Extrinsic .In fiber optic sensing, when the transducer is external to the fiber it is referred to as extrinsic sensing. This occurs when the fibers are only recognizing and transmitting the sensed information.

Distributed Sensing

August 16, 2011

The ability to adjust transmission properties of optical fibers externally was a groundbreaking discovery for optical sensing technology. This distributed sensing is unique to fiber optic sensing technology and allows for measurements over very long distances. In addition to this capability, the optical sensors transmit data using light, not electrical currents, which makes the transfer a stable process and eliminate any need for power supply.

XENPAK history

August 15, 2011

The XENPAK MSA was publicly announced on March 12, 2001 and the first revision of the document was publicly released on May 7, 2001. The most recent revision of the MSA, Issue 3.0, was published on September 18, 2002. The result covered all physical media dependent (PMD) types defined by the IEEE at that time for 802.3ae 10GbE.

XENPAK Description

August 15, 2011

XENPAK modules were supplied for physical layer interfaces supporting multi-mode and single mode fiber optic cables and InfiniBand copper cables with connectors known as CX4. Transmission distances vary from 100 metres (330 ft) to 80 kilometres (50 mi) for fiber and up to 15 metres (49 ft) on CX4 cable.
