Questions on Custom Fiber Assemblies
The topics our application engineers answer most often. If your question is not here, write to us — a real engineer reads every inquiry.
Products & Customization
Yes. Any combination of LC, SC, FC, ST, MPO/MTP, SMA and HFBR/Versatile Link can be terminated on a single assembly — including mixed SMF and MMF legs on a multi-leg harness.
In most cases, yes. Send the part number or a sample and we will match the fiber, optics, lead form and connector interface for a drop-in replacement.
Yes. We build corrugated-steel armored cables, IP67-sealed assemblies with IP-rated connectors, and outdoor PE-jacketed builds rated for −40 °C to +85 °C.
Single-mode (OS2), multi-mode (OM3/OM4/OM5), plastic optical fiber (POF, 980 μm) and hard-clad silica (HCS). The right choice depends on your reach, data rate and environment.
Ordering, Samples & Lead Time
Sample quantities (≤ 20 pcs of an existing build) usually ship within 5 business days. Custom production runs typically take 2–3 weeks after specification sign-off.
No strict MOQ for custom builds — we regularly ship single-piece prototypes. Per-unit pricing improves with volume, which we will quote alongside the build.
Yes, and we recommend it. A first article lets you verify fit, optical performance and mechanical routing before committing to a production batch.
Yes — for repeat builds we support scheduled-call-off agreements and buffer stock so lead time collapses to days rather than weeks.
Quality, Testing & Documentation
Yes. 100% of assemblies receive insertion-loss and return-loss measurement on calibrated sources and meters. No assembly ships without a passing test result.
Yes. Every connector end-face is inspected under fiber microscopy for scratches, pits, epoxy rings and contamination, per Telcordia GR-326 practice.
End-to-end polarity and continuity are verified on every trunk, with method (A/B/C) documented on the build record — critical for clean 40/100/400G bring-up.
Yes. Individual IL/RL test reports, material declarations (RoHS/REACH) and certificates of conformance are available on request.
Shipping, Regions & Support
We ship globally. Lead times to your door depend on the destination and chosen carrier; we will quote freight alongside the build.
Each assembly is individually coiled, labeled with part number and serial, then packed in protective containers suited to the connector type and shipping mode.
Yes. The same application engineer who scoped your build supports it after delivery — including field issues, revisions and reorder reproduction.
Yes. We routinely sign mutual NDAs before discussing custom specifications, drawings or end-customer details.
