fibers which connect with the spectrograph in the pier lab . The fibers are protected by an outer conduit , constituting the optical cable assembly , running the length between the telescope and pier lab .
In October , other engineers from AAO and Gemini ran some tests using a mock optical cable assembly to demonstrate how this cable would move , and to identify any potential problem areas , such as snagging , as the telescope changes positions ( Figure 8 ). These tests resulted in some minor design tweaks , and an overall confidence in the cable design . We expect the first delivery of GHOST subassemblies , Cassegrain unit , and cable assembly at Gemini South to occur in the fourth quarter of this year .
