About Shenzhen Topstar Technology Industrial Co., Ltd.
Shenzhen Topstar Technology Industrial Co., Ltd. is the registered company name used across this site, taken from the store registration. The shorter form Shenzhen Topstar Technology Co., Ltd. that appears in some source tables is a condensed abbreviation of the registered name: it does not appear word for word on the company website, and it is not used as the company name anywhere on this site. This first section states the naming position plainly so that a buyer comparing documents is not misled by the two forms.
Identity note: the store record for this business lists its Business Type as Trading Company, and this site therefore describes the business as a supplier. The company website also carries manufacturing wording about its own research team and production lines; that wording is quoted here only as a company-website statement, and it conflicts with the Trading Company record. The two positions have not been reconciled, and buyers who need a manufacturing statement for a specific order should ask for it in writing in the enquiry.
Company name and brand
The company website currently presents itself under the name TOPSTAR TECHNOLOGY INDUSTRIAL CO., LIMITED, which differs from the registered name only in capitalisation and punctuation and is treated here as the same company name. A separate earlier company name appears in the company website's own history section, and that earlier name is not the current company name: it is not used as the company name on this site, and the relationship between the earlier name and the registered name is one of the items awaiting customer confirmation. The brand name used on the site is Top-Trans, which the company website describes as its own brand registered in 2012; the brand is a brand layer only and is never used as the company name.
The company website describes itself as a Hong Kong-based business-to-business sourcing and supply partner for enterprise data center hardware and AI networking solutions, serving system integrators, cloud and high-performance computing teams, telecom operators, data centers and enterprise IT teams. That positioning sentence is quoted here as a company-website statement, and the history below is likewise company-website material rather than independently verified fact.
History as stated on the company website
The company website's history section states that the founder entered the fibre industry in 2006, that an earlier company was established in 2008, and that Topstar Technology Industrial was formally registered on 29 April 2008. It states that the first office opened in Futian in February 2008, that the business moved premises in 2011, that a brand was registered in 2012, that production capacity expanded in 2014, that the company exhibited at an optoelectronics exposition in 2021, and that it moved to a new headquarters in the Shenhui Building in April 2025. Each of those statements is a company-website statement, and the 2025 move section contains an internal date error in its own text, which is noted here rather than silently corrected.
The founding year is not stated as a single fact on this site, because the sources disagree. The company website states registration in 2008, while the store-side and third-party material gives 2011. Until the customer confirms which year governs, this site carries both positions with their sources and does not choose one. The store-side age figure of 17 years is likewise quoted as a store-page figure, not as a verified age.
Supplier identity and the manufacturing conflict
The store record for this business lists its Business Type as Trading Company, and this site describes the business as a supplier on that basis. The company website also carries manufacturing wording about its own research team, production lines and workforce numbers, including a factory area figure, research staff numbers and worker numbers that appear in its quality and product sections. Those two positions conflict, and they have not been reconciled. This site therefore quotes manufacturing wording only as company-website statements, flagged as conflicting with the Trading Company record, and it does not describe the business as a manufacturer, does not claim a factory of its own, and does not present any image as a photograph of this company's own factory.
Scale figures from the company website, including factory area, research staff and worker numbers, are quoted with their source and their year where the source gives one, and are not combined into a single current scale statement, because the figures come from different years and different sections. Revenue and monthly sales figures that appear in a product-page brand section are not published on this site, because they are single-section self-statements without independent verification and are not needed to specify a module.
Certification and commercial terms
Certification names stated by the company are ISO 9001, CE, FC, 3C and RoHS, with the company's own wording noting that the list is not exhaustive. Individual product pages add table entries for specific models, such as a CE entry for the bidirectional module and a RoHS entry for the 10G module. Certificates are available upon request, and no certificate numbers are published on this site, because none were published in the source material and the image filenames on a contact page are not certificate numbers.
Minimum order quantity and lead time at company level are unavailable on this site and are confirmed per model in the enquiry. Export country lists and customer cases are likewise unavailable: the company website names industries and customer types, not countries, and product-page mentions of customers are not reproduced as verified cases and no customer name is published here. A buyer who needs any of these items confirmed should name the item in the enquiry.
Enquiry checklist
Before sending an enquiry, note the model or the rate you need, the wavelength, the fibre type, the distance, the connector, the quantity and the application. State whether the module must be compatible with a named host platform, and name any certification document you need. Minimum order quantity and lead time are unavailable at company level and are confirmed per model in the enquiry. Quotations are confirmed per order.

Frequently asked questions
How do I get a quotation?
Send an enquiry naming the model, the rate, the wavelength, the distance and the quantity you need, plus the application. Quotations are confirmed per order, and specifications are confirmed per model before payment. This site does not list fixed selling figures, and no price is shown for any model.
What certification documents can you provide?
The company states ISO 9001, CE, FC, 3C and RoHS names. Certificates are available upon request. If a buyer needs a certificate for a specific model, name the model in the enquiry so the correct document can be checked. No certificate numbers are published on this site.
Do the specifications on one page apply to the whole range?
No. Specifications are shown per model and must not be read across the whole range. Where a value is not listed for a model, the page says to confirm per model rather than filling in a generic figure, and where the source pages disagree, the page flags the conflict instead of choosing one value as fact.
What are the minimum order quantity and lead time?
At company level both are unavailable on this site and are confirmed per model in the enquiry. A single-model note, where one exists, is marked as applying to that model only and must not be read as a company-wide term.
