Attaching the heat sink to the 81628B
Optical Head
N O T E Always attach the heat sink and rubber ring to the 81628B if operating
at an optical power higher than 34dBm!
Applicable adapters
Agilent adapters types 81000xx, except the bare fiber adapter
(81000BA), are applicable with the 81628B and the heat sink attached
(without the heatsink and up to 34dBm the 81000BA bare fiber
adapter may be attached). Bare fibers are not intended to be used in
high power applications.
N O T E If shipping the 81628B high power optical head please detach the
heatsink from the optical head to avoid damages during
transportation.
Mounting Instructions
1 Check that the blue rubber ring is correctly attached to the
integrating sphere and covers the metallic screws as shown in
Figure 4.
Figure 4 Attaching the Rubber Ring
2 The heatsink consists of two conical metal parts, the bottom part
(smallest diameter at the bottom), and the top part (largest
diameter at top). Slide the bottom part of the heat sink over the
throat of the integrating sphere with the smallest diameter facing to
the sphere. Then screw on the desired adapter (81000xx series) to
the sphere as shown in Figure 5.
