Part No. MDE7725-nnn	Quick and easy mechanical coupling of two bare fibres without splicing Can be used with index matching gel to minimize coupling loss Includes V-block clamps

“BUTT-MAN” is designed to allow two bare fibres to be coupled quickly and easily without the need for splicing in applications such as OTDR testing. Typical losses are 0.8dB (0.3dB best). Each fibre is initially gripped in the outer thumb-loaded clamps. The left hand clamp moves smoothly along the X-axis moving the fibre along the V-groove into contact with the fixed fibre. This movement can be clamped if required. Index matching gel can be used in the V-groove to improve the coupling efficiency. Once aligned, the two central V-block fibre clamps can be used to hold the fibre ends firmly in the V-groove while a measurement is made.
