High-speed transceivers, high-density distribution patch panels, and outdoor drop cable accessories supporting 2-core terminations.
Established in 2012 in Hong Kong as a high-tech communications enterprise, Kocent Optec Limited has emerged as one of China's most trusted manufacturers and solution providers for premium fiber optic termination products. Over the past decade, we have dedicated ourselves to research, development, and advanced manufacturing of optical communication equipment, spanning passive components to active network modules.
Our Philosophy: By leveraging our extensive experience and excellent production capacity we gained over the years, we magnify the outcome for our valuable customers, which ultimately expands their core competencies and helps them outperform competitors. We place emphasis on customer collaboration, and we define ourselves as your valuable partner in fiber optic connection solutions.
At Kocent Optec, we build reliable bridges of light. From the backbone of metropolitan Area Networks (MAN) to the delicate final span of Fiber-to-the-Home (FTTH) setups, our cables maintain the structural and optical integrity needed for seamless, ultra-high-speed connectivity.
A 2 Core Fiber Cable (commonly consisting of two distinct optical fibers contained within a protective outer sheath) is the standard structural link for duplex optical data pathways. Our advanced factory production lines support custom modifications across structural geometry, core selection, tensile elements, and outer jacket materials to match target deployment environments.
Typically, a 2-core arrangement is deployed as either a flat-drop cable (Figure-8 or bow-type) for FTTH subscriber lines, or as a duplex patch cord cable for internal datacenter cross-connects. In both scenarios, the choice of raw glass, cushioning layers, and tensile strength elements directly dictates long-term performance.
Through our advanced OEM services, we offer specialized choices for fiber cores: from standard dispersion-unshifted single-mode fiber (G.652.D) to advanced bend-insensitive configurations (G.657.A1 and G.657.A2), allowing networks to negotiate tight micro-bends in compact wall boxes without signal degradation.
Understanding how structural material decisions influence installation efficiency and lifetime physical endurance.
Designed for last-mile residential subscriber drops. Incorporates a high-strength self-supporting steel wire (for aerial span tensile strength) paired with twin FRP (Fiber Reinforced Plastic) members to prevent micro-bend loss and physical crushing.
Optimized for structured cabling and dense patch panel configurations. Outer jacket is easily separated for connector termination (typically LC/SC), using high-tensile aramid yarn (Kevlar) to distribute pull-force during routing.
Encased in a corrugated steel tape or spiral steel armor layer. This layer repels rodents, resists extreme crush pressure, and prevents water infiltration, making it ideal for underground conduits, industrial plants, and utility ducts.

With more than 13 years of experience in manufacturing telecommunication fiber optic products, we strictly follow fiber optic industry standards. We use mature scientific methods to deliver your products on time and ensure that 100% of products are tested and inspected before shipment.
100% Optical Performance Verification: Each batch of OEM 2-core fiber cables undergoes comprehensive optical time-domain reflectometer (OTDR) analysis to ensure zero backscatter anomalies. Connectorized duplex lines undergo three-dimensional geometry testing via laser interferometers, ensuring sub-micron alignment tolerances that yield insertion loss ≤0.2dB and return loss ≥60dB (for APC finishes).
Our global shipping frameworks accommodate custom packaging, drum dimensions, and color identification coding. Whether you require continuous long-run distribution spools of 2000m/roll or specialized pre-connectorized customer premise assemblies, our factory configuration yields optimized procurement margins.
Years of sales and service experience have enabled us to win customers across East Asia, Southeast Asia, Middle East, Europe, Americas, and Africa. Many of our OEM and ODM products have won major Telecom Operator tenders.
Our optical assemblies satisfy rigorous service provider qualifications, ensuring minimal path loss over multi-decade lifespans. We are proud to partner with and supply components to some of the world's most critical telecommunications operators:
The telecommunications industry is moving toward denser networks with smaller carbon footprints. As an OEM pioneer, Kocent Optec is proactively addressing these transitions through three core manufacturing developments:
We are integrating G.657.B3 optical fiber glass preforms, allowing a minimum bend radius down to 5mm. This enables field technicians to route 2-core drop cables around sharp structural corners without causing signal dropouts.
To support global compliance demands (such as the EU Construction Products Regulation - CPR), we manufacture custom LSZH compounds. These materials minimize toxic gas emissions during structural fires while incorporating bio-sourced, eco-friendly polymers.
By using thin-wall extrusion tooling, we have reduced the standard outer diameter of 2-core bow cables by up to 20%. This design fits more cables in narrow ducts, optimizing capacity in crowded urban channels.
