About Wuhan Optotop Co., Ltd. - Optical Fiber & Magnetic Products Supplier in China

Wuhan, China is the base for Wuhan Optotop Co., Ltd., which currently lists ten active products. The catalogue spans optical fiber cable accessories such as splitters, wavelength‑division multiplexers, MPO patch cords, OSFP‑SR8 jumpers, ODF terminal boxes, attenuators and breakout modules, as well as a magnetic composite sleeve that carries HS code 8544.70. Each entry reflects a distinct product family within the broader categories of Optical Fiber Cables, Electric Switches & Isolators, and Magnets & Magnetic Products. The supplier’s HS‑code exposure therefore includes the 8544 series for magnetic components and the 8544‑10/12 series typically used for fiber optic assemblies.

The listed products use industry‑standard connector types (SC/APC, LC, MPO) and wavelength ranges (980 nm, 1510 nm) that align with ITU‑T G.655 and G.652 specifications. Attenuators are described with a 1‑50 dB range and high return loss, indicating compliance with IEC 60793‑1‑1 for insertion loss and return loss limits. The magnetic fiber sleeves combine ferrite magnet material with reinforced polymer, a composition often classified under HS 8544.70 for magnetic components. No additional certifications are claimed in the supplied data.

Product Range and Specialties of Wuhan Optotop Co., Ltd.

The catalogue’s optical fiber items cover single‑mode splitters (1x3 EVEN), dual‑channel WDM modules (1 × 2 980 nm/1510 nm), low‑loss MPO patch cords (8/12/24/48F), OSFP‑SR8 or MPO jumpers, rack‑mounted ODF terminal boxes, high‑return‑loss attenuators (1‑50 dB), MPO‑to‑LC breakout assemblies, and a mini pigtail. In the industry, such components are typically graded to IEC 61754‑2 for fiber type, with insertion loss under 0.3 dB per connector and return loss better than - 55 dB for APC terminations. MPO patch cords are often supplied in 3 mm or 12 mm ferrule formats, with bend radii of 30 mm or greater and jacket ratings of LSZH for fire safety.

The magnetic product is a patented 45 mm fiber sleeve made from a ferrite‑magnet core encapsulated in reinforced polymer, classified under HS 8544.70. Similar magnetic composites are used for EMI shielding and are evaluated for permeability (µr ≈ 200‑500) and shielding effectiveness (≥ 30 dB at 1 GHz). Buyers normally request material data sheets, magnetic loss measurements, and compliance with IEC 60721‑3‑3 for environmental conditions.

Trade and Export Information - Wuhan Optotop Co., Ltd.

China is a global exporter of optical fiber components and magnetic assemblies, with the majority of shipments routed to Europe, North America and fast‑growing Asian markets such as South Korea and Japan. The HS‑code family 8544 covers both fiber optic cables (8544‑10/12) and magnetic components (8544‑70), and customs authorities commonly require certificates of conformity to IEC standards, as well as RoHS and REACH declarations for electronic and magnetic goods.

Typical importers request test reports confirming insertion loss, return loss, wavelength accuracy for WDM modules, and magnetic permeability data for composite sleeves. While Wuhan Optotop does not list specific certifications, buyers should verify ISO 9001 quality‑management certification, CE marking for EU markets, and any applicable IEC type‑approval for fiber optic connectors. Logistics for these items usually involve 20‑ft or 40‑ft containers with anti‑static packaging for fiber optics and metal‑ized protective cases for magnetic sleeves, using Incoterms such as FOB or CIF.

Sourcing from Wuhan Optotop Co., Ltd. - Buyer Guidance

When sourcing optical fiber accessories from this supplier, request detailed technical datasheets that list insertion loss (≤ 0.3 dB), return loss (≥  - 55 dB for APC), wavelength tolerance (± 5 nm for WDM), and mechanical specifications such as bend radius and jacket material. For the magnetic sleeve, obtain material safety data sheets, magnetic permeability values, and test reports demonstrating compliance with IEC 60721‑3‑3 or equivalent EMI‑shielding standards.

Buyers should also ask for third‑party test certificates (e.g., UL, SGS) and confirm whether the supplier holds ISO 9001 or CE certification, even though these are not listed in the provided facts. Verify packaging details - fiber components are normally shipped in anti‑static bags with moisture‑absorbing desiccants, while magnetic products require sturdy cartons with metal‑shielding inserts - before finalizing the order.

What HS code is used for the magnetic fiber sleeves?

The magnetic fiber sleeves are classified under HS code 8544.70, which covers magnetic components made of composite materials.

Which connector types are available in the optical splitter range?

The catalogue lists a 1x3 EVEN splitter with an SC/APC connector, conforming to IEC 60793‑1‑1 specifications for APC terminations.

What wavelength bands does the WDM module support?

The MU/UPC Fiber Optic WDM module operates on 980 nm and 1510 nm channels, a typical dual‑band configuration used in metro‑range fiber networks.

What performance parameters are specified for the fiber attenuators?

Attenuators are described with a 1‑50 dB attenuation range and high return loss, indicating insertion loss accuracy and return loss better than - 55 dB.

Are there any standard certifications buyers should request for these products?

Buyers usually request ISO 9001 quality‑management certification, CE marking for EU shipments, and RoHS compliance for electronic components; specific certifications are not listed for this supplier.

What packaging is typical for the MPO patch cords?

MPO patch cords are generally packed in anti‑static, moisture‑controlled bags within reinforced cartons, to protect the 8/12/24/48‑fiber configurations during transit.

What are the common export markets for Chinese optical fiber accessories?

Major import destinations include the United States, Germany, the United Kingdom, Japan and South Korea, where telecom operators and data‑center builders source such components.

What documentation should be verified before ordering the magnetic sleeve?

Request a material safety data sheet, magnetic permeability test report, and any IEC or UL conformity certificates to confirm the sleeve meets EMI‑shielding requirements.
