Bayonet lock MPO connector
Optical fiber connectors for MT/MPO type ferrule assemblies are disclosed, having an overall connector length less than about 32 mm, for example, an overall length of about 18.5 mm for non-reinforced optical fiber cables, and an overall length of about 23.5 mm for reinforced optical fiber cables. In one embodiment, a connector comprises a ferrule assembly, and a housing coupled to the ferrule assembly and configured to couple to an adapter corresponding to the ferrule assembly. The connector further includes a lock coupled to the housing and configured to rotate so as to lock and unlock the housing from said adapter. An interface member coupled to the housing may include a stop configured to limit rotation of the lock. The interface member may include a reinforcement portion for reinforcing optical fiber cables.
1. A connector comprising:
a ferrule assembly;
a housing having a rear portion being configured to receive the ferrule assembly, the housing being further configured to couple to an adapter corresponding to the ferrule assembly;
a lock coupled to the rear portion of the housing and configured to rotate so as to lock the housing to said adapter;
the ferrule assembly disposed within the housing, wherein the housing includes at least one catch and the ferrule assembly is secured to the housing by the at least one catch of the housing; and
an interface member configured to limit rotation of the lock and having a reinforcement portion configured to reinforce an optical fiber cable received by the interface member;
wherein the housing includes at least one recess for receiving a catch of said adapter; and
wherein the lock includes at least one tab configured to cover the catch of said adapter disposed in the at least one recess of the housing when the lock is in a locked position.
2. The connector of claim 1 , wherein the ferrule assembly is one of an MT/MPO ferrule assembly and an MPO ferrule assembly.
3. The connector of claim 1 , wherein the lock is a ring configured to rotate about the housing.
4. The connector of claim 1 , the housing being the only housing of said connector.
5. The connector of claim 1 , wherein the lock is disposed about the rear portion.
6. The connector of claim 1 , wherein the lock includes at least one flexing tab configured to snap into a respective groove of the housing so as to couple the lock to the housing.
7. The connector of claim 1 wherein the ferrule assembly includes a raised flange and the housing includes a corresponding ferrule flange stop, the ferrule assembly being secured to the housing between the ferrule spring and the ferrule flange stop.
8. The connector of claim 1 , wherein the at least one tab is configured to uncover the catch of said adapter disposed in the at least one recess of the housing when the lock is in an unlocked position, to allow decoupling the housing from the adapter.
9. The connector of claim 1 , wherein the lock is further configured to rotate so as to unlock the housing from said adapter.
