On the annular projection of said metal caudal peduncle rear end, be socketed with aluminum riveting spare, aluminum riveting spare overlaps simultaneously catches single core butterfly optical cable, increases the pulling force of single core butterfly optical cable and connector.
The optical property of the utility model butterfly optical cable jumping fiber requires:
Insert loss: the insertion loss (containing adapter) of arbitrary connector (plug)≤0.30d B (containing repeatability);
Return loss: the return loss＞50dB of arbitrary connector (plug).
The good effect of the utility model butterfly optical cable jumping fiber is:
(1) adopting hard optical cable---single core butterfly optical cable is made the connection optical cable, according to single core butterfly optical cable design feature (optical fiber is embedded in the optical cable, can not be free movable); The butterfly optical cable connector connects through adapter; After perhaps moving behind the ceramic insertion core, more effective to the protection of optical fiber, and also the cross-under line is convenient in construction; The influence that is not subject to extraneous factor (people, environment) causes bending, also can not cause the decay of signal;
(2) the butterfly sheath is connected with optical fiber closely with blue heart yearn; Not removable each other; The connector that is made up of ceramic insertion core, metal caudal peduncle, aluminum riveting spare, single core butterfly optical cable is mass activity with respect to the plastic cement inside casing; According to single core butterfly optical cable design feature, this protection to optical fiber is more effective;
(3) for fiber-to-the-home final stage provides a kind of ready-made, butterfly optical cable jumping fiber that need not field fabrication, bigger convenience is provided to the user.
