Talk about 10G SFP + Copper Optical Transciever

The 10 Gigabit optical port conversion port module is also called 10G SFP + Copper Optical Transciever. This module is definitely created for high-speed communication links. Compared with ordinary optical modules, the power consumption of the 10 Gigabit optical conversion module can be that of ordinary optical modules. One-half of it, with stable performance, it can understand the 10G transmission network through the network cable, and is certainly widely used in 10 Gigabit Ethernet.

10G SFP + Copper optical module description:

10G SFP + provides RJ45 interface, which is mainly integrated in switches, network cards and other products, adopts full-duplex transmission mode with echo suppression, PAM16 pulse amplitude modulation technology, and the standard working bandwidth requirement is 417MHz.

It is mainly used to complete 10G Ethernet transmission in CAT6A or CAT7 copper cabling system. It conforms to SFF-8431 and SFF-8432 MSA standards, and the maximum transmission distance can reach 30m. In addition, compared with SFP + high-speed cables, 10GBASE-T SFP + electrical optical modules can save at least 0.5W of power consumption, and its RJ-45 interface can support both shielded twisted pair and unshielded twisted pair.

SFP + high-speed cable VS 10G SFP + electrical port optical module VS SFP + optical module:

1. The link distance between devices in most data centers is now between 10m and 100m, and the use of 10G SFP + Copper optical transciever can make up for the lack of SFP + high-speed cable transmission distance.

2.10G SFP + Copper optical transciever adopts RJ45 interface and is utilized together with Category 6 or Category 7 network cables. The price of copper cabling is normally lower than that of optical cables.

3.10G SFP + Copper optical transciever can be directly used in the existing copper cable wiring system to accomplish 10G transmission, while using SFP + optical module requires optical cable for wiring, that may boost the deployment cost. If you want to use SFP + optical modules in the prevailing copper cabling system, you have to add devices such as Ethernet switches or photoelectric converters.

The note for we choose a 10G Copper optical transciever:

1. There is a choice of multi-rate or single-rate. 10G rate electrical port modules, some support multi-rate (1-10Gb / s), or only support single rate (10Gb / s).

2. The working temperature range is different. There are commercial grade and industrial grade 10G electrical port modules. The commercial grade operating temperature range is 0-70 ℃, and the commercial grade operating temperature range is -45-80 ℃.

3. The main chip differs.

Application scenarios of 10G SFP + Copper optical transciever:

The RJ-45 and SFP + module interfaces cannot be directly interconnected. An SFP + module to RJ45 interface converter is required. The 10G Copper optical transciever is such a converter. Through the 10G Copper optical transciever and Cat6 network cable, the RJ-45 interface 10 Gigabit electrical network card could be interconnected with the SFP + interface 10 Gigabit switch.

How to use: First insert the 10G Copper optical transciever into the SFP + interface 10 Gigabit switch, and then directly use the RJ45 interface network cable to successfully connect the 10 Gigabit network card and 10 Gigabit switch.

Differences between cisco GLC-T and cisco GLC-TE

 Cisco GLC-T, GLC-TE and SFP-GE-T optical modules are all Gigabit port optical modules with RJ45 interface and 100m transmission distance. They are cost-saving solutions for Gigabit Ethernet connection in data center, access network and storage area network applications. Therefore, these three types of optical modules are often difficult to distinguish. In fact, the transmission effect of these three optical modules is the same, which optical module can achieve Gigabit transmission, but it is certainly noteworthy that the original Cisco GLC-T and SPF-GE-T optical modules were terminated on June 1, 2017 and replaced by GLC-TE optical module. SFP-GE-T optical module with NEBS 3 ESD function needs to be selected if it is traded directly with the telecommunications company (which requires NEBS).The price of GLC-T and GLC-TE optical modules is low, and they can also meet the needs of Gigabit Ethernet. The Cisco Gigabit optical modules provided by Easy Communications can meet a large number

Why the sfp transceiver not work

 The failure of the sfp optical module is divided into the failure of the transmitter and the failure of the receiver. Through the analysis of the main causes of the phenomenon, the most likely problems are mainly concentrated in the following aspects: The optical port of the  1000base SFP transceiver  is contaminated and damaged Because of the pollution and damage of the optical interface of the module, the loss of the optical link is increased, so that the optical fiber link is unreachable. The main reasons for this phenomenon are the following four points: 1. The optical port of the SFP optical module has been exposed to the environment for a long time, resulting in contamination and contamination of the SFP optical port; 2. The end face of the fiber jumper connected to the  Cisco SFP-10g-sr  optical module has been contaminated, and the SFP optical port provides been contaminated; 3. Improper operation of the end face of the optical connector with pigtails, scratching of the finish
