Contact Shenzhen Topstar Technology Industrial Co., Ltd.
Use the sales contact and the enquiry form on this page to ask about a model, a rate, a wavelength, a distance or a compatibility question. Please include the full link parameters in your message, because a rate alone does not select a module and a quotation cannot be confirmed from a rate alone.
Sales contact
The sales contact for enquiries is Ms. Vicky Tian, Sales Manager, telephone +86 19860146913, email dsale@topsfp.com, with the office telephone 86-0755-82552969. The same office number is also shown as the fax number on the company website, and it is reproduced here as shown there. The founder of the business is background only on this site and is not a sales contact: please do not address sales enquiries to the founder, and no sales telephone or email is published for the founder here.
Instant messaging accounts that appear on the company contact page are not published on this site. Enquiries should use the telephone numbers, the email address or the form on this page, so that the enquiry, the model and the confirmation stay in a single written record that both sides can refer back to.
Address
The current address published on this site is 12F1202-1203 Shenhui Building, Maantang Community, BanTian Street, Longkong District, Shenzhen, China, as shown on the company website, including the district spelling as shown there. An older address from a third-party register is not published alongside it, because the two addresses differ in building and community and publishing both would leave a buyer unsure which address governs. A factory address line that appears on the company website names a district-level factory location without a street number, and it is reproduced on the About page only as a company-website statement, without a street number added.
Office hours stated on the company website are 9:00 to 18:30 Beijing time. Enquiries sent outside those hours will be answered in the next working period, and an enquiry that needs a quotation should include the full model and link parameters so that it can be answered without a second round of questions.
What to include in your enquiry
A complete enquiry names the model or the rate, the wavelength, the fibre type, the distance, the connector, the quantity and the application, plus the host platform when compatibility matters and any certification document needed by name. Minimum order quantity and lead time are unavailable at company level and are confirmed per model, so an enquiry that asks for both per model will be answered faster than one that assumes a company-wide term.
Prices are not published on this site for any model, and quotations are confirmed per order. A quotation request should therefore state the quantity and the delivery location as well as the model, because quantity and location affect the quotation and neither can be inferred from the model name alone.
Enquiry form
Use the form below, or contact the sales contact named on this page. Please include the model, rate, wavelength, distance, connector and quantity in your message.
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.
