Technical Field

The present teachings relate generally to connectors and adapters for dual fiber mechanical transmission type ferrules (ferule), and more particularly to miniature connectors and adapters, such as simplex, duplex, and quadplex miniature connectors and adapters having a remote release and a dual fiber ferrule.

Background

The popularity of the internet has led to an unprecedented growth in communication networks. Consumer demand and increased competition for services has led network providers to continually seek ways to improve quality of service while reducing costs.

Some solutions include the deployment of high density network panels. These panels are designed to integrate the increased amount of interconnection required to support the rapidly growing networks into compact spaces, thereby improving quality of service and reducing costs, such as floor space and supporting overhead expenses. A high-density network panel may contain a large number of ports to accommodate the large number of connections typically required to connect the network panel to a network switch or other network termination. The ports of the panel are typically designed to mate with a connector comprising two optical fibers, referred to herein as a dual fiber connector, where one fiber transmits data (Tx) and the other fiber receives data (Rx). A plurality of dual fiber connectors, such as six dual fiber connectors, from a network panel are typically combined together into a fanout jumper (jumper). In this design, the dual fiber connector and its fibers are coupled into a single cable, such as a 12 fiber cable, by a fanout block. Multi-fiber push on (MPO) connectors, such as 12-fiber MPO connectors, are typically mounted at the end of a single cable for connection to transceivers located at a network switch or other network terminal. The transceiver can then manage a large number of fiber and dual fiber connectors using fan-out jumpers and connect from the network panel to a large number of ports. However, the design, connector size, and connector accessibility of fan-out jumpers currently available have not been fully optimized for high density network panels.

A fan-out jumper with a dual fiber Tx-Rx connector may require a separate port for each Tx-Rx network connection; however, due to their design, they can present challenging and undesirable fiber management and maintenance issues for operators. For example, in a fan-out patch cord with one 12-fiber MPO connector and six dual-fiber connectors, the MPO connector activates all 12 fibers once inserted into the transceiver. However, this is convenient in the case where there are six Tx-Rx ports that need to be serviced simultaneously on the network panel. This may result in some or all of the six Tx-Rx ports being interrupted due to a failure of the MPO connector at the transceiver. Furthermore, whenever the MPO connector is unplugged for troubleshooting, repairing the MPO connector interrupts all 6 Tx-Rx ports, which may result in unnecessary service outages. Furthermore, if the network switch has a 12-fiber MPO type transceiver and only one network panel Tx-Rx port coupled to a dual-fiber patch cord connector needs to be serviced, this will result in five additional dual-fiber connectors being "active" but not being used from the cable patch cord. Unused but active dual fiber connectors then need to be stored with some length of dual fiber cable until future needs are fulfilled, which increases fiber management problems. Furthermore, a dual fiber connector from one 12 fiber MPO fan-out jumper may not be able to reach the Tx-Rx port on the network panel that needs service, in which case another transceiver would need to be powered up, while another 12 fiber MPO fan-out jumper would need to be added to the equipment rack. If the length of the 12-fiber MPO fan-out jumper were determined based on the Tx-Rx port furthest from the transceiver, there would be an excessively long dual-fiber connector cable to manage when servicing nearby Tx-Rx ports, again exacerbating the fiber management problem. It is most desirable to manage or "lay out" the cables in the horizontal and vertical cable troughs rather than crossing the equipment in a diagonal "short cut" as this can lead to equipment access and cable identification problems.

Some available ferrules and connectors may be designed to couple with fan-out jumpers and high density network panels, but their dimensions are not optimized for dual fiber applications. For example, MPO connectors are typically configured for 2 to 36 fiber optic ribbon cables, and are therefore much larger than required for dual fiber applications with the same fiber-to-fiber center distance of about 0.25 mm. The MPO connector was about 7.6mm high, 12.4mm wide, 25.7mm long (excluding the strain relief boot), and the front contact surface of the MPO ferrule was about 2.5mm high and 6.4mm wide. In contrast, MT-RJ connectors are configured for cables having fewer fiber optic ribbons, such as 1 to 4 optical fibers, but they are larger than the fiber optic ribbons required for dual fiber applications. The MT-RJ connector is about 10mm high, 9.2mm wide, 20mm long (excluding the strain relief boot), and the front contact surface of the MT-RJ ferrule is about 2.5mm high and 4.4mm wide. Furthermore, LC and SC duplex connectors can be designed for dual fiber applications, but their overall dimensions are not optimized to address the high density requirements of high density network panels. The LC duplex connector was about 12.7mm high, 12.8mm wide, 27.3mm long (excluding the strain relief boot), and the SC duplex connector was about 9.3mm high, 24.2mm wide, 25.2mm (excluding the strain relief boot).

For dual fiber patch cord connectors coupled to fanout patch cords and high density network panels, adjacent connectors and cable assemblies may obstruct access to the various release mechanisms at the Tx-Rx network panel ports. Such physical barriers may hinder the ability of the operator to minimize the stress placed on the cable and connector. These stresses may be applied, for example, when a user reaches into a dense set of jumper connectors with his/her thumb and forefinger and pushes the surrounding cables apart to access the individual connector release mechanisms. Over-tightening the cables and connectors can create potential defects, compromise the integrity and/or reliability of the terminal, and can result in significant network performance disruption.

While an operator may attempt to reach into the dense set of dual fiber jumper connectors and activate the release mechanism using a tool such as a screwdriver, the adjacent cables and connectors may obstruct the operator's view, making it difficult to guide the tool to the release mechanism without pushing the surrounding cables apart. Moreover, even if the operator has a clear line of sight, guiding the tool to the release mechanism can be a time consuming process. Therefore, using tools may not effectively shorten the support time and improve the quality of service.

