Frequently Asked Questions

Quick answers about ordering, OEM, compatibility and support. Anything else — write to us, we reply within one working day.

What is your minimum order quantity?

We support sample orders and small trial orders — even 1–2 pcs for testing. Exact MOQ depends on the model; mixed models can ship in one shipment. Tell us your plan and we'll suggest the most economical quantity.

How long is the delivery time?

Lead time depends on the model, quantity, stock and customization. Ask us to confirm the production and dispatch schedule in your quotation and order confirmation.

Do you support OEM / ODM?

Yes. Private model numbers, silk-screen logos, customized firmware defaults, manuals and retail packaging — our partners in 60+ countries ship under their own brands.

Are your SFP modules compatible with major brands?

Yes — Cisco, Huawei, H3C, ZTE, TP-Link and more. Brand compatibility coding is free on request; with our own converters and switches they work out of the box.

Single-fiber (WDM) or dual-fiber — which should I choose?

Choose single-fiber BiDi when fiber strands are scarce or rental is expensive — one strand carries both directions. Dual-fiber is the economical default when two strands are available. Both reach 20–100 km; just match A/B wavelengths on single-fiber links.

How far can your devices transmit?

Multi-mode up to 550 m; single-mode 20 / 40 / 60 / 80 / 100 km options on converters, switches and modules. The two ends must match in wavelength and distance — send us your link details and we'll pair them for you.

What warranty do you offer?

Warranty duration and coverage depend on the model and the agreed order terms. Request the current datasheet and written warranty terms with your quotation.

Which payments and shipping methods do you accept?

Payment options, shipping method, freight charges and transit estimates are confirmed in the quotation and order documents. Send your destination and delivery requirements when requesting a quote.

Do you test every unit before shipping?

Testing procedures depend on the model and order. Ask us to confirm the burn-in duration, operating conditions, optical pairing or DDM checks, and available test reports before ordering.

Can you customize connectors, distance or temperature range?

Yes. SC is the default connector with FC/ST optional; custom distances from 2 km to 100 km; -40 ~ +85 °C industrial versions for harsh environments. Describe the project — we'll spec it.

Do you support OEM or ODM production?

Yes. We ship under your own brand, in neutral packaging, or under Huasnet branding — you choose. Silkscreen, retail boxes, manuals and firmware defaults are customizable from modest quantities. Ask for the artwork proof cycle and minimums per line.

How do you test products before shipment?

Testing procedures depend on the model and order. Ask us to confirm the burn-in duration, operating conditions, optical pairing or DDM checks, and available test reports before ordering.

What is the typical lead time?

Lead time depends on the model, quantity, stock and customization. Ask us to confirm the production and dispatch schedule in your quotation and order confirmation.

Can I mix different products in one container?

Yes — converters, switches, PoE units and modules consolidate in one shipment with one invoice and one packing list. Mixed orders are the normal case for our distributor customers.

Which fiber distances do you cover?

Multimode 550 m; single-mode from 3 km to 120 km in standard steps, with WDM single-fiber options that halve your fiber usage. Distance is configured per order — one hardware platform covers the range.

Are your SFP slots locked to your own modules?

No. Our SFP slots follow the MSA standard and accept any compliant third-party module. For switches known to enforce vendor coding, we pre-code our modules to match — tell us the target model when ordering.

What after-sales support do you provide?

For technical or warranty support, contact us by email or WhatsApp with the model, order number and fault details. Warranty handling and any replacement arrangements follow the terms agreed for your order.

Do you provide datasheets and documentation?

Every model has a datasheet with measured specifications, and documentation ships in your language option for volume orders. Tender-grade documentation packages are available for public-sector bids.
