Abstract: Fiber optic network systems are implemented, at least in part, using very small form factor (VSFF) interconnect components such as VSFF duplex connector; VSFF mechanical transfer ferrule (MT) connector; VSFF duplex uniboot connector; VSFF MT uniboot connector; VSFF duplex adapter; VSFF MT adapter; VSFF duplex pluggable transceiver; VSFF MT pluggable transceiver; VSFF patch cable assembly; VSFF trunk cable; and/or VSFF breakout cable. The VSFF fiber optic network systems can define fiber breakout cabling that connects large trunk cables to many peripheral network locations. The network systems can define branches and sub-branches from a trunk cable. The network systems can define cross-connect sub-networks between sets of transceivers or adapters. The network systems can define a trunk-to-transceiver cabling assembly for connecting a trunk cable to at least 32 transceiver ports.

Abstract: A multifiber ferrule has a generally forward-facing angled ferrule contact surface that is skewed with respect to the widthwise axis of the ferrule such that the angled ferrule contact surface defines a widthwise skew angle with respect to the widthwise axis. A multifiber optical connector has a connector housing assembly that holds at least one of this type of ferrule. The connector housing assembly can hold two such ferrules so that the ferrule contact surfaces are angled in opposite widthwise directions and so that a broad side of the first ferrule opposes a broad side of the second ferrule in parallel, spaced apart relationship therewith. A polarity-changeable multifiber optical connector is also provided that includes a multifiber ferrule with a generally forward-facing ferrule contact surface at an oblique angle to the longitudinal axis.

Abstract: An angle polished fiber optic connector adapted for connection with another angle polished connector in two, reversed configurations has a connector body and first and second angle polished ferrules. The first ferrule is supported by the connector body in a first fixed rotational position about the longitudinal axis of the first ferrule, and the second ferrule is supported by the connector body in a second fixed rotational position about the longitudinal axis of the second ferrule. The second fixed rotational position of the second ferrule being offset by 180 degrees from the first fixed rotational position of the first ferrule. A method of making an angled polished fiber optic connector that can be connected with different polarities is also disclosed.

Abstract: A converter with an outer housing having a first end and a second end. The first end further comprises a male, simplex fiber optic connector that is received by a test port of an optical signal tester. The second end of the converter has a port configured to accept an optical fiber connector with a first ferrule and a second ferrule with an optical fiber therein spliced to an incoming optical fiber with a signal from a network. The tester confirms the signal strength in dB when optical fiber connector is in test position “A” for the first ferrule and in test position “B” for the second ferrule.
