The FPM-8220 Fiber Optic Measurement Heads
The FPM-8220 is compatible with three fiber optic measurement heads:
FMH-8705 InGaAs, Fiber Optic Measurement Head, Detector Only (+1.5 to -85 dBm)
FMH-8715 InGaAs, Fiber Optic Measurement Head, Integrating Sphere (+20 to -70 dBm)
FMH-87107 InGaAs, Fiber Optic Measurement Head, Integrating Sphere (+30 to -60 dBm)
The FMH-8705 is a detector only measurement head designed to provide a low optical power
measurement range.
The FMH-8715 and FMH-87107 use integrating sphere technology to provide high accuracy
optical power measurements. More than a simple integrating sphere, the innovative integrating
cavity design in the FMH-8715 and FMH-87107 is the primary reason the FMH-8220 Fiber Optic
Power Meter is able to deliver excellent repeatability in a production workstation environment.
Key features of the measurements heads, and their benefits to you, include:
Feature Benefit
Minimal response to changes in the state of
polarization Measure loss due to polarization
without concern for meter errors
Minimal response to changes in fiber extension in the
holder Obtain the same results with different
users
Minimal response to rotating the fiber holder with a
non-angled cleave No need to rotate the fiber holder for
maximum reading with a non-angled
cleave
Bare fiber end face cannot contact detector surface Impossible to damage detector with
fiber
Bare and connectorized fiber measurements from the
same fiber end face position Compare bare and connectorized fiber
measurements with confidence
Production tested bare fiber holder easily guide the
fiber to the correct place every time No tedium to slow your testing or
introduce errors
Detector head designed to accept ILX’s BF-820 or
Agilent 81000BA bare fiber holders Use ILX’s BF-820 holder with Agilent
power heads or use Agilent’s
81000BA holders in the FPM-8220;
this interchangeability means that
there is no need to alter procedures,
or buy different holders
Precision quick-align, threadless adapters for most
connector type and the bare fiber holder Just push in or pull out; easily self-
aligns and snaps into place; no
threads
Protecting the FMH-8705 Fiber Optic Measurement Head
The fiber optic measurement head uses a 3mm detector that has been hermetically sealed in a
TO-Can package. To avoid accidental damage the plastic shipping protector should be installed
when a fiber optic adapter is not in use.
