OM3 Fiber Characteristics
The OM3 fiber grade defines the multimode transmission characteristics of the optical path, while the MPO/MTP termination determines how the individual fiber channels are presented at the equipment interface.
Assembly-Level Performance
For an OM3 MPO assembly, the fiber specification and connector termination are evaluated as a finished optical path rather than as independent component descriptions.
Loss Configuration
DIMI provides different MPO/MTP loss grades, allowing the finished assembly to be specified according to the optical-loss requirements of the connected link.
Transmission Conditions
The achievable transmission distance depends on the complete optical link, including the transceivers, passive components, and available optical budget, rather than the cable specification in isolation.
Cable Construction
Cable Structure
The selected cable construction defines the internal arrangement and mechanical protection of the multi-fiber assembly before MPO/MTP termination.
Fiber Protection
The selected construction groups and protects the individual fibers according to the specified cable design and fiber count.
Jacket Specification
The jacket construction is defined together with the required mechanical, environmental, and compliance requirements of the finished cable.
MPO Termination
Connector Configuration: MPO/MTP connectors are factory terminated according to the specified connector type, gender, pin configuration, and end-to-end fiber mapping.
Polarity & Fiber Mapping: The specified polarity defines the fiber-position relationship between the two connector ends, with the completed assembly verified against the confirmed mapping before shipment.
Product Quality Verification
Optical Testing
Each finished assembly undergoes insertion loss and return loss testing before shipment according to the confirmed optical specification.
01
Connector Geometry
MPO connector geometry is verified by 3D interferometer measurement, including fiber height, radius of curvature, and apex offset.
02
End-Face Inspection
Connector end faces are inspected for surface defects and contamination before the finished assembly is released.
03
Polarity Verification
Fiber continuity and polarity are checked against the specified mapping to verify channel correspondence across the assembly.
04
Product Traceability
Where serialized reporting is specified, the finished cable can be linked to its recorded optical and connector inspection data through its assigned identification number.

FAQ
Q: Can OM3 MPO cable be used in a link containing OM4 fiber?
A: Mixed OM3/OM4 links should be evaluated against the transceiver specification and system optical budget before deployment, as overall performance depends on the combined fiber and component specifications.
Q: What should be confirmed before placing a repeat OM3 MPO cable order?
A: The approved product specification, previous order reference, or production sample should be used to confirm the agreed configuration before repeat production.
Q: Can an approved sample be used as a production reference for an OM3 MPO cable order?
A: Yes. An approved sample can serve as a production reference when its configuration and applicable inspection requirements are documented in the confirmed order specification.
Q: Can DIMI manufacture an OM3 MPO cable from an existing customer specification?
A: Yes. An existing customer specification can be used as the production reference when the required configuration, technical requirements, and inspection criteria are clearly defined and confirmed before production.
Q: What is normally required for an OM3 MPO cable quotation?
A: Project quantity, target delivery date, existing part number, approved sample, or previous order reference can help the supplier prepare a quotation against the required configuration.
Q: Can OM3 MPO cables be supplied for OEM or private-label orders?
A: OEM or private-label requirements can be incorporated into the confirmed production specification, including agreed product identification, labeling, packaging, and documentation requirements.
Q: What documents can be requested for an OM3 MPO cable order?
A: Buyers can specify required test reports, product identification records, inspection records, or other quality documentation as part of the order documentation requirements.
Q: How can buyers evaluate an OM3 MPO cable supplier before placing a production order?
A: Buyers can review the supplier's product specifications, sample approval process, optical testing records, connector inspection capability, applicable certifications, and production documentation before approving a production order.
