OS2 MPO To 4 LC Duplex Breakout Cable

OS2 MPO to 4 LC Duplex Breakout Cable

Specify a single-mode fanout when one multi-fiber distribution port must serve four duplex LC circuits. Glory Optical's OS2 MPO to 4 LC Duplex Breakout Cable carries eight G.657.A1 fibers through a 30 m double-jacket trunk. The distribution end is a female MTP®-8 APC interface; the equipment end presents four LC UPC duplex Uniboot connections.

Glory MPO/LC series reference: pictured multimode six-duplex assembly. This page specifies an OS2 four-duplex cable; fiber grade, connector finish and branch count follow the confirmed order.

A Single-Mode Schedule for Four Duplex Circuits OS2 9/125 μm · 30 m · 8 fibers · female APC multi-fiber end · 4 LC UPC duplex ends · Type B Choose the common trunk for the distribution route and reserve the individual LC legs for the final port assignments. Both optical faces in each duplex branch belong to the same circuit, giving four independently documented two-fiber paths.

Rated OS2 Configuration and Optical Limits

Apply each loss limit to its stated connector format using the agreed measurement procedure. Assess the completed optical path with its other mated interfaces, distribution hardware and fiber sections included in the channel budget.

One APC Multi-Fiber End, Four UPC Duplex Ends

Connector alignment illustration (FOA). Gender and keying are shown; polish is specified separately.

Check Gender and End-Face Geometry Independently At the distribution side, select a pinned mating connection suitable for the specified female APC end. The guide holes receive the counterpart pins; the adapter's key arrangement and port orientation must also match the planned route. At the four destinations, the LC optical faces use UPC polish. Confirm matching LC UPC receptacles on the selected equipment. The cable's APC and UPC designations refer to different ends of the same assembly and must remain distinct in the port schedule. Record the actual receptacle type before allocating stock. Housing color can assist identification, but interface records and the approved assembly drawing establish the required gender, polish and fiber layout.

How the Multi-Fiber End Is Assembled

Follow the Load Path from Housing to Cable Exit The keyed outer housing retains the connector at the distribution interface. Inside, the ferrule carries the populated fiber positions and works with a spring-supported internal mechanism to form the optical connection. The diagram includes pin spacers and clamps for different connector variants. Use it to understand the hardware families; the eight populated fibers and APC finish are established separately by the OS2 specification. The rear retention and boot support the transition into the cable. Release the connector using its intended latch mechanism and support the cable behind the boot when routing or changing a connection.

Assign Four LC Circuits Before Patching

Each duplex connector groups two LC ferrules into one endpoint. Across the assembly, four endpoints account for eight optical paths. Give each pair a circuit identifier tied to its rack, equipment and port; specify any production branch numbering in the order record.

The A–D entries above are planning identifiers, not a claim about factory label characters. Obtain the end-to-end fiber-position drawing to associate every multi-fiber position with its destination LC ferrule. Verify the complete Type B arrangement through any additional passive components.

Integrate the Fanout into the Distribution System

Modular distribution concept (FOA). This diagram shows system architecture; the four-LC cable geometry is defined in the order drawing.

Start with the Single-Mode Distribution Interface A suitable cassette or distribution adapter can place the multi-fiber interface at the managed patching point. Review its internal wiring, single-mode fiber specification and pinned APC mating connection as part of the same design. Take the four LC UPC branches to their assigned single-mode equipment ports. Decide where the fanout transition will sit so the individual legs reach the ports without hanging across adjacent hardware. Use the MPO panel and cassette range to discuss the mounting arrangement. Confirm the exact loaded interfaces and fiber mapping rather than treating the panel enclosure alone as the optical specification.

Measure the Managed Route and the Two End Transitions For cabinet-to-cabinet or zone wiring, measure the supported pathway together with both end access areas. The nominal assembly length is 30 m, with stated breakout lengths of 0.84 m at the multi-fiber side and 0.91 m at the LC side. The double jacket surrounds the shared cable section, while 2.0 mm branch legs allow the final terminations to be organized individually. Choose supports that protect the sheath and keep the connectors accessible for inspection and removal. Review equipment locations and the expected service moves with our fiber cabling project team. Define any changed transition length or cable construction on a separate drawing.

Select Optics for the Complete Single-Mode Channel

Use compatible single-mode optical modules at the two ends of each circuit. Optical wavelength, transmit/receive characteristics, interface polish and the full loss budget determine whether the planned equipment connection is suitable. The cable passively routes the fibers; a split-port application additionally requires the appropriate module lanes and host configuration.

Keep the 30 m cable length separate from the equipment's permitted system reach. At the stated maximum fiber attenuation, the glass contribution over 30 m is approximately 0.0105 dB at 1310 nm or 0.0063 dB at 1550 nm. Those calculated values exclude connector and distribution-component losses.

Installation Allowances for the OS2 Cable

The finished assembly has its own routing limits: 10 times the cable diameter during movement and 5 times the diameter when stationary. With the specified main-cable OD range of 3.6–4.5 mm, that gives 36–45 mm moving and 18–22.5 mm stationary. Check the delivered diameter and the requirements of each transition area on the drawing.

The 10 mm glass-fiber radius is a separate fiber rating. Lay out the jacketed route using the finished-cable allowance. Sustained and short-duration tensile ratings are 100 N and 300 N; establish an installation method that transfers load through suitable cable support rather than through the LC bodies.

Select the OFNP double-jacket assembly for the confirmed indoor installation requirement. The stated operating range is −10 to +60°C, with storage from −10 to +70°C. Include any unusual pathway exposure or handling condition in the configuration review.

Accept the Eight Optical Paths with Traceable Results

Inspect One Multi-Fiber Face and Eight LC Ferrules

Prepare tools for both connector formats and for the specified APC or UPC face. Inspect and clean the interfaces before making a connection, including the equipment-side mating faces. Keep the other LC pairs protected while a single circuit is being installed or tested.

Separate Wiring Verification from Loss Measurement

First trace continuity from the female multi-fiber end to every LC endpoint and compare the result with the approved Type B position map. Then test with suitable single-mode reference leads, agreed wavelengths and a documented reference setup. Retain results against the circuit identifiers used in the rack schedule.

The OS2 connector criteria are MTP® insertion loss ≤0.35 dB and return loss ≥65 dB, with LC insertion loss ≤0.20 dB and return loss ≥55 dB. State whether the requested report covers individual interfaces or the installed end-to-end channel so acceptance records can be interpreted correctly.

Coordinate the Cable with the Rest of the Rack

Information Needed to Release an OS2 Order

Send your four-circuit port list with the proposed distribution hardware to Glory Optical. We can review the interface requirements and confirm the drawing, sample and supply details before the configuration is released.
