KEY FEATURES & PERFORMANCE
Bend-Insensitive OM3 Core (7.5mm Radius): Ultrasmall 7.5mm minimum
bend radius ensures reliable 10GbE transmission even in high-density or tight-space cabling layouts.
Standard A-to-B Polarity: Configured in standard crossover duplex mode
(Tx to Rx) for instant plug-andplay network connectivity.
Robust Metallic Connectors: Premium FC & ST metallic twist-lock/bayonet
connectors deliver excellent mechanical stability and high insertion durability up to 1000 cycles.
OFNR Riser Rated Aqua Jacket: Non-conductive riser PVC outer jacket meets
building fire safety requirements for vertical riser installations.
This duplex assembly joins a 2.0 mm FC/UPC connector to a legacy ST/UPC bayonet connector over OM3 50/125 µm multimode fibre. It is the cord used when newer FC-patched equipment has to be connected into an existing ST-based fibre panel, which is common in industrial control rooms, older campus backbones and test benches that were cabled before SC and LC became standard.
Two OM3 multimode fibres run side by side in a zip-cord construction with a 2.0 mm or 3.0 mm flame-retardant jacket, allowing the two legs to be separated for individual routing at the panel. The FC end uses a threaded 2.5 mm ferrule with a keyed anti-rotation body, while the ST end uses a 2.5 mm spring-loaded bayonet ferrule. Both ends are polished to UPC and inspected before packing.
Check the panel side first: ST panels are being phased out, so if the legacy equipment is also due for replacement, specifying a duplex LC or SC assembly now avoids buying ST cords twice. Where the cord runs in a high-vibration environment, the threaded FC body is the more secure of the two connectors and should be fitted at the equipment end. Confirm the polish on the legacy panel — mixing UPC cords into an APC panel produces a high loss and a damaged end-face.
Can you supply this assembly in custom lengths and colours? Yes. Huifiber builds patch cords to order in any length from 0.5 m to 50 m, with a choice of jacket colour, boot type and printing. Send us the connector pair, fiber type and length and we will confirm the price within 48 hours.
Do you provide test reports? Yes. Every batch ships with insertion loss and return loss test data, and we can supply an interferometric end-face report for single-mode assemblies on request.
What is the minimum order quantity? Standard configurations ship from 100 pieces. Mixed-model orders can be combined to reach the MOQ.

Buy high-quality FC/UPC to ST/UPC Duplex OM3 Multimode Fiber Patch Cords (50/125μm) from Huifiber. Features low insertion loss & bend-insensitive design.
Yes. Huifiber supplies cable under the buyer's own brand as well as under the Huifiber brand. Fibre count, jacket material, jacket print, drum marking, drum length, packaging and datasheet layout can all be produced to the customer's requirement, and the engineering team can work from a customer specification or adapt an existing construction to a new route requirement.
Every production batch is tested before it leaves the plant in Dongguan. Attenuation and geometry are measured on OTDR and optical bench equipment, and mechanical performance is verified against the datasheet for the construction. A factory test report is issued with each shipment, so an incoming inspection can be checked against the same numbers.
Send the fibre count and fibre type, the jacket material or fire rating, the route length or span and the drum length you need, the destination port or country, and any certification or test-report requirement. With those details the sales engineer can confirm the construction and return a quotation with an indicative lead time.
