48-Fiber Trunk Construction
Fiber Grouping
The internal fiber grouping defines how the 48 fibers are organized within the trunk assembly and should match the required MPO port arrangement and cable construction.
Breakout Transition
The breakout section separates the fiber groups toward the MPO connector ends while maintaining the defined fiber sequence through the transition.
MPO End Configuration
End-to-End Mapping
The two MPO ends are configured as a defined channel pair, with fiber positions mapped to the specified polarity so the 48-fiber assembly maintains the required channel relationship from end to end.
Connector Compatibility
MPO/MTP interfaces are manufactured for interoperability with compliant MPO interface hardware in accordance with IEC 61754-7 and TIA-604-5 (FOCIS 5).
End-Face Geometry
After MPO termination and polishing, connector end faces undergo inspection for physical geometry and surface condition. Automated 3D interferometric measurement verifies parameters including radius of curvature, vertex offset, and fiber undercut or protrusion.
Verified Optical Specifications
Fiber-by-Fiber Optical Testing
Each completed 48-fiber assembly undergoes 100% insertion loss (IL) and return loss (RL) testing for every fiber channel before shipment.
Continuity and Polarity Verification
All fiber channels are checked for continuity and verified against the approved polarity and channel mapping before release.
Connector End-Face Inspection
MPO/MTP connector end faces are inspected for contamination, damage and physical conditions that could affect optical contact. End-face geometry is verified by automated 3D interferometric measurement where applicable.
Test Records
Optical and inspection results are retained for the completed assembly and can be supplied with the shipment according to the required documentation format.
Custom Specifications
Connection Configuration
The quotation specification confirms the connector interface, gender, polish and polarity before production.
Fiber Configuration
Fiber type and internal grouping are confirmed against the required optical link before assembly.
Physical Configuration
Cable construction, breakout arrangement, identification and other physical requirements are reviewed before production.
Order Reference
The approved production specification is retained as the reference for repeat orders and configuration-controlled manufacturing.
Quality Control
Specification Review
The approved production specification is reviewed before manufacturing to establish the required fiber configuration, MPO end configuration, polarity, cable construction and inspection requirements.
Controlled Assembly
Cable preparation, fiber grouping, MPO termination and polishing are checked against the approved production specification during assembly.
Process Inspection
Critical assembly stages are inspected before the completed cable proceeds to final verification, including connector termination, breakout construction and identification.
Digital Traceability
Each completed cable assembly is assigned a unique serial number and QR code, which can be used to trace the corresponding optical test and inspection records for the individual assembly.
Final Release
The finished cable is checked against the approved production specification and inspection records before shipment.
FAQ
Q: What is a 48 fiber MPO trunk cable?
A: A 48 fiber MPO trunk cable is a factory-terminated multi-fiber assembly containing 48 optical fibers with MPO/MTP connectors at both ends, providing a pre-terminated connection between compatible multi-fiber interfaces.
Q: How should MPO polarity be specified when ordering a 48 fiber trunk cable?
A: The required polarity should be confirmed against the mating equipment and optical link design before production, because the selected polarity defines the fiber-position relationship between the two MPO ends.
Q: What information should be confirmed before ordering a 48 fiber MPO trunk cable?
A: The purchase specification should define the required fiber and connector configuration, polarity, cable construction, length and testing requirements before production so the finished assembly can be manufactured against one approved reference.
Q: How is MPO connector end-face quality verified?
A: MPO/MTP connector end faces are inspected after termination for physical condition, while 3D interferometric measurement can verify connector geometry such as radius of curvature, vertex offset and fiber undercut or protrusion where required.
Q: Can a 48 fiber MPO trunk cable be produced to a customer-specific configuration?
A: Yes. The production specification can incorporate project-specific connection configuration, fiber grouping, breakout construction, identification and documentation requirements.
Q: Can the same 48 fiber MPO trunk cable configuration be reproduced for repeat orders?
A: Yes. The approved production specification is retained as the reference for repeat orders, allowing the defined assembly configuration to be reproduced consistently between production batches.
Q: Can individual test records be provided for each 48 fiber MPO trunk cable?
A: Yes. Optical and inspection records can be retained against the individual assembly identification and supplied with the shipment when required by the purchasing specification.
Q: How is a finished 48 fiber MPO trunk cable traced after production?
A: Each completed cable assembly is assigned a unique serial number and QR code, which can be used to trace the corresponding optical test and inspection records for the individual assembl
Q: What is the difference between a 48 fiber MPO trunk cable and a 24 fiber MPO trunk cable?
A: A 48-fiber MPO trunk cable provides twice the fiber count of a 24-fiber trunk within the corresponding assembly configuration. The choice depends on the required fiber capacity, trunk architecture, port configuration and channel mapping of the optical link.
