People who often buy optical modules know that optical fiber modules usually need to confirm the compatibility code, because there are currently two types on the market, one is a high-performance compatible module, and the other is an optical module of the original switch brand. The price gap between the  two Larger.Next, JHA Technology will introduce to you the compatibility of optical modules.

First of all, in fact, the high-performance compatible module and the optical module manufacturer of the original switch brand optical module are the same. Whether it is a brand or a third-party manufacturer, please refer to the specialized optical module manufacturer (ie, the foundry factory) according to the market. The optical module made by the protocol and standard. Those that do not meet the requirements will not be accepted by the market and will be eliminated directly, because the modules produced by the OEM of the foundry are the same as the products sold to other brands.

To give a direct example, dual-fiber SFP+ 10km, the original manufacturer’s cost ex-factory price is about ￥80, after the label is posted, due to the brand effect and the dealers, layers of agents, the price is already the ex-factory price in the hands of customers Many multiples. It is conceivable that if the customer purchases directly from the processing factory, how much cost can be saved.

However, although the price of branded optical modules is expensive, there are other reasons why it is expensive. Some innovative improvements will be added to the technology of standardized components of OEMs, such as changing the link setting sequence, verifying legitimate components with encryption keys, strengthening the link detection scheme with special/non-standard components, and in the network operating system The whitelist is implemented so that the switch only accepts the optical modules made by the company, so that users can only choose their supporting products.

However, third-party module vendors can independently decode and write codes through the analysis of the modules. Basically, an OEM can add only one or a few codes to the module. Compatible module vendors can master the codes of multiple OEMs at the same time and provide Compatible modules on multiple OEMs make it much easier and more convenient for customers to purchase and install, but the cost has not increased much.

How to test the compatibility of compatible optical modules?
The optical modules provided by Shenzhen JHA Technology Co., Ltd will undergo a switch compatibility test before shipment to ensure that each module is 100% compatible. We provide switches compatible with major brands of network equipment, such as Cisco, Juniper, Huawei, HP, H3C, Alcatel, MikroTik, etc.

The quality of the optical module can directly affect the transmission effect of the optical fiber link. Although the quality of the original optical module is very good, its price is very expensive. At present, the compatible optical modules provided by many suppliers are completely comparable to the original optical modules, and the price is very advantageous, which can help users save a lot of costs.
