Ningbo Weelink Telecom Co., Ltd.

Ningbo, China hosts Ningbo Weelink Telecom Co., Ltd., which currently lists 21 active products across its catalogue. The company’s listings span categories such as Wine Bottle Racks, Tools & Instruments, Electric Connectors, Optical Fiber Cables, Electric Conductors, Industrial Couplings, Electronic Testers, and Wires & Cables. Among the 21 items are fiber optic components like FTTH Fiber Optic Fc Lc Sc Apc Fast Connector (HS 8536.70) and Low loss Fiber Optic ST Adapter (HS 8544.70), as well as network infrastructure equipment such as a 12U rack cabinet and a 19‑inch vented network cabinet (HS 9403.20). The catalogue also includes Ethernet accessories like cat5e/cat6 UTP or STP inline couplers, RJ45 LAN network cable testers, and various crimping and insertion tools. Each product entry references its material composition where provided, for example ceramic ferrules and phosphor‑bronze sleeves for the fiber connectors.

The product set reflects typical telecom‑grade hardware used in FTTH deployments, data centre racks, and field testing. HS code families represented include 85‑36 for fiber optic connectors, 85‑44 for fiber adapters, and 94‑03 for steel network cabinets, aligning with international tariff classifications for telecom equipment and metal enclosures. The supplier’s catalogue also lists items without explicit HS codes, such as a 24‑core MPO fiber optic patch cord and a wall‑mounted 6U network cabinet, which would generally fall under HS 85‑xx or 94‑xx depending on material. Overall, the 21‑item range provides a snapshot of components that support optical networking, Ethernet cabling, and rack‑mount infrastructure.

The listed catalogue includes FTTH fiber optic FC/LC/SC APC connectors, low‑loss ST adapters, LC‑LC duplex multimode couplers, and a 24‑core MPO patch cord. In the telecom industry these components are typically manufactured to IEC 61754‑1 (for FC/LC/SC) and IEC 61754‑2 (for ST), with insertion loss ≤0.3 dB and return loss ≥55 dB for single‑mode parts. Ceramic ferrules (zirconia) and phosphor‑bronze sleeves are standard materials that provide high precision and durability. Ethernet accessories such as cat5e and cat6 UTP/STP inline couplers and RJ45 LAN testers are generally designed to meet TIA‑568‑C and IEC 61156 standards, supporting up to 1 Gbps for Cat5e and 10 Gbps for Cat6 over 100 m runs.

Network cabinets in the catalogue - 12U rack cabinet, 19‑inch double‑open mesh door server rack, vented 19‑inch cabinet, and tempered glass 4U wall‑mounted unit - are built from cold‑rolled steel (SPCC) with powder coating, matching the EN 50155 and IEC 60297 rack specifications. Typical dimensions follow the 19‑inch rack standard (width 482 mm, depth 600‑800 mm) and provide a load capacity of 500 kg for steel frames. Crimping tools, KRONE LSA‑PLUS insertion tools, and mini insertion tools cater to field termination of RJ45 and fiber connectors, where ergonomic design and calibrated torque (≈5 Nm) are industry expectations.
