OP815
3 of 16
Overview
The OP815 oers an economical approach for insertion loss measurements for either
singlemode cables or multimode cables. For the multimode testing the OP815 is
equipped with an 850nm LED, a 1300nm LED or a switched 850nm/1300nm dual
LED source. The sources for the single mode conguration consists of Fabry-Perot
LASERs with 1310nm and 1550nm wavelengths. For all those models, the power
meter is equipped with a ber terminated InGaAs detector.
For specic applications, such as plastic optical ber (POF), the OP815 can be equipped
with various LED sources (480/630/650/850nm) with internal launch bers of various
sizes (50μm to 900μm). For lower wavelength sources the power meter is equipped with
a 3mm Si (silicon) detector.
Dual wavelength instruments: With dual wavelength instruments, that have a single
combined optical port, the sources are either internally switched (multimode) or optically
combined (single mode). With those instruments only one optical source is active at a
time.
OP850 (Multichannel IL Test Set)
The OP850 is similar to the OP815 in that it is primarily an insertion loss test set with a
source and a power meter. The OP850 is a multichannel version of the OP815. Both the
OP815 and OP850 have similar modes (OPM, IL, and SRC). These modes function the
same, but the only dierence is the front panel button behave a little dierent for the two
units.