Therefore, there is still a critical need for a better designed fan-out jumper to meet the requirements of high density network panels.

As discussed in more detail below, in some embodiments, the fiber optic cable may be modularly coupled with one or more fiber optic connectors, adapters, and other fiber optic cables using a remote release. Various aspects of the prior art and inventions are described below.

Those skilled in the art will appreciate that the apparatus and methods described herein are at least more suitable for dual fiber cable and high density network panel applications than the apparatus and methods described in the prior art.

For example, as shown in FIG. 1A, a conventional MPO connector 100 is typically configured for 2 to 36 fiber optic ribbon cables, and is therefore much larger than required for dual fiber applications with the same fiber-to-fiber center distance of about 0.25 mm. Conventional MPO connectors 100 are fitted with male MPO ferrules 102, as shown in fig. 1B, or female MPO ferrules 104, as shown in fig. 1C, having a front contact surface height 106 of about 2.5mm and a front contact surface width 108 of about 6.4 mm. Fig. 1D shows a front view of the conventional MPO connector 100 having a height 110 of about 7.6mm, and fig. 1E shows a side view of the conventional MPO connector 100 having a width 112 of about 12.4mm and a length 114 of about 25.7 mm.

In another example, as shown in fig. 2A, a conventional MT-RJ connector 200 is configured for use with cables having a smaller number of fiber ribbons, such as 1 to 4 fibers, but is larger than the cable required for dual fiber applications. The MT-RJ connector 200 mounts either a male MT-RJ ferrule 202 as shown in FIG. 2B or a female MT-RJ ferrule 204 as shown in FIG. 2C, the MT-RJ ferrule having a front contact surface height 206 of about 2.5mm and a front contact surface width 208 of about 4.4 mm. Fig. 2D shows a front view of the conventional MT-RJ connector 200 having a height 210 of about 10mm and a width 212 of about 9.2mm, and fig. 2E shows a side view of the conventional MT-RJ connector 200 having a length 214 of about 20 mm.

In another example, as shown in fig. 3A, a conventional LC duplex connector 300 is designed for dual fiber applications, but its overall dimensions are not optimized to address the requirements of high density network panels. The LC duplex connector 300 has a height 302 of about 12.7mm and a width 304 of about 12.8 mm. Fig. 3B shows a side view of a conventional LC duplex connector 300 having a length 306 of about 27.3 mm.

In another example, as shown in fig. 4A, a conventional SC duplex connector 400 is designed for dual fiber applications, similar to the LC duplex connector 300, but its overall dimensions are not optimized to address the requirements of high density network panels. The SC duplex connector 400 has a height 402 of about 9.3 mm. Fig. 4B shows a side view of a conventional SC duplex connector 400 having a width 404 of about 24.2mm and a length 406 of about 25.2 mm.

In another example, fig. 5B shows a plan view of a conventional 12-fiber MPO-6LC duplex fan-out jumper 502, which jumper 502 is often used to couple with high density network panels, and fig. 5A shows a front view of a 12-fiber MPO connector 506 attached at one end of the 12-fiber MPO-6LC duplex fan-out jumper 502. The 12-fiber MPO connector 506 includes six fiber pairs 520, 522, 524, 526, 528, and 530, each having one data-transmitting Tx fiber and one data-receiving Rx fiber. Twelve optical fibers pass through the cable 508 and are separated into a dual fiber cable 514 at the fan-out block 512. The dual fiber cable 514 has a length 516 and is terminated by an LC connector 518 that includes one of the fiber pairs 520, 522, 524, 526, 528, and 530.

Fig. 6 shows a perspective view of a conventional network equipment rack 600 and a 12-fiber MPO-6LC duplex fan-out jumper 500, such as may be found in central offices and data centers. The network equipment rack 600 includes: a plurality of network switches 602, including transceivers 604; and a plurality of network panels 606 that include a plurality of network panel ports 608. The network switch 602 and the network panel 604 are connected by a 12-fiber MPO-6LC duplex jumper 500. A 12-fiber MPO connector 506 (not shown) at one end of the 12-fiber MPO-6LC duplex fan-out jumper 500 is connected to the transceiver 604, and only four of the six dual-fiber LC cables 514 at the other end of the 12-fiber MPO-6LC duplex fan-out jumper 500 are connected to the network panel ports 608. The remaining two dual fiber LC cables 514 are not connected to the network panel ports because the desired panel ports 608a are inaccessible because the length 516 of the dual fiber cables 514 is too short. Thus, the 12-fiber MPO-6LC duplex fan-out jumper 500 is not optimized for high density network panels having network panel ports located at different distances from the 12-fiber MPO-6LC duplex fan-out jumper 500.

The latch spring is movably coupled with the housing 736, wherein at least a portion of the housing is movably positioned within the longitudinal channel of the latch spring 734.

The simplex micro-MT connector 700 may include a ferrule 738 extending longitudinally from a proximal end 746 to a distal end 748 and disposed at least partially within a longitudinal channel of the housing 736, with the proximal end protruding to the exterior through the channel defined by the latch body 730 and the housing.

The simplex micro-MT connector 700 may include a ferrule spring 740 defining a longitudinally movable passage therethrough from a proximal end 740a to a distal end 740 b. The ferrule spring 740 is at least partially disposed within the longitudinal passage of the housing 736.
