AI-Powered supplier vetting

SummaryHangzhou Softel Optic Co., Ltd. is an established manufacturer focused on CATV, HFC broadband, optical transmission, and related fiber-optic equipment. Evidence indicates five production lines, more than 1,000 square meters of production assembly space, stated quality checks at three stages, six to ten quality-control staff, and output capacity of 2,000 optical transmitters and 5,000,000 meters of fiber-optic cable annually. The company reports strong export activity and has exported since 2006. Its R&D focus and senior technical staff support technical capability, but total R&D engineering experience is stated as three years and no supplier management-system certification is reported. Customization and after-sales capabilities are not specifically documented. Trade records show five transactions in 2025 involving one buyer in the Philippines, providing limited customer-case evidence.

Supplier typeThe supplier presents itself as a manufacturer and R&D-focused producer of CATV, HFC broadband optical transmission equipment, fiber-optic cable, and related products. Its five production lines, stated assembly facility, and product-specific output figures support classification as a manufacturing supplier rather than only a trading intermediary.

CertificationsThe supplier's certification of management systems is explicitly recorded as "NIL." No management-system certification is evidenced in the provided information.

R&D capabilityThe company states that it specializes in R&D of CATV system equipment and identifies strong R&D capability in optical transmission. However, the stated total experience of R&D engineers is three years, and no specific patents, new-product records, or engineering achievements are provided.

Production capacityProduction capability is supported by more than 1,000 square meters of standard production assembly space, five production lines, six to ten quality-control staff, and stated annual capacities of 2,000 optical transmitters and 5,000,000 meters of fiber-optic cable. The supplier also describes material checks, post-production stability and performance testing, and packing checks before delivery.

Client casesTrade records document five 2025 transactions with FIBERNET BROADBAND INC in the Philippines, covering connectors and active equipment. This provides evidence of at least one associated buyer and actual product shipments, but the customer-case record is limited to one named buyer and does not demonstrate a broad customer base.
