The Fiber Holding Blocks, Inserts, Lifting Levers, and Thumbscrews
The Fiber Holding Blocks (FHBs) are designed to accommodate a wide range of fiber buffer and cladding sizes
through the use of changeable top and bottom fiber holder inserts, which must be purchased separately. The bottom
inserts feature V-grooves and are available in three varieties. Insert options are outlined in the table below. The
VHD and VHF series of bottom inserts feature holes for vacuum to assist in loading the fiber when used in other
equipment such as the GPX family of splicers. The VHF series of Transfer Bottom Inserts are designed to work with
the VHT1 Transfer Clamps to aid in moving the fiber between compatible Vytran stations while maintaining coarse
alignment, allowing safe easy handling, and also providing accurate registration/repeatable lengths of the cleaved
parts. The VHE series of inserts have long extensions that allow the fiber to be held in place
by a user’s finger while
the FHB Lid is closed. Both the bottom inserts and the top inserts (which feature flat clamping areas) must be sized
according to the buffer/cladding diameter. Selecting the correct inserts ensures that full cleave tension can be
applied without the fiber slipping. All inserts are labeled with a nominal accepted diameter in microns. In the event
that you wish to use a fiber that is between insert sizes, refer to the chart in Section 9.1 to determine which inserts
would be most suitable or use the Insert Selection tool in Handset Controller.
