Inspection Service

Is it possible that we ourselves learn how to make Inspection Service, which we can create a service center in our country, because I think it will be important for our customers?

Re: We agree with you the best quality and after-sales service for customers is the basis of expanding our business. We’ve been dedicated to customer-oriented service and the development of trustworthy relationship, so we could do our products have been tested rigorously before shipments.

Reason and Maintenance methods:

A1.1 Emission component TOSA is bad. Maintenance method is to replace the TOSA.A1.2 The TOSA PINs PD+ is welded badly so that the power is so large. But when debug the software, the power won’t be changed. Maintenance method is to weld the pin better.A1.3 Power and resistance don't match with the BIAS optical bias current. Maintenance method is to improve the power and resistance. A2.1 Emission component TOSA is bad. The maintenance method is to replace the TOSA.A2.2 Paste is bad or poor performance of driver chip. The repair method is to re-paste driver chip or to replace the chip.A2.3 Power and resistance don't match with the BIAS optical bias current. Maintenance method is to reduce

Reason and Maintenance methods of common problem of optical module externally

1. Power light does not light.Reason: Power supply fault. Maintenance method: Replace the power supply. 2. Link lights are not lit.Failure may be as follows:(A) Check whether the fiber lines circuit breakers(B) Check whether the fiber line loss is too great, over equipment reception range(C) Check whether the optical interfaces are connected properly, local TX and RX connections from afar, TX and RX connections of the local in the distance.(D) Check whether the optical fiber connector intact, insert a device interface, jumper type matches the device interfaces, device type matches the fiber, equipment transfer length matches the distance. 3. The circuit Link light does not light.Failure

Important reason for the optical module functional failure

1. Optical Interface is polluted and damaged.The pollution and damage of the optical interface causes the optical link loss become large, resulting in the optical link fails. Reason as follows:A. The interface is explored in the environment so that the dust pollutes the interface.B. The fiber connector which is used has been polluted so that it causes the secondary pollution.C. Improper use of the interface of the optical connector with pigtail. D. The use of poor quality fiber optic connectors. 2. ESDM damageESD is the abbreviation of Electro Static Discharge.  ESD can produce tens of kv/m of electromagnetic pulse and even more.Static electricity will absorb dust, changing impedance
