13.3.2. Loss expectations
Insertion loss and ORL values are recorded and included
with each indexing terminal. Refer to these for “chain”
performance expectation.
13.3.3. Cleaning
Refer to section 14.1 HMFOC cleaning
13.4. Restoral
13.4.1. Spare parts
Areas deploying fiber indexing terminals should consider
stocking a couple spare terminals for tear downs and dig-
ups. All four port indexing terminals are interchangeable
so stock a length that will cover your needs. Likewise, all
eight port indexing terminals are interchangeable. Index
only terminals are fiber specific but interchangeable in
relation to fiber count. As an example, if you have a 2f
indexing terminal it will interchange with all 2f terminals.
13.4.2. Splicing
Indexing terminals use 12f stranded flat drop. No special
splicing requirements. Suggest using GATOR splice
closure, FDSC-GATOR-12F-T.
