Many buyers have questions. Why do sellers generally ask which compatible optical modules are needed when purchasing  compatible optical modules ? Today, our Fiberland company will explain this to you.   Because our optical modules are generally used with switches, and switches have many brands, such as Cisco, Huawei, China, Juniper, Hewlett-Packard, ZTE, Pulian, Youxun, Mikrotik, Planet, Extreme, Alcatel, Annette, etc. Wait. Different brands determine the compatibility of the media converter.   Many people have questions. Is there an optical module that is compatible with all switches? The answer is that the same optical module is not compatible with all brands of switches. Just like a lock with a key. The optical module plug-in switch is also the same principle. The compatible code of the optical module is like a key, and the switch is like a lock. Different compatible optical modules are compatible with different codes. For example, Huawei has its own compat...

CWDM SFP  (Coarse Wavelength Division Multiplexing) transceiver, used on SFP ports or slots on the switches or routers, is a technology that allows for multiple channels, of mixed protocols and data rates, to be COMBINED and transmitted over fiber optic cable.   CWDM SFP makes use of the SFP interface to connect the apparatus and also double LC/PC fiber connector software to connect the optical network.

A SFP (small form-factor pluggable) is a small transceiver that plugs into the SFP port of a network switch and connects to Fibre Channel and Gigabit Ethernet (GbE) optical fibre cables at the other end. By choosing the appropriate SFP module, the same electrical port on the switch can connect to fibres of different types (multimode or singlemode) and different wavelengths. If the fibre is upgraded, the SFP module is replaced.   What's the difference   SFP’s can be expensive due to their complex technical nature but possible more so to do with the brand name placed upon certain SFP’s, such as Cisco, Avaya and Brocade inflating the price tag. Why see your budget wasted on over-priced vendor transceivers, when all you need is a  Compatible SFP ?   Compatible SFP products are available for almost all brands and models and can be up to 80% cheaper than their branded counterparts. Compatible SFPs for all brands are specifically designed to meet to specificati...

by www.fiber-mart.com When setting up your network, the selection of devices is fundamental to determining the performance of the system. But those devices can't communicate without optical transceivers. If your network contains Cisco or Juniper routers, firewalls, and switches, you might assume that with such branded optics only is sensible, to make sure that all of your devices are compatible and processes optimally. However, that seemingly reasonable assumption could cost your company thousands of dollars. Compared to the compatible units produced by third (3rd) party companies, the transceiver units come with dramatically inflated prices. Compatible units are roughly 80 percent less than the branded optics.    Why Should You Choose Compatible Optical Transceivers? Let us take the  Cisco compatible SFP transceive r modules for example. Cisco compatible SFPs are simply a great throughout deal. Not many situations are this easy. So don't get this to difficult ...
