OCTP Series Scanner Chapter 4: Installation
4.2.2. Connecting the Optical Fiber
ATTENTION
When installing the fiber, make sure that the fiber tip does not get contaminated by dust.
Thorlabs' Fiber Inspection Scope (Item # FS201) and Fiber Connector Cleaner (Item # FBC250)
are useful for keeping the optical path clean.
Do not touch the fiber tip!
Attach the optical fiber from the OCT base unit to the OCTP, as illustrated in Figure 22. Either end of the fiber
patch cable may be used to connect to the OCTP. Remove the dust cap from each fiber end and store these
with the system packaging. The OCTP's FC/APC fiber connection is located at the fiber collimation module, as
shown in Figure 16. Insert the fiber tip into the center bore of the fiber connection, then secure the tip by rotating
the locking cap clockwise.

The fiber connector needs to be oriented such that the alignment key slides into the key slot of the fiber
connector. If the key is NOT properly aligned with respect to the key slot, you will still be able to screw in the
fiber connector, but significant light intensity losses will result from this incorrect connection. The position of the
fiber connector also affects the OCT focal position (and the state of polarization for the OCTP-PS).
Follow the same procedure to connect the fiber to the OCT base unit. This step is not applicable for OCTP-PS
scanner. A step-by-step procedure is shown in Figure 23.
