Description
Technical field
The present invention relates to optical transport technology field, and in particular to a kind of MPO/MTP boundlings prefabricated optical cable component.
Background technology
MPO is appellation of the Japanese NTT companies to bundling optical fiber connector, and MTP is USCONEC companies of the U.S. to bundling optical fiber
The appellation of connector.MPO is identical with both MTP operation principle and can be with compatible, and difference has at 2 points：One is
The spring of MPO plug insides is circular structure, and the spring of MTP plug insides is elliptical configuration；Two be MPO public plug guide pins
Top is cone, and MTP public plugs guide pin top is rugby shape.
The operation principle of MPO/MTP bundling optical fiber connectors is：The T-shaped aptamers alignment MPO/MTP of MPO/MTP public plugs is fitted
Plug is forcibly inserted into after the T-shaped adaptation groove of any one end face in orchestration two ends, hear " " sound is inside the T-shaped adaptation groove of adapter
The medial surface of left and right sides card leg clasped the grooves of the T-shaped aptamers both sides of MPO/MTP public plugs, while male plug end protective cover by
The lateral surface of the left and right sides card leg inside the T-shaped adaptation groove of adapter is wrapped up in the effect of spring and being locked so that public plug with
Can not pull-off after adapter coupling.Equally, T-shaped aptamers alignment MPO/MTP adapters other end on MPO/MTP females
Be forcibly inserted into plug after T-shaped adaptation groove, hear " " sound be the left and right sides card leg inside the T-shaped adaptation groove of adapter inner side
Face has clasped the groove of MPO/MTP female T word guide ways both sides, while female plug end protective cover is because the effect of spring is by adapter
The lateral surface parcel locking of left and right sides card leg inside T-shaped adaptation groove so that female can not pull-off after being coupled with adapter.
In coupling process, due to the positioning of the T-shaped adaptation groove of adapter, the guide pin on male plug end surface searches for alignment female plug head end automatically
Shrinkage pool on face simultaneously forms coupling.The T-shaped adaptation groove at adapter two ends is reverse.
Or the MPO/MTP boundling prefabricated optical cable components of prior art enter traveling optical signal biography between only limiting indoor communication device
Defeated connection, does not possess the anti-towing performance of shockproof dustproof and waterproof；A protection is simply increased outside MPO/MTP plugs outer
Public plug shell and female shell are rotated by 90 ° clamping by shell, fitted between certain dustproof and waterproof performance, plug though being possessed
