OM4 MPO Multi-Connector Trunk Cable

OM4 MPO Multi-Connector Trunk Cable

Bring multiple OM4 circuits through one pre-terminated route. This Glory Optical trunk combines a double-jacket cable with individually connectorized Base-12 units, allowing the termination areas to accommodate the selected capacity from 12 to 576 fibers. Specify the UPC connector gender for each end, choose the insertion-loss grade, then establish the required wiring and cable length.

Interface illustration only. Cable color, pin arrangement and the quantity of connectors are determined by the ordered OM4 build.

One Route, Organized into 12-Fiber Terminations OM4 50/125 μm · UPC mating · 12–576 fibers · two loss grades · double-jacket cable Allocate a connector group to each planned destination port. Higher fiber counts add more connectorized units at both ends while retaining a common main-cable pathway. Select OFNP or LSZH to suit the installation specification.

OM4 Assembly Data and Orderable Options

Diameter and tensile loads vary across the available builds. Confirm the individual cable's dimensions and ratings on its released part drawing. Each loss grade is an orderable connector limit; the two listed values do not represent typical and maximum results for one grade.

Select the Loss Grade before Closing the Channel Budget

Choose a maximum connector insertion loss of 0.20 dB or 0.35 dB for the assembly. The selected grade applies at both the A-side and B-side; connector gender remains a separate choice for each side. Record the grade on the purchase specification so optical results can be checked against the correct limit. The minimum connector return loss is 27 dB.

Evaluate the complete multimode path using its length, all mating interfaces and any modules or patch leads. The fiber attenuation limits are 2.3 dB/km at 850 nm and 0.6 dB/km at 1300 nm. Use the appropriate wavelength and test procedure for the intended equipment; the connector rating alone does not establish an application's permitted reach.

Turn Fiber Capacity into a Port Schedule

One Base-12 termination carries twelve fibers. Divide the selected total by twelve to obtain the number of connector groups on each side. A unique group identifier should follow that unit from the first termination area to the second, with the fiber-position correspondence captured in the wiring record.

A 96-fiber build provides eight groups per side; a 288-fiber build provides twenty-four. Reserve enough panel positions and management space for the chosen quantity. For the smallest 12-fiber selection, the assembly has a single multi-fiber connector at either end.

Define the UPC Interface at Every Connection

General mating geometry. Check the ordered UPC interfaces and gender against the actual ports used in the installation.

Separate Gender, Key Orientation and Fiber Routing Guide pins identify a male interface; the complementary female interface has guide holes. Review the mating partner for each end rather than choosing gender from the cable name or the housing color. Specify UPC at both sides of this OM4 assembly. Confirm the adapter key arrangement and connector access before finalizing the end details, particularly where several grouped units terminate next to one another. Type A, Type B and Type C are selectable routing arrangements. Choose the map that completes the required transmit-to-receive paths through the connected equipment and passive hardware, and retain that map with the cable identifier.

From the Shared Cable to the Connector Ferrule

Component overview with alternative pin hardware. It illustrates connector construction rather than the exact parts list of the finished trunk.

Provide Space for the Branches and Release Housings Inside each termination, the ferrule locates the optical fibers while spring and retention components support the mating assembly. The keyed housing positions the connector at its port; the boot manages the transition to the branch cable. The trunk divides into 2.0 mm branch units with a stated fanout length of 0.84 m. Locate the transition so those units reach their assigned ports without placing tension on the connector boots. Service access matters when the group count increases. Arrange identification and branch routing so a technician can read a label, inspect the interface and operate the release without disturbing adjacent circuits.

Plan the Distribution Route around the Optical Circuit

Modular distribution example. The selected modules must support the OM4 fiber category and the specified trunk interfaces.

Distribute Capacity through Compatible Modules A connector group can feed a suitable distribution module when its gender, UPC geometry and internal position map match the design. Map the equipment-side duplex ports to the trunk fibers before assigning module labels. Review MPO patch-panel options together with the module population. Include branch storage, rear connector access and the total group quantity in the cabinet plan. Duplex equipment connections require the appropriate modules or separately specified MPO-to-LC breakout assemblies. Confirm their OM4 configuration and pairing as part of the same circuit schedule.

Optical-path illustration. Active-fiber usage, distance and data rate follow the chosen multimode equipment and channel design.

Check Fiber Usage before Assigning Parallel Links For equipment with multi-fiber optical ports, verify the exact connector, pin arrangement and occupied fiber positions. A twelve-fiber cable group does not mean every fiber is used by every optical interface. Trace the proposed channel through each patching point. Account for the selected loss grades, cable attenuation and the other passive components when checking it against the equipment's optical budget. Our data center connectivity team can review the proposed path using the equipment list, group schedule and measured route.

Route the Finished Cable to Its Own Bend Limits

The 7.5 mm minimum radius describes the glass fiber. For the jacketed assembly, allow 20 times the main-cable diameter during movement and 10 times that diameter once installed. Determine D from the ordered construction, whose trunk diameter lies within the 3.6–21 mm family range.

Plan the route length from the actual termination locations. Preset selections include 2, 3, 5, 10, 15, 20, 25 and 30 m, with custom length available. Mark the overall-length reference points and the fanout transitions on the drawing so installation staff can position the cable consistently.

Pulling protection is selectable at the A-side, B-side or both sides; a build without a pulling eye is also available. Check that the pathway accommodates the protected connector bundle and establish how force transfers to the assembly during the pull.

Construction-dependent tensile ranges are 100–200 N for sustained loading and 300–660 N for short-term loading. Obtain the specific build's allowable values before installation, and secure the cable at its intended supports after routing.

Use the Temperature Range for the Selected Jacket

Include the required jacket type in the order rather than selecting it from the illustration. Match the material choice to the project's installation requirements, then use the corresponding temperature limits for handling, storage and service planning.

Accept the Assembly by Group and Loss Grade

Identify, Inspect and Trace

At receipt, reconcile the total fiber count and connector quantities with the schedule. Check the end labels and gender, inspect the optical faces and verify continuity against the approved position map. Clean and re-inspect an interface when its condition requires it before making the connection.

Retain Multimode Measurement Details

Define the multimode launch conditions, reference leads, measurement wavelengths and acceptance method before testing. Associate each result with its cable, connector group and fiber position, and compare it with the ordered insertion-loss grade.

Keep component measurements and the installed-channel assessment in the project records. The latter includes the complete routed length and all passive connections that the operating signal will encounter.
