Abstract: The present invention provides a converter unit (100) for convert a hardened connector (50) with small diameter into another hardened connector with large diameter such that the same hardened connector (50) compatible with two different types of fiber terminals i.e. small sized (new generation box) and large sized (old generation box). The converter unit (100) comprises an arrester unit (102) mounted over the small sized hardened connector via threaded lock, a shroud unit (104) coupled to the arrester unit (102) and a coupling nut (108) encapsulated over the shroud unit (104) to exhibit rotational and transaction movement over the shroud unit (104). Further, a first end (110) of the coupling nut (108) is restrained by the arrester (104) and a second end (112) of the coupling nut (108) being restricted by a shoulder (106) provided on the shroud unit (104).

Abstract: The present invention provides a hardened connector (100) for engaging at least one optical fiber (52) with an optical fiber terminal (70), the hardened connector (100) comprising: a first part (102), a second part (104), and a third part (106); the hardened connector (100) comprising an alignment mechanism (108) formed when at least two or the first part (102), the second part (104), and the third part (106) are engaged.

Abstract: The present invention provides a hardened connector (100) configured to engage with a port (52) of an optical fiber terminal (50) comprises a multi-part assembly (102) with protruded skirt (108) positioned between a front end (104) and a rear end (106); a first intermediate portion (110) positioned between the rear end (106) and the protruded skirt (108) and a channel (130) formed between plurality of extended fingers and a recessed portion (118) configured to receive a mating protrusion (56) provided in the port, thereby enabling alignment of the hardened connector in the port of the optical fiber terminal. The protruded skirt (108) and the first intermediate portion (110) enable locking of the hardened connector (100) within the port, when the front end of the hardened connector is pushed into the port.
