OS2 Single-Mode Fiber Construction
Fiber Construction: DIMI specifies G.652.D, G.657.A1, and G.657.A2 single-mode fiber constructions within the OS2 product range, allowing the fiber design to be matched to the required cable routing conditions.
Bend Performance: G.657 fiber constructions define additional bend-performance characteristics compared with conventional G.652.D fiber, which can be relevant where the planned cable route imposes tighter bending conditions.
Fiber Selection: The specified fiber grade is established as part of the trunk configuration before assembly, keeping the optical construction defined at the product level rather than left as an unspecified fiber option.
Optical Specification of the OS2 Assembly
Finished-Assembly Performance: Optical performance is evaluated on the completed terminated trunk, giving buyers a reference for the cable as supplied rather than for fiber before connectorization.
Insertion and Return Loss: Insertion loss and return loss provide separate optical performance references for the completed MPO assembly, covering transmission loss and reflected optical power.
Pre-Shipment Verification: The finished assembly can be evaluated against the specified optical requirements before shipment, providing test information for quality records and incoming inspection.
Multi-Fiber MPO Trunk Assembly
Consolidated Fiber Structure: Multiple optical paths are organized within a common trunk body and terminated at MPO interfaces, forming one factory-assembled multi-fiber connection.
Controlled Connector Transition: Breakout sections provide a defined transition between the main trunk body and MPO connector branches, keeping the transition geometry controlled during assembly.
Staggered Fan-Out: Where specified, staggered fan-out separates connector transitions along the trunk to accommodate the physical layout of the completed assembly.
Installation Handling: A pulling eye can be incorporated as a designated handling point, keeping installation pulling forces away from the MPO connector interface.
MPO Termination and Verification
Multi-Fiber Ferrule
MPO termination positions multiple optical fibers within a common ferrule, making fiber-end positioning part of the completed connector assembly.
3D Geometry Inspection
DIMI uses interferometric inspection to evaluate MPO ferrule geometry, including radius of curvature, fiber height, and apex offset after termination.
End-Face Inspection
The connector end face is inspected for visible conditions such as contamination and scratches before the assembly is released.
Polarity Verification
Fiber-position correspondence is verified through the completed trunk to confirm the specified polarity configuration.
Assembly Identification
Individual Cable Reference: Each finished assembly can be assigned a serial number associated with its production and inspection information.
Physical Identification: Barcode labels, laser marking, and heat-shrink labels can be incorporated where individual cables need to remain identifiable after delivery.
Order Traceability: Cable identification provides a physical reference for matching delivered assemblies with the corresponding order or inspection records during receiving and subsequent handling.
FAQ
Q: What is the MOQ for OS2 MPO Trunk Cable?
A: The standard MOQ is 500 pieces per style. The final quantity is confirmed according to the order requirements.
Q: Can I order a sample before placing a bulk order?
A: Yes. Samples can be produced before bulk production for buyer evaluation.
Q: How long does sample production take?
A: Sample production typically takes 3–7 working days, depending on the requested configuration.
Q: What is the typical bulk production lead time?
A: Standard bulk production typically takes 15–45 days after order confirmation and completion of the required pre-production process.
Q: What information should I provide when requesting an OS2 MPO trunk cable quotation?
A: Provide the required fiber count, connector configuration, polarity, fiber grade, cable length, jacket requirement, and any identification or packaging requirements. DIMI can then confirm the applicable production specification and quotation.
Q: Can the OS2 MPO trunk cable be configured for a specific fiber count and polarity?
A: Yes. The fiber count and polarity can be specified as part of the cable configuration, subject to the required MPO assembly specification.
Q: Can DIMI coordinate production with a required project delivery schedule?
A: Production scheduling can be discussed according to the confirmed order quantity, production requirements, and requested delivery date.
Q: Can DIMI provide packaging according to shipment requirements?
A: Yes. Packaging requirements can be confirmed according to the order quantity, cable configuration, and shipment requirements.
