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 ..
How to choose the 40G QSFP + optical module in the multimode connection applications?
Posted on Jun 06, 2017 by cozlink.com
Nowadays, with the rapid development of science and technology and the continuous improvement of user's needs, 40G applications in the communications industry are becoming more and more widely, at the same time, servers, switches, optical modules and other devices are also upgrading, the solutions for multi-mode application QSFP + Optical module are also more and more. Choosing the right 40G QSFP + optical module in a multimode connection application not only provides high performance, but also saves money. This article will explore how to choose a 40G QSFP + optical module for multimode connection applications.1. Multi-mode application under the 40G QSFP + optical module typeIn the 40G short-range multimode connection applications, there are three commonly used optical modules on the market, namely 40GBASE-SR4 QSFP + optical module, 40GBASE-CSR4 QSFP + optical module and 40GBASE-SR BiDi QSFP + optical module, the detailed parameters are as follows:
As a widely used and powerful optic component, optical modules are irreplaceable in fiber optic communication. With the increase of demands for bandwidth and performance of fiber optic communication and network system, the types and performance of optical modules are getting rich and strong, how to identify an optical module and know if it is good and proper for your demands? Take QSFP-SR4-40G as an example, even people know this module support a great performance, but few of them can seize the point of why and when you should choose this optical module. Here are about the whole things you have to know the answer to above question.1. Package typeQSFP-SR4-40G optical module is packaged by the type of QSFP+ (Quad Small Form-factor Pluggable Plus), that is the four-channel small pluggable optical module. This type of package is created to meet the demands for higher density and high-speed pluggable solution. The whole system includes a 38PIN connector, EMI shielding assembly, optical tran..
