Q: Can Goilips provide custom compatibility coding?
A: Yes. Provide the host brand, device model, operating-system version, and required part number. We will confirm the compatibility profile before production and can support on-site recoding for applicable products.
Q: How do I find a product by Model?
A: Enter the complete or partial Model value in the product-page search box. If no result appears, send the Model and host-device information to our sales team for confirmation.
Q: How do I get a better price?
A: Open Contact Us, select the relevant inquiry topic, and provide product models, quantities, compatibility requirements, and destination. Our team will respond with availability, price, and lead time.
Q: Do you accept small-batch or sample orders?
A: Yes. Most standard products support sample and small-batch orders. Minimum quantity and lead time may vary for customized products.
Q: Are discounts available for volume purchases?
A: Yes. Pricing is evaluated according to product type, quantity, delivery schedule, and customization requirements. Submit your bill of materials for project pricing.
Do you support OEM, private labeling, and custom packaging?+
Yes. We can support labels, packaging, private-brand presentation, compatibility coding, and selected specification customization after technical review.
Can I change or cancel an order?+
Contact your account manager as soon as possible. Unproduced standard items may be adjusted, while completed, shipped, or customized products may not be cancellable.
What is included in the displayed product price?+
Displayed prices are catalog references. Freight, tax, duties, customization, and project-specific services may be quoted separately. The confirmed quotation or invoice is final.
Which payment methods are supported?+
Available methods may include bank transfer, wire transfer, credit card, PayPal, or approved account terms. Options depend on destination, order value, and account status.
How long does preparation and shipping take?+
In-stock standard products are normally prepared quickly after payment confirmation. Production and customized orders require a confirmed lead time; international transit depends on carrier and destination.
How do I obtain my tracking number?+
The tracking number is provided by email or your account manager after the carrier collects the shipment and tracking data becomes available.
How can I track my shipment?+
Enter the tracking number on the DHL, FedEx, UPS, or designated carrier website. Contact us if tracking is not updated for an extended period.
How should I install or remove an optical transceiver?+
Confirm the module and port type, use ESD protection, remove the dust cap, insert the module until latched, and connect a clean matching fiber. Release the latch before removal and never pull the fiber cable.
What ESD precautions are required?+
Wear a grounded antistatic wrist strap, handle the module by its housing, avoid touching electrical contacts, and keep unused modules in antistatic packaging.
How should optical ports and fibers be cleaned?+
Use approved lint-free swabs or one-click cleaners. Inspect and clean both connector ends before connection, and keep dust caps fitted when ports are unused.
What should I do if the module is not recognized?+
Confirm compatibility coding, port support, firmware version, and insertion status. Reseat the module, test another supported port, and collect device logs if the warning remains.
Why can the optical link not be established?+
Check that speed, wavelength, fiber type, connector, FEC mode, and BiDi transmit/receive pairing match at both ends. Also verify optical power and fiber polarity.
Why does the link frequently disconnect?+
Common causes include dirty connectors, marginal optical power, incompatible FEC, damaged fiber, excessive temperature, or unstable host ports. Record DDM data at both link states.
What should I do when optical power is too low or too high?+
For low power, inspect loss, connectors, bends, distance, and transmitter output. For excessive power, verify the link budget and use an appropriate optical attenuator if required.
How do I troubleshoot CRC, FEC, or BER errors?+
Verify matched speed and FEC settings, clean the optical path, inspect power margins, replace suspect patch cords, and compare error counters using a known-good module and port.
Why is DDM/DOM information unavailable?+
Confirm that the module, host port, and network OS support diagnostics and that monitoring is enabled. Some host systems restrict third-party diagnostic access.
What logs and diagnostics should I collect?+
Provide the device model, OS version, port configuration, module EEPROM/DOM output, optical power, temperature, alarms, error counters, topology, and test steps already performed.
