Patent ID: 8660398

Claim:
An optical transition box ( 1 ) for housing an optical connection between a riser cable ( 4 ) and at least one drop cable of an optical access network, said optical transition box ( 1 ) comprising a base ( 2 ) comprising: a bottom ( 20 ) configured to house excess lengths of a first optical fiber of a riser cable ( 4 ) and of a second optical fiber of a drop cable; a first sidewall ( 24 ) positioned adjacent to said bottom ( 20 ); at least a second sidewall ( 21 , 23 ) adjacent to said first sidewall ( 24 ), wherein said first sidewall ( 24 ) forms with said second sidewall ( 21 , 23 ) a channel ( 25 a , 25 b ) suitable for housing the drop cable and for allowing the drop cable to exit said base ( 2 ); and a splice-holder element ( 26 ) fixed to said first sidewall ( 24 ) and overhanging from said first sidewall ( 24 ) above said bottom ( 20 ), said splice-holder element ( 26 ) being suitable for housing at least one splice between the first optical fiber of the riser cable ( 4 ) and the second optical fiber of the drop cable, wherein a distance not less than the diameter of the first optical fiber of the riser cable ( 4 ) is provided between said bottom ( 20 ) and said splice-holder element ( 26 ).
