Optical Transceivers Introduction
With the development of the optical communication industry,new technology and cost-saving solutions are derived.Such as the widely used of CWDM and DWD.Today we learned about CWDM and DWDM. CWDM is a low-cost WDM transmission technology face to the access layer of metropolitan area network.Saving fiber resources and networking cost.It solves two problems:1.The shortage of optical fiber; 2.Multiser...
Some customers want to know about the difference between multimode and single mode SFP , so we summarize some information about multimode and single-mode.The following is some concepts and the differences between multimode and single-mode SFP. According to the wavelength,there are 850nm / 1310nm / 1550nm / 1490nm / 1530nm / 1610nm.850nm wavelength is fit for multimode SFP, transmission distance is...
With the rapid development of optical communication, most of manufacturers devote to 25G switch. Eg: HUAWEI CE8860---the industry's first 25GE access TOR switch.CloudEngine 8860(CE8860)series switch is a new high-performance, high-density, low-latency flexible card Ethernet switch. CE8860 switches provide high-density 100GE/40GE/25GE/10GE ports, support data center characteristics and high-perform...
ETU VS Others As the customers’ communication, some times we met two frequently questions: 1. What are the advantages? 2. Why choose us? In order to make the answer easily to get, the answer as below: ETU VS Others : A. PCBA design: Our PCBA passed ROHS and UL (94V-0) certification,few people will make the mark. The engineers come from the CISCO OEM partner, he strictly request the supplier to pri...
In order to make the people learn the difference between SFP+ and SFP、XFP, and avoid unnecessary trouble to the customer, so we share some information for them . 10G optical module has experienced the development from 300Pin, XENPAK, X2, XFP, finally realize the transmission of 10G signal with the same size as SFP, this is SFP+. SFP+ meets the requirements of the equipment to optical module high-d...
With the development of optical telecom market, more and more customers begin to pay attention to the stability and reliability of the optical transceiver . There are three kinds of optical transceivers on the market now: * Original optical transceiver * Second-hand optical transceiver * Compatible optical transceiver As we know, the price of the original optical transceiver is rather expensive, m...
As a sales of optical transceiver should know that the working temperature will influence the parameters of the optical transceiver.When the applied environment temperature of the module is changed, then the working current will change as the temperature changes. At the same time, it will lead to changes in the parameters of the optical transceiver.Thus affecting the normal transmission of the opt...
The small form-factor pluggable (SFP) is a compact, hot-pluggable transceiver used for both telecommunication and data communications applications. The SFP transceiver contains a PCB that mates with the SFP electrical connector in the host system. The form factor and electrical interface are specified by a multi-source agreement (MSA). It...
With the optical fiber application develop, the CWDM and DWDM was designed in the optical network . The early fiber optic transmission systems put information onto strands of glass through simple pulses of light. A light was flashed on and off to represent the “ones” and “zeros” of digital information. The actual light could be of almost any wavelength (also known as color or frequency) from rough...
In order to make the new partner learning the optical module interface easily, so summarize some useful information as below : The Interface Type of Fiber Optic Module: Dual fiber interfaces, Single fiber interfaces and RJ-45 interfaces. 1. Dual-fiber interfaces : The common...
