Home>Service>Warranty Term
We offer a lifetime warranty on all of our products. Every optic that we ship out is fully guaranteed for compatibility and operability.

Our quality control procedures are designed to ensure virtually zero chance of failure in your network. However, should you experience any problem with one of our optics, our technicians will work to timely resolve the matter, or issue an advanced replacement unit if necessary. We will send an advanced replacement to keep your network running smoothly and coordinate the return thereafter, so you will not lose valuable time waiting for the original optic to be received by us.

RMA process

1. Obtain an RMA

Fill out an "RMA request form" and send it by email to the corresponding RMA person. If you do not know who the correct contact person is, please check TEOSCO web site or contact your sales representative.

If you need a defective product to be replaced rather than wait for the defective product to be repaired, this must notify our sales representative and corresponding RMA person at the same time.

2. Package and Delivery

Returned products have to be packed properly to avoid damage during delivery.

A copy of RMA request form must be delivered along with the RMA products.

3. Product Check on Arrival

TEOSCO RMA operator will check your product within eight hours of its arrival.

If the product arrives undamaged and conforms to the conditions described on the "RMA request form", it will be transferred to TEOSCO repair engineers for repairing.

If the product is damaged or there is some inconsistency with the "RMA request form" description, we will contact and confirm the status with the customer before proceeding.

4. Repair

The repair engineer will repair the defect as described by the customer. The product will also be tested to ensure it is in proper working order.

Repair engineers will provide a repair report for RMA products that will be charged.

5. Package and Shipping

RMA operator will properly pack the repaired RMA product along with a repair report and the copy of RMA request form.

The customer will receive email notification of the request form.
