Shanghai Sun Telecommunication Co., Ltd.

Shanghai Sun Telecommunication Co., Ltd. is based in Shanghai, China and lists five active products. The catalogue covers Ethernet fiber optic media converters, a single‑fiber fusion splicer (SUN‑FS930), a 155 m 1.25 Gbps SFP transceiver, a handheld OTDR model (SUN‑OT5000) and general outdoor fiber optic cables. All items fall under the broader categories of Telecommunication Infrastructure/Equipments, Electronic Terminals and Optical Fiber Cables as indicated in the supplier data. The product list does not include HS codes, so classification must be derived from standard tariff headings for similar goods. The company is classified as an imported supplier with a harbor trust tier, indicating a moderate level of verification by the platform.

The supplier’s five listed items address core segments of fiber‑optic network deployment. Media converters enable Ethernet links over fiber, while the SFP transceiver provides 1.25 Gbps optical interfaces compatible with IEEE 802.3. The handheld OTDR supports field testing of fiber loss and fault location, and the fusion splicer is used for permanent single‑fiber joints. General outdoor fiber optic cables are typically jacketed for burial or aerial use. These products collectively support the installation and maintenance of broadband and carrier‑grade networks.

The catalogue includes Ethernet fiber optic media converters that comply with IEEE 802.3 standards, typically supporting 10/100/1000 Mbps rates and using LC or SC connectors. In the optical fiber market, single‑mode cables are graded to ITU‑T G.652 or G.657 specifications and often supplied in 100 m or 1 km reels; multimode variants follow IEC 60793‑2 standards. The 155 m 1.25 Gbps SFP transceiver is usually classified under SFF‑8472 with a typical wavelength of 1310 nm and a maximum power output of - 3 dBm. Handheld OTDRs such as the SUN‑OT5000 normally offer a measurement range up to 20 km, dual‑wavelength operation (1310 nm/1550 nm), and a dynamic range of 30 dB. Single‑fiber fusion splicers are rated for splice loss ≤0.1 dB, core alignment accuracy of ≤0.5 µm, and often include a built‑in visual fault locator. Outdoor fiber optic cables listed are generally armored or water‑blocking variants designed for underground or aerial deployment, with typical outer diameters of 6 - 12 mm.
