When choosing a compatible optical module, about 90% of users are worried about its quality and compatibility. As we all know, the price of compatible optical modules is much lower than the original one, so is the quality of compatible optical modules guaranteed? Can it be comparable to the original module? ETU-Link will give you some practical advice aimed to help you choose compatible optical transceiver with high compatibility and low cost.

Main Concerns for Buying Compatible Optical Transceiver:

Compatibility: Can it be well compatible with your switch equipment

Service life: If the quality of the optical module is not reliable, the service life will be very short

Poor performance: Signal transmission instability or signal delay

Refurbished modules: Large power consumption

How to Ensure Quality of Compatible Optical Transceiver?

1. Professional testing process

In order to ensure the quality of optical modules, our products will have some strict tests before shipment, including material test, parameter test, distance test, switch test and aging test.

v Material test: Testing the material, such as TOSA, ROSA and BOSA, it can reduce reject rate.

v Parameter test: Testing the module parameters, like output power, sensitivity, extinction ratio and eye diagram, the excellent parameter make the products working more steady.

v Distance test: For different transmission distance, our engineer will test the module by different meters of optical fiber, the customer no worried about loss pocket.

v Switch test: Insert the module to the switch to check if work normally and audit the eeprom information.

v Aging test: Install the module to the aging board, then working on it about 24 hours.

2. Long term warranty

If the warranty time is long, the products’ quality may be more reliable and stable. ETU-Link’s warranty is 3 years.

3. Reputable supplier

A reputable suppliers usually have strict quality control systems and OEM experience for many years, all the materials used are also very safe, can guarantee a stable and reliable connection in the network transmission system.ETU-Link is such a supplier.

Besides the considerations mentioned above, knowing the structure details requirement of a good compatible optical transceiver may also help you a lot.

v High quality laser: The high-quality laser is with high sensitivity and low attenuation, which ensure the perfect signal transmitting and receiving.

v Advanced chips: Advanced chips can provide high performance and low power module solutions to ensure high speed of signal transmission and stable performance.

v Gold finger: The industry gold plating standard is 0.38um, our hardware engineer is very strict on this, the thickness must be over 0.38um. Through customers’ verification, our products can be plugged for 7 days, others for 2 days.

When you want to upgrade your network, it is very wise to choose a compatible optical module to help save cost. ETU-Link——a professional manufacturer of compatible optical transceiver, may be your ideal choice.
