As the saying goes, "every penny is worth a penny". To get good value for money, comparison is definitely the only way for high-quality buyers! For the purchase of optical modules, how to give full play to the strength of the fire eye? Today, let's talk about the essence of this!

The basic composition of the optical module consists of the following parts: optical device + main chip + PCB+ resistor / capacitor + electrical interface + shell

Comparative analysis of advantages:

Optical device market according to the iteration of products, the good and the bad are intermingled, in this mixed era, how to avoid falling into the trap of inferior quality? Let's simply classify optical devices according to their usage:

Brand-new optical devices: domestic chip packaging / imported chip packaging is transformed into TO, which is processed with adapters and pins to break the cocoon into optical devices.

Second-hand optical devices: optical module products eliminated from foreign data centers, dismantled PCB, re-flow to the market for circulation.

There is no data to define whether the device is new or old. Only when it is used for a long time can the problem of the product be found. Under the long-term high temperature work, the life of the optical device is constantly lost, so although the price of the disassembled and assembled optical device has a great advantage, there is a great hidden danger of communication in use, which leads to the interruption of signal transmission. a great waste of the late maintenance cost and time of the communication system.

Bad optical devices eliminated by large factories: as the maintenance of optical devices requires a lot of time / equipment and manpower, some powerful leading enterprises in order to improve production efficiency, abandon the retention of bad products, and eliminate some bad optical devices. this gives other companies in the industry a good circulation channel, through low-cost purchase, re-screening and maintenance, re-enter the market, undoubtedly do not add a vitality to the circulation market!

Main chips: imported chips / domestic chips are highly concentrated in the market, such as Macom/Maxim / Semtech/Marvell Marvell / UX Youxun and so on.

PCB: from the selection of the main chip to the PCB design, there is no doubt that it does not infiltrate the countless painstaking efforts and sweat of engineers.

The production of PCB from laser imaging, high-precision impedance testing, Yi Tianguang Communication's PCB partners have deposited 15 to 20 years of experience, these details protect the product from wind and rain in the application environment. Every detail will be outstanding, in order to facilitate customer identification, PCB will screen printing ROHS and UL certification logo, but also another milestone in product standardization and technological progress!

PCB copper cladding, its significance is to reduce the impedance of the ground wire, improve the anti-interference ability, reduce the voltage drop, improve the power supply efficiency, and connect with the ground wire to reduce the loop area. Suppliers rarely highly subdivide the details of these products, or even limit the use of materials, which is the truth of "goods for every penny". In order to ensure the signal stability and anti-jamming ability of the optical module, the R & D engineer of Yi Tianguang Communication has designed 3-4 layers of copper skin for our optical module.

Resistance / capacitance: in order to reduce the cost and greatly reduce the amount of resistance and capacitance, the protection circuit / step-down / shunt effect of resistance / capacitance is continuously reduced in some harsh application environment. Precise circuit design and reasonable resistor / capacitor layout can improve product performance (picture and truth).

Golden finger as the signal transmission messenger, by a large number of gold × × conductive contact piece composition, easy Tianguang communication gold finger gold plating requirements: 0.38um hard gold, with high-strength anti-plug resistance. As the saying goes, the golden tablet is not as good as the customer's word-of-mouth, the customer said good is really good. The customers of Yi Tianguang Communication have passed the high-intensity plug and unplug test, which proves that the number of plug and unplug of our optical module can be controlled at about 10000 times to ensure the more lasting use of the products.

The shell of zinc alloy is like every piece of our clothes, does it fit? Is the pull ring fastened and whether the electroplating paint is anti-oxidation? Is the plug and pull smooth? "the road knows horsepower, see the hearts of the people for a long time", the product is good for time to witness, with the use cycle will find the pros and cons of the product. The market will wash each floating factor, Yi Tianguang communication carefully pouring every detail, careful selection of materials, careful design, careful manufacturing, rest assured to use!

When everything is ready, all you need is packaging.

Only you can't imagine, there's nothing we can't do!

Feature 1: customize boxes of different sizes to avoid volume and weight in international cargo transportation and reasonably save freight costs for customers.

Feature 2: do you worry that your "love" will be broken beyond recognition in transit? Don't worry, when the goods are packed, we will put the fillers up and down, left and right, so that the products can be fully protected.

Feature 3: no matter it is independent packing, 5 pack or 10 pack, Yi Tianguang Communication is available for you to choose from. Who makes you God?

Be my God, let us spoil you!

No matter in the product transportation, or in the packaging and other aspects of the details, Yi Tianguang Communication (ETU-LINK) will be more careful, I hope our heart can win your move!

Friendship recommendation: 100g QSFP28 SR4 optical module
