LC UPC to FC UPC OM3 Multimode Duplex Patch Cable – G657A1 Bend Insensitive, 10mm Min. Bend Radius, 2.0mm LSZH

A: A hybrid jumper removes one mating-pair from the optical path, saving roughly 0.3 dB of insertion loss and one potential dirt-ingress point. On a tight 10G multimode link budget this matters - which is why the LC UPC to FC UPC OM3 hybrid cable is preferred over a daisy-chain of two jumpers plus an LC-FC adapter.

A: Standard G652D fiber loses around 1–2 dB per turn when bent to 10 mm. G657A1 fiber holds that loss below 0.1 dB. In practical terms, the G657A1 LC-FC OM3 2.0mm patch lead can be routed around a corner post or inside a cable finger without measurable signal degradation - something an older fiber construction cannot do.

A: LSZH is the European and international low-smoke-zero-halogen rating (IEC 60332-1 / EN 50575 Cca). It is accepted for general indoor, riser, and cable-tray runs but is NOT equivalent to the North-American OFNP plenum rating. If your project specifically requires OFNP under NEC, request the OFNP-jacketed variant of this LC-FC OM3 duplex jumper.

A: Yes. OM3 50/125 laser-optimized fiber is rated for 10GBASE-SR up to 300 m. Because the ≤0.3 dB insertion loss on this LC-FC 10G multimode cord leaves ample margin at the connector pair, the full 300 m reach is achievable - provided the downstream link is also OM3 or better.

A: OM1 (62.5/125) maxes out at 33 m for 10GBASE-SR; OM2 (50/125) reaches only 82 m at 10G. OM3 extends that to 300 m. For any new 10G-capable install, the 50/125 OM3 LC-FC duplex jumper is the minimum specification that future-proofs the link. If your project may later scale to 40G or 100G, see our detailed OM3 vs OM4 multimode fiber performance comparison to determine whether upgrading to OM4 at installation time is worthwhile.

A: UPC vs APC is a factory-polish choice and cannot be converted in the field. On bulk orders we produce LC APC / FC APC variants as separate SKUs - but note that APC end-faces are green-boot coded and typically used in PON/FTTH singlemode, not OM3 multimode. For 10G multimode links, LC UPC to FC UPC is the correct polish pairing. For a full breakdown of how PC, UPC, and APC end-face geometries differ in return loss performance, refer to our fiber connector polish type guide covering PC vs UPC vs APC specifications.

A: MOQ is 100 pieces per length-SKU for stock configurations. Lead time is 3–5 working days for standard LSZH 2.0 mm aqua assemblies, and 7–12 working days for custom-jacket or custom-length wholesale LC to FC OM3 patch cord batches. Containers of 5,000+ pieces are quoted per project.

A: Use a reel-type fiber cleaner on both ends before every mating. For field inspection, a 200× / 400× video fiber scope verifies the end-face against IEC 61300-3-35 pass/fail criteria. Dust-capping the bend insensitive LC-FC OM3 cable between uses is mandatory - dirt is the single largest cause of link-margin failure on a hybrid assembly.

A: Yes. Every unit is 100% interferometer-measured for apex offset, radius of curvature, and fiber undercut, and insertion-loss / return-loss tested at 1310 nm and 1550 nm. Individual serial-numbered test reports are available on wholesale LC-FC OM3 duplex bulk orders at no additional charge.

A: Custom lengths from 0.5 m up to 300 m are manufactured to order. For bulk orders that mix lengths (0.5 m, 1 m, 2 m, 3 m, 5 m, 10 m, 20 m) on the same PO, the LC UPC to FC UPC OM3 duplex patch cable supplier can consolidate all cuts into one shipment to reduce freight.

A: No. The 2.0 mm LSZH tight-buffered construction is designed for indoor / in-building applications. For outdoor direct-burial runs you need an armoured or gel-filled outdoor cable terminated onto an ODF, and this indoor jumper plugged into the ODF patch side.

A: Operating temperature is −20 °C to +70 °C, storage −40 °C to +80 °C. That covers indoor data-centre, telecom-room, and conditioned broadcast environments. For colder unheated outdoor shelters, specify the industrial-temp variant instead of this LC-FC OM3 LSZH patch cable.
