Fujikura 1886-455368-11 RF Coaxial Cable Assembly – Obsolete Telecom Spare Part

When a single cable assembly failure forces a full platform migration, the cost is rarely measured in cable prices alone. Engineering re-qualification, new rack infrastructure, software re-licensing, and production downtime can push a single forced upgrade well past seven figures. The Fujikura 1886-455368-11 — a 52-foot RF coaxial cable assembly cross-referenced under part numbers 716-140139-313, 156403, and 17E181W412G1 — is no longer in active production. For facilities still operating legacy telecom, wireless backhaul, or RF distribution systems built around Fujikura-specified cabling, this assembly is a direct-fit replacement that eliminates the engineering overhead of a forced redesign.

DriveKNMS maintains verified physical stock of this assembly. Procurement teams and plant engineers who have spent months chasing this part through distribution channels will find no substitutes here — only the original-specification component.

Technical Specifications

Note: Electrical parameters such as impedance, frequency range, and connector type are confirmed only against physical inspection of each unit. No parameters are published here that have not been verified. Contact us for a full test report on available stock.

Solving the Discontinued Hardware Crisis

RF coaxial cable assemblies of this specification were designed into telecom base station infrastructure, wireless backhaul nodes, and RF signal distribution frames during a period when Fujikura held significant market share in precision cable assembly. Systems built to these specifications — particularly those referencing the 2800 and 3000 series platform interfaces — were engineered for 15–20 year operational lifespans. The problem is that the cable assemblies themselves, subject to mechanical stress, connector wear, and environmental degradation, fail well before the host system reaches end-of-life.

When the 1886-455368-11 is no longer available through standard channels, the decision facing plant management is binary: locate the original-specification part, or commit to a platform migration that touches every layer of the RF architecture. Migration projects of this scope routinely require 12–24 months of engineering time, carry significant risk of signal performance regression, and demand capital expenditure that was not budgeted. The math is straightforward. A verified spare assembly, even at a premium price, costs a fraction of what a forced migration demands.

Facilities that have extended the operational life of legacy RF infrastructure by 5–10 years beyond OEM support windows consistently cite the same strategy: maintain a minimum buffer stock of critical cable assemblies and connectorized components. A single spare of the 1886-455368-11 held in climate-controlled storage represents insurance against a failure event that would otherwise trigger an unplanned capital project. For multi-site operators, a centralized spare pool covering two to three units per platform type has proven sufficient to absorb field failures without triggering emergency procurement at distressed pricing.

Condition & Reliability Assurance

Every unit of the 1886-455368-11 processed through DriveKNMS undergoes a structured 5-step inspection protocol before it is offered for sale:

• Step 1 – Visual and Mechanical Inspection: Full-length cable jacket examination for cracking, kinking, or crush damage. Connector body inspection for corrosion, thread damage, and seating integrity.
• Step 2 – Pin and Contact Corrosion Assessment: Center conductor and outer contact surfaces are examined under magnification. Units showing oxidation beyond acceptable limits are rejected or remediated before testing.
• Step 3 – Connector Continuity and Isolation Test: Each assembly is tested for center conductor continuity and shield-to-conductor isolation to confirm the assembly has not developed internal opens or shorts.
• Step 4 – Firmware and Label Verification (where applicable): Part number markings, date codes, and any embedded identification are cross-checked against procurement documentation to confirm part identity.
• Step 5 – Packaging and Storage Certification: Units are repackaged in anti-static, moisture-barrier packaging with desiccant and stored in a controlled environment prior to shipment.

Condition grade and test results are documented and provided with each shipment on request.

Key Features for System Maintenance

• Drop-in replacement: The 1886-455368-11 installs directly into the original mounting position without modification to the host system. No re-routing, no adapter hardware, no signal path redesign.
• No reprogramming required: RF cable assemblies carry no firmware or configuration state. Replacement restores signal path performance without any software intervention.
• Avoids engineering reconstruction costs: Using the original-specification assembly eliminates the need to re-qualify signal performance, re-certify the RF chain, or update system documentation — all of which add cost and delay to any alternative approach.
• Preserves system certification: In regulated environments, substituting a non-original cable assembly may invalidate existing type approvals or site certifications. The 1886-455368-11 maintains the original-specification signal path.
• Long-term asset protection: Maintaining a buffer stock of this assembly is a documented low-cost strategy for extending the operational life of legacy RF platforms by 5–10 years beyond OEM support windows.

FAQ

What warranty applies to obsolete parts?
DriveKNMS provides a 90-day warranty against defects in materials and workmanship on all tested units. New Old Stock (NOS) units carry a 30-day inspection warranty. Warranty terms are confirmed in writing at the time of order.

How do I confirm the unit is genuine and not a counterfeit?
Each unit is inspected against original Fujikura part markings and documentation. We provide a condition report and, where available, original packaging or manufacturer labeling. We do not sell units that cannot be positively identified against the original part number.

Should I purchase more than one unit?
For any system where this assembly is a single point of failure, holding a minimum of one spare unit on-site is the standard recommendation. For multi-site operations or systems with multiple RF paths using this assembly, a buffer of two to three units is a defensible procurement position. The cost of a second unit is negligible relative to the cost of an unplanned outage while emergency procurement is underway.

Can you source additional quantity if I need more than you have in stock?
DriveKNMS maintains active sourcing relationships for obsolete Fujikura cable assemblies. Contact us with your quantity requirement and timeline. We will confirm availability before any commitment is made.
