A Brief Introduction of Fiber Optic Transceiver

With the development of our society, optical fiber communication has become one of the main pillars of modern communication, it plays an important role in modern telecommunication networks. Fiber optic transceiver is one of the important parts in optical fiber communication. As it is known to us that fiber optic communication is a way of transmitting information from one place to another by sending light pulses through an optical fiber. During this process, optical transmitter converts electrical signal into an optical signal and sends it into the optical fiber, and an optical receiver to recover the signal as an electrical signal. Different types of fiber optic transceivers can be found on the market, but do you know how these transceivers are classified into specific categories? In this article, let's have a look at the explanation of these criteria used to classify fiber optic transceivers. According to the Packages Fiber optic transceivers with similar features are furthe

How to Maintain SFP Optical Module

SFP optical module contains many precise optical components and circuit components, we need to operate in accordance with the specifications, otherwise it is easy to cause damage to the optical module. We will introduce several methods of daily maintenance of optical modules for you. First, ESD protection should be kept in mind We must a good job of electrostatic protection (e.g. wearing anti-static gloves and anti-static bracelets to prevent electrostatic damage), try to contact the light module shell, instead of the contact light module PIN foot; Maintain the humidity of the light module at 30-75% RH. It is strictly forbidden to carry out live plug-and-pull operation on non-hot plug-in equipment. Secondly, the protection of smooth port should be paid attention to. Be sure to keep the end of the optical fiber connector clean. Optical module light outlet avoids long exposure. When not in use, cover the light plug. When not in use, the light plug is stored in a dustproof c

There are 5 troubleshooting tips about SFP+ compatibility issues

Have you ever tried to plug an optic SFP+ transceiver into an SFP+ port to discover that the connection didn’t work, i.e. traffic was very slow or there was no data transmission at all? Did you manage to diagnose the problem and find a resolution? There are several possible reasons for failure. We’ve listed the five most common ones. TIP 1: Check whether you’re using SFP or SFP+ transceivers and slots SFP and SFP+ modules look exactly the same. And as they have the same size, your SFP transceiver will fit seamlessly into an SFP+ switch port and vice versa. However, the connection won’t work as you expect it to. Or, worse even, it won’t work at all. If you plug an SFP device into an SFP+ port, the speed will be locked at 1 Gbps. Plugging an SFP+ module into an SFP port delivers no results at all, as the 10G transceiver can never auto-negotiate to 1Gbps. TIP 2: Ensure that the SFPs have identical wavelengths at both ends  Data transmission implies that data is sent from one end

Why is 10G SFP + optical transceiver so popular?

SFP + is the latest pluggable optical transceiver applied in 10Gbit/s Ethernet and 8.5Gbit/s optical fiber channel system. It is the most widely adopted standard in 10G optical transceiver standard. Three main reasons for the popularity of 10G SFP + optical transceivers are as follows: (1) Strong compatibility: The size of SFP + optical transceiver is the same as that of SFP optical transceiver, so any of the optical transceivers mentioned above can be used in SFP + port. (2) Small size: The size of SFP + optical transceiver is one tenth of that of XENPAK optical transceiver, which is the same as that of common SFP optical transceiver. (3) Low cost: SFP + optical transceiver can follow many specifications formulated by SFP standard, and the technology conforming to these specifications is very mature, so the manufacturing cost of new SFP + optical transceiver is low, and the power consumption of SFP + optical transceiver is very low, which also helps to save costs. SFP

16G VS 25G SFP+Optical Transceiver

Network is an important part of our life. As a network solution provider, energy saving and cost are two important factors to consider when deploying data center network. The rate of 10G optical transceiver can not meet the network demand, while the price of 40G and 100G optical transceiver is too high and the power consumption is too high. At this time, 16/25G SFP + optical transceiver with high performance and low price is very popular in data center. Cisco compatible DS-SFP-FC-16G-SW SFP+optical transceiver is mainly used in FC (Fibre Channel) network applications. It uses duplex LC interface and uses with multimode optical fibers. Its working wavelength is generally 850 nm, transmission distance can reach 100 m, transmission rate can reach 16 Gbps. In addition, the optical transceiver has backward compatibility, and can operate at 8.5 Gbps (8GFC) and 4.25 Gbps (4GFC). Cisco compatible SFP-25G-SR-SFP + optical transceiver is mainly used for 25G high-speed transmission, suitable
