Optical modules and fiber jumper selection of storage area network
Posted on May 24, 2017 by cozlink.com
Optical modules and fiber jumpers are the most important infrastructure for network connectivity. In the storage area network (SAN), a switch is used between the server and the storage device, that is, interconnections between the server and the switch, the storage device, and the switch as well as between the switches are achieved by optical modules and fiber jumpers. Of course, depending on the specific application, we have to choose the most appropriate optical modules and fiber jumpers in order to achieve the best performance. In addition to considering the performance, we also need to take the future expansion of the network and other issues into account. Therefore, it is necessary to develop a cost-effective optical module and fiber jumper solution.Key factors that affect the selection of optical module and fiberAs we mentioned above, the SAN is mainly composed of servers, storage devices, and switches, then we have to take into account the specific circumstances of the server, s..
Guide of Installing/Removing the SFP RJ-45 Optical Module
Posted on May 27, 2017 by cozlink.com
The optical module integrates precise optical elements and circuit elements. In the daily use, operation by specification should be noticed; otherwise, the optical module is easily broken. Do you know that there is SFP electrical port module in SFP optical module? How to install and remove SFP electrical port module? The article will give a detailed introduction to the specification of SFP electrical port module's installation and removal.1. Introduction to SFP Electrical Port ModuleOne terminal of SFP RJ-45 module is SFP gold finger connected with the main engine, and the other terminal is common LC interface connected with the optical patch. But sometimes live environment requires using RJ45 interface to connect with a copper network cable. But Internet interface of the device is not enough. Then SFP interface must be transited toRJ45 interface. The former is such an application that one terminal is SPF gold finger and the other terminal is an RJ45 interface with the general speed ra..
SFP optical module (Small Form-factor Pluggable) can be easily understood as an upgraded version of the GBIC optical module. SFP optical module is half the size of the GBIC optical module, which is only the thumb-size but can configure on the same panel more than double ports on the same panel. The other functions of the SFP optical module are basically the same as those of the GBIC optical module.1. Components of SFP Optical ModuleSFP optical modules are mainly composed of lasers (including transmitter TOSA and receiver ROSA), circuit board IC and external accessories. The external parts are mainly composed of the shell, the base, the PCBA, the pull ring, the buckle, the unlocking piece and the rubber stopper. In order to recognize conveniently, the parameter type of the optical module is generally distinguished by the color of the pull ring.2. SFP Optical Module MaintenanceSFP optical module covers a lot of sophisticated optical components and circuit components. Therefore, the user ..
