Knowledge of The Fiber Optical Module Compatibility

Compatible fiber optical modules have been welcomed by the majority of users. Next,we answer the common questions about compatible fiber optical modules.


1. What is the difference between fiber optical module and the original fiber optical module?

There is not much difference between the two. Because all fiber optical modules are manufactured based on multi-source agreement (MSA). The only difference is that the vendor code in EEPROM (Electrically Erasable Programmable Read-Only Memory) is reset to the system owned by the vendor. This means that the connected fiber optical module must have the same EEPROM code as the original supplier's network equipment. Third-party fiber optical module vendors can independently decode and write codes through the analysis of fiber optical modules. An OEM can add only one or a few codes to the fiber optical module. Excellent compatible fiber optical module vendors can master the codes of multiple OEMs at the same time. Compatible fiber optical modules from multiple OEMs are provided, making it much easier to purchase and install fiber optical modules.

Sopto can provide many types of compatible fiber optical modules, including SFP, SFP+, XFP, SFP28, QSFP+ and QSFP28, compatible brands include Cisco, Huawei, H3C, ZTE, HP and so on.

2. Why is fiber optical module compatibility so important?

Because some industry manufacturers (such as Cisco and Hewlett-Packard) encrypt their network equipment (such as switches), these network equipment has high requirements for the compatibility of fiber optical modules. This means that Cisco fiber optical modules cannot be used with HP networking equipment, and vice versa. At present, the price of branded fiber optical modules on the market is usually higher than that of third-party fiber optical modules. However, because third-party fiber optical modules are compatible with branded network equipment and can provide the same performance as branded fiber optical modules, they are widely used in data centers, Enterprise network and campus network. Since branded network equipment has high compatibility requirements, it is very important for third-party suppliers to ensure that third-party fiber optical modules are compatible with branded network equipment. So when purchasing, most suppliers will first ask you which brand you need to be compatible with.


3. Why are compatible fiber optical modules so popular?

The main reason is the price advantage. Compared with well-known brands, such as Huawei, Cisco, etc., the cost of compatible fiber optical modules is greatly reduced. Using compatible fiber optical modules can not only save a lot of money, but also achieve the same effect and strong compatibility. , The operation is stable, for the buyer, why not do it?


4. The original equipment purchased is discontinued, what should I do if there is no fiber optical module sold?

It is estimated that this problem cannot be solved by the equipment manufacturer, but the compatible fiber optical module supplier can definitely solve it for you. Even if it is an old device, the compatible supplier can also equip you with a new fiber optical module to extend the service life of the device.
