As  the number of Fiber-To-The-Home (FTTH) subscribers increase, there is  an increased awareness of the importance on construction for connecting  the “drop” as well as the indoor connection. Traditionally the  connection is done with the mechanical splice at the outdoor cabinet or  inside room of subscriber's house. It requires operators to take much  care and time to handle 0.25mm diameter fiber.The following are some general opinions and assumptions of our analysis:
-         Indoors,  controlled environments such as Central Offices/Head-Ends, LAN/Inside  the Building (horizontal and riser), have tended to not use field  installable fiber optic connectors; however, as technician skills  improve as well as the products becoming more “fool-proof” there will be  a continued increase in field installable fiber optic connectors.
-         Military/Aerospace, Specialty, and modules/components relatively use less field installable types.
-         Outdoor  environments such as undetermined-length Telecommunication links  (FTTx), some CATV links and LAN-to-LAN (or LAN) Building-to-Building,  Campus links relatively incorporate more field-installable fiber optic  connectors.
