For the loose tube of G.654.E optical fiber, an orange color bar is required for identification, and the orange tube plus a black color bar is identified. The width of the color bar is 1 to 3 mm. G.654.E fiber and G.652D fiber are not allowed to be mixed in the same loose tube.

The samples sent by the supplier pass all the test items and are judged to pass the test. One item that does not meet the index requirements is judged as unqualified.
