Claim 0:
1. An optical fibre ribbon (100) with intermittent bonding, the optical fibre ribbon (100) comprising:
a plurality of optical fibres (102), wherein the plurality of optical fibres (102) are placed parallel to each other, wherein the plurality of optical fibres (102) adjacent to each other are bonded intermittently along a length, wherein the optical fibre ribbon (100) has a bond ratio between 15 to 22, wherein the bond ratio is a ratio of a number of plurality of bonds (106) per unit length of the optical fibre ribbon (104) to a number of optical fibres in the optical fibre ribbon (100),
wherein each of the optical fibre of the plurality of optical fibres (102) comprises a plurality of bonded portions (104) and un-bonded portions (108), wherein the plurality of optical fibres (102) are placed in contact with adjacent optical fibres,
wherein the optical fibre ribbon (100) passes a twist test when a load of 500±25 grams is applied on the optical fibre ribbon (100) of length 300±10 millimeters to rotate the optical fibre ribbon (100) at 180±10 degrees in each direction for at least 20 cycles at 10 to 20 cycles per minute.
