Ferrule part and optical communications module

A ferrule part comprising:

• a ferrule having first and second end faces and a groove, said first and second end faces intersecting a first axis, said groove extending along a second axis, and said second axis intersecting said first axis to form an acute angle, said groove being provided along a plane defined by said second axis and a third axis perpendicular to said first and second axes, said groove extending across said ferrule along said second axis, said groove having a pair of side surface extending along said plane;
• an optical part provided in said groove so as to intersect said first axis, said optical part having a pair of surfaces, said optical part being capable of transmitting a part of light incident on said one surface of said pair of surfaces of said optical part, and said optical part being capable of reflecting a part of light incident on said one surface of said pair of surfaces of said optical part;
• a first optical fiber supported in said ferrule, said first optical fiber having one end, said one end of said first optical fiber facing said one surface of said pair of surfaces of said optical part;
• and
• a second optical fiber supported in said ferrule, said second optical fiber having one end, said one end of said second optical fiber facing the other face of said pair of faces of said optical part;
• wherein said ferrule is made of material that is capable of transmitting light propagating in said first and second optical fibers,
• wherein said groove has a pair of side faces extending along said plane, wherein said ferrule has a hole extends in a direction of said first axis, and
• wherein said hole has first and second portions, said first portion extending from said first end face of said ferrule to said one side face of said groove, and said second portion extending from said second end face of said ferrule to the other side face of said groove,
• wherein said one end of said first optical fiber terminates at an end of said first portion of said hole and said one end of said second optical fiber terminates at an end of said second portion of said hole.
