Jera is a professional integrated manufacturer with independent core technology for full-process fiber optic cable research, development, production and fabrication, focusing on customized and standardized fiber optic cable solutions tailored for overhead aerial laying, underground buried piping and whole-scenario communication infrastructure construction worldwide. Rooted in the optical communication connectivity industry for years, the company has built standardized closed-loop production workshops, complete industrial manufacturing chains and mature supply chain management systems, fully supporting bulk order mass production, small-batch customized manufacturing and special engineering model development for global telecom operators, engineering contractors, system integrators and distribution traders.

Equipped with multiple full-automatic dedicated fiber optic cable production lines, Jera covers mainstream indoor and outdoor drop cable models widely applied in global FTTX access network projects, including classic hot-selling specifications: GJXH, GJXFH, GJYXCH, GJYXFCH and other self-supporting aerial fiber drop cables. All core molding, stranding, extrusion and testing production equipment are imported from globally renowned industrial manufacturing brands with stable operational performance and ultra-high processing precision. Compared with ordinary domestic processing machinery, international-grade production equipment effectively controls cable outer diameter tolerance, fiber core excess length, structural concentricity and overall mechanical stability in every production procedure, eliminating defective products caused by processing deviation, and laying a solid hardware foundation for consistent high finished product quality and dimensional precision of all Jera optical cables.

Focusing on the global FTTX full-scenario communication market demand, Jera’s professional optical fiber workshop classifies all finished communication optical cables into two major application categories based on actual on-site laying environment, covering the whole lifecycle access demands of user end communication networking. The first category is outdoor aerial dedicated optical cables, independently optimized for overhead pole-mounted laying, cross-airspan wiring, outdoor wall-mounted routing and outdoor open-air erection scenarios. This series of cables is optimized for wind resistance, tensile load, outdoor ultraviolet erosion and temperature alternation, adapted to urban community aerial networking, rural trunk communication wiring, roadside pole communication deployment and outdoor short-distance signal transmission projects. The second category is indoor dedicated wiring optical cables, designed for building weak current wells, indoor ceiling wiring, household wall embedded wiring, machine room internal jumper connection and indoor fire-rated closed wiring environments, featuring small outer diameter, flexible bending performance, low smoke characteristics and easy stripping construction to fit compact indoor wiring space.

Jera implements full-link standardized quality management covering raw material incoming inspection, workshop production process supervision, semi-finished product spot check and finished product factory inspection, strictly abiding by ISO 9001:2015 global quality management system specifications and EU CE market access standards for all raw material screening and acceptance work. Every batch of optical fiber core, reinforcing structural parts and outer sheath polymer materials will pass multi-index sampling inspection before warehousing to cut off quality risks from the source. For core optical conductive units, Jera adopts internationally mainstream telecom-grade fiber cores including G657A1, G657A2 and G.652.D types, which feature low transmission loss, anti-bending fatigue performance and stable optical signal reflection performance, matching long-distance stable transmission and frequent bending indoor wiring demands. In terms of cable structural reinforcement, high-toughness FRP non-metallic reinforcing pieces and high-strength galvanized steel wire are optional strength members for different cable models, improving axial tensile resistance and lateral compression resistance of finished cables to avoid fiber core fracture during laying and use. For outer protective sheath materials, we adopt weather-resistant, anti-ultraviolet optimized LSZH low-smoke zero-halogen material and high wear-resistant TPU polymer material selectively: LSZH sheath meets indoor fire prevention and low-toxic smoke emission construction requirements, while modified TPU sheath adapts outdoor long-term sun exposure, rain corrosion and complex geological outdoor laying conditions.

All finished fiber optic cables manufactured by Jera have passed authoritative third-party certification and testing, complying with mainstream regional industry access standards worldwide, including SGS comprehensive performance certification, IEC international electrical commission unified communication industry standards, and EU CPR construction product safety regulation standards, supporting smooth customs clearance and engineering bidding in European, Southeast Asian, Middle Eastern, African and American regional markets. To realize independent quality control and shorten third-party testing cycle, Jera builds a standardized in-house independent physical and optical performance laboratory equipped with full set professional testing instruments. The laboratory can complete routine and special performance tests independently without outsourcing, including high-low temperature alternating humidity and heat cycling endurance test to verify cable structural stability under extreme climate, standardized flame retardant and fire resistance test to verify fire safety performance of sheath materials, optical fiber core reflection attenuation test, tensile mechanical load test, lateral static pressure resistance test, sheath aging resistance test and bending cycle durability test. Full independent in-lab testing ensures every batch of goods reaches unified qualified standard, and supports customized performance testing for special engineering order demands.

Different from fixed-model mass manufacturers, Jera insists on market-oriented product iteration and flexible customized service mechanism to enhance global market core competitiveness. Our professional optical R&D team can develop brand-new structural optical cables, special environment anti-corrosion optical cables, high-fireproof customized drop cables according to customers’ special laying environment, regional standard requirements and project parameter demands; meanwhile, we can modify structural size, sheath color, tensile strength, fiber core quantity and packaging specifications of existing conventional cable products to match personalized project construction needs. Based on stable self-production capacity and self-inspection quality system, Jera can provide customers with cost-effective quotation schemes, stable batch delivery cycle and traceable after-sales technical support, balancing product high quality and customer procurement cost control.

In terms of long-term factory operation optimization, Jera keeps upgrading workshop intelligent production facilities, steadily promoting production automation transformation and lean production management. The company formulates sustainable cost-efficient production policies, optimizing material utilization rate, reducing manual operation error, lowering comprehensive production energy consumption and logistics loss on the premise of never downgrading raw material grade and product performance. Through automated stranding equipment, intelligent online quality monitoring system and unified warehouse material management system, we improve production efficiency, shorten order delivery cycle and stabilize product quality consistency. Adhering to quality priority, customized service and win-win cooperation business philosophy, Jera welcomes global distributors, engineering contractors and telecom enterprise buyers to contact our business team for detailed product parameter catalog, factory audit arrangement, sample application and tailored bulk order quotation.
