The OM4 MPO Multimode Fiber Cable is a factory-terminated, high-density fiber assembly for structured cabling in data centers, enterprise networks, and short-reach high-speed optical links. Using OM4 50/125 μm multimode fiber and multi-fiber MPO connectors, it supports parallel-optics applications such as 40GBASE-SR4 and 100GBASE-SR4 while reducing connector count and installation complexity compared with individually terminated duplex links.

Polarity & Gender Options
Type A, Type B, and Type C polarity configurations are available:
Type A: Straight-through fiber mapping
Type B: Reversed fiber mapping
Type C: Pair-reversed mapping
MPO connectors can be supplied as male (with guide pins) or female (without guide pins). Polarity and gender should be matched to the mating cassettes, modules, transceivers, or trunk assemblies in the target cabling system.
Cable Construction
The assembly uses optical fibers protected by aramid yarn strength members and an application-specific outer jacket. Jacket options include LSZH, PVC, OFNR (Riser), and OFNP (Plenum). OM4 cables are commonly supplied in Erika violet/magenta or other specified colors, with custom jacket colors and identification available for project requirements.
Data Center Applications
OM4 MPO assemblies are suited to high-density data center cabling, server-to-switch links, switch-to-switch interconnects, structured fiber backbones, and network migration projects using parallel multimode optics. OM4 supports up to 150 m for 40GBASE-SR4 and 100GBASE-SR4 under the specified optical system conditions.
Testing & Quality Assurance
Each cable assembly is factory tested before shipment. Quality verification can include:
- Insertion loss and return loss testing
- 3D interferometer inspection of MPO end-face geometry
- Microscopic end-face inspection for contamination and defects
- Fiber continuity and polarity verification
- Final connector, labeling, and packaging inspection
Customization & OEM
OEM/ODM production is available for fiber count, cable length, connector brand/type, gender, polarity, insertion-loss grade, jacket material, jacket color, cable structure, labeling, and packaging. Pulling-eye assemblies can also be specified for installations requiring pre-terminated cables to be pulled through conduit or pathways.
Packaging & Delivery
Each assembly is individually protected with anti-static and moisture-resistant packaging and can be supplied with its factory test report. Standard shipping options include DHL, UPS, FedEx, air freight, and sea freight. Commercial documentation can include commercial invoices, packing lists, and certificates of origin according to destination and order requirements.
FAQ
Q: What connector interfaces can be used with OM4 MPO fiber cables?
A: MPO/MTP connectors can be combined with LC, SC, or other connector interfaces through appropriate breakout or conversion assemblies. The connector combination should be specified according to the equipment ports and the required link architecture.
Q: How should I select the required MPO cable length?
A: Specify the finished cable length based on the actual routing path, including rack-to-rack or rack-to-equipment distance. For structured cabling, allowing sufficient routing slack is recommended to avoid excessive tension or tight bends during installation.
Q: What information should I provide when requesting an MPO cable quotation?
A: A purchase inquiry should normally specify fiber count, cable length, MPO type, connector gender, polarity, connector interface, jacket requirement, insertion-loss grade, quantity, and destination country. Providing the equipment or transceiver model is also useful when compatibility needs to be verified.
Q: Can the MPO cable be supplied with different connector brands?
A: Yes. Connector brands can be specified for projects requiring compatibility with an existing MTP/MPO infrastructure. The mating connector system and keying requirements should be confirmed before production, especially when mixing components from different manufacturers.
Q: Are breakout MPO cables available for equipment connections?
A: Yes. MPO-to-LC and other breakout configurations can be produced when a multi-fiber MPO trunk needs to connect to individual duplex equipment ports. The breakout fiber mapping should be confirmed together with the required polarity before production.
Q: What is the typical lead time for OM4 MPO cable orders?
A: Standard configurations are typically produced within 3–7 working days after order and technical details are confirmed. Larger-volume or highly customized orders may require additional production time, which should be confirmed against the required delivery schedule.
Q: Is a sample order available before bulk purchasing?
A: Yes. Sample quantities can be arranged for projects where the buyer needs to verify connector fit, polarity, fiber mapping, cable dimensions, or optical performance before approving a larger production order. Sample charges and shipping costs are normally quoted separately.
