring of an optical link.

The iSFP modules are fully-compliant with the SFP MSA and provide an enhanced digital diagnostic monitoring interface based on the SFF-8472 specification. This allows real-time access to such operating parameters as laser bias current, transmitted/receiver optical power, internal transceiver temperature, and supply voltage.

The iSFP modules also feature internal calibration of measurements over operating temperature, as well as built-in alarm and warning threshold sensors that allow the user to determine when a particular value is outside of its operating range.

The devices operate over the extended temperature range and support a data rate of up to 2.5Gbps. They also exhibit low EMI performance and high jitter performance.

Infineon has also released its second generation 12-channel Parallel Optical Link (PAROLI) family and features a single-channel data rate of 3.125Gbps. The devices offer a total throughput of 37.5Gbps and consume <1.4W. They are designed for use in multi-processor architectures, high-speed switching systems, and SONE and GbE backplanes.
