DTECH Fiber Optic Patch Cord SC/UPC to SC/UPC, Single Mode 3.0mm Outdoor Jumper, Low Insertion Loss, 1–30m DT-SC/SC 001

A fiber optic patch cord like the DTECH DT-SC/SC 001 connects two SC/UPC ports over single-mode fiber, carrying signal with low insertion loss and high return loss across lengths from 1m up to 30m. It’s built with an LSZH outer jacket rated for outdoor use, aimed at data centre, telecom and structured cabling runs where a clean, stable link matters.

Precision Ferrule Grinding for Low Insertion Loss

DTECH grinds the ferrule end face on a four-corner grinding machine, controlling the centre offset and end-face curvature to tight tolerances. The result, after multiple rounds of testing, is a typical insertion loss of 0.20dB (maximum 0.30dB) and a return loss of 50dB or better — the two numbers that determine how much signal a connector loses and how much it reflects back, both of which matter for link budgets on longer or higher-speed runs.

Speed and Distance

The cord is single-mode, single-core fiber, supporting 1.25G, 10G, 25G and 40G link speeds, and is available in nine lengths from 1m to 30m (1/2/3/5/10/15/20/25/30m) to match the run without unnecessary slack.

LSZH Jacket, Built for Data Centre Safety

The outer jacket is aramid yarn plus low-smoke, zero-halogen (LSZH) material, using flame-retardant raw material rated to IEC 60332-1-2 and GB/T 18380.12-2008. DTECH states the smoke density stays low enough for 86.4% light transmittance during combustion — well inside the IEC 61034-2 requirement — and that the halogen acid gas content meets IEC 60754-1:2011, so it carries no halogen elements. That combination is standard practice for cabling that runs through occupied or enclosed spaces, where smoke and gas output during a fire matter as much as cable performance.

Built to Handle Real-World Installs

The SC connector is rated to 70N of tensile strength (roughly 7kg) with insertion loss changing by no more than 0.3dB over an hour under that load, so a cable that gets pulled or snagged during installation isn’t immediately compromised. The fiber core itself is described as bend-insensitive for easier routing in tight spaces, and each connector ships with a dust cap plus a ceramic ferrule for stable, repeatable connections over repeated plugging and unplugging. See BAM’s industrial serial and cabling range for the rest of the structured cabling accessories it pairs with.

Frequently Asked Questions

What connector type does this fiber optic patch cord use? SC/UPC on both ends.

What insertion loss should I expect? Typically 0.20dB, with a maximum of 0.30dB per DTECH’s testing.

Is it rated for outdoor use? Yes — it’s built with an LSZH-jacketed outdoor-rated design.

What speeds does it support? 1.25G, 10G, 25G and 40G, depending on the transceivers at each end — the cord itself is single-mode fiber, so speed is set by your equipment rather than the cable.
