In addition, the sometimes harsh Andean environment meant that agriculture was viewed as a form of warfare so that, as the historian T. N. D'Altroy eloquently put it, The Incas approached farming with weapons in their hands and prayers on their lips (276).
Small Form-Factor Pluggable Transceiver (SFP) A small form-factor pluggable (SFP) transceiver is a compact, hot-swappable, input/output transceiver used in data communication and telecommunications networks. SFP interfaces between communication devices like switches, routers and fiber optic cables, and performs conversions between optical and electrical signals.

The first picture is a front view, which shows SFP module has two ports, one port has laser inside, which is the transmitter side. The other port has a photodetector inside, which is the receiver side.So basically, SFP is a transceiver module, since it has transmitter and receiver in a single unit.The second picture shows how SFP modules are used on PCB board. The right picture shows a perspective view of SFP module, so you can clearly see its mechanical outlines.he other port has a photodetector inside, which is the receiver side.
