The FOT-300 combines a source port and a power meter. It offers up to three singlemode or two multimode sources on a single port and transmits with a wavelength-identification digital encrypted protocol, so that any compatible unit—such as the FPM-300 Power Meter or another FOT-300 Optical Loss Test Set—can automatically use the proper calibration parameters. This reduces the need for communication between the two technicians and decreases the potential for error.
This product is part of EXFO's series of FTTx optical test products. It allows for the testing of passive optical networks (PONs) at the three main wavelengths (1310, 1490 and 1550 nm) used in fiber-to-the-home (FTTH) and fiber-to-the-premises (FTTP) networks and complies with the ITU-T G.983 and G.984 Recommendation series and the IEEE 802.3ah standard.
Signal encrypting can also give the receiving end information on the power to be used as reference, helping ensure efficient referencing, even when the two units are far apart.
Thanks to its unique design, the FOT-300 Optical Loss Test Set reduces measurement time in typical measurement situations, as the need for an offset nulling is eliminated.
