What are the types of SDI SFP Transceiver Module?

SDI SFP Transceiver Module could be divided into different categories according to different factors. For example, according to different operating wavelengths, they could be split into three types: 1310nm, 1490nm, and 1550nm. According to the different types of transceivers, SDI SFP Transceiver Module can be divided into five types: single-receive, dual-receive, single-transmit, dual-transmit, and transceiver-integrated. According to different transmission rates, they may be split into three types: 3G-SDI, 6G-SDI and 12G-SDI SFP optical modules.

3G-SDI is an upgraded version of HD-SDI, with a rate of 1.485G (also called 1.5G, corresponding to SMPTE-292M standard, supporting 720P) and 2.97G (also referred to as 3G, corresponding to SMPTE-424M standard, supporting FULL HD Full HD 1080P /60HZ). 3G-SDI supports the transmission of serial digital video signals and DVB-ASI (EN50083-9) digital video signals that comply with standards such as SMPTE-424M 3Gbps HD-SDI, SMPTE-292M HD-SDI or SMPTE-259M SDI. Similar to HD- SDI, 3G-SDI is also used in TV studios. With the upgrading of technology, it is also widely used in global security applications such as for example high-end surveillance and unattended systems.

The data rate of the 6G-SDI SFP Transceiver Module is twice that of the 3G-SDI Transceiver, which means that it has a higher transmission rate. Therefore, the 6G-SDI SFP optical module isn't only made for SMPTE 259M, SMPTE 344M, SMPTE 292M and SMPTE 424M serial digital video signals, but also can be used for SMPTE 2081 digital interface. In addition, 6G-SDI SFP Transceiver Module are also commonly found in cameras, video, security monitoring applications and 4K/HDTV/SDTV service interfaces.

12G SDI Transceiver Module is composed of three parts: DFB laser, and a PIN photodiode transimpedance preamplifier (TIA) and a DDM transceiver IC and MCU control unit.

12G SDI Transceiver Module can be utilized in the following 12G-SDI digital serial ultra-high-definition baseband signal application scenarios:

In the field of high-definition digital broadcasting, such as digital video transmission of digital output ports of high-definition professional cameras of TV stations, digital TV, live broadcasting of events, and live broadcasting of large-scale performances. The advantage of ultra-high-definition video is definitely that it includes a very strong sense of presence and actuality. It has the most delicate and realistic reproduction of real scenes. Especially for the transmission of extremely demanding sports events, ultra-high-definition display can achieve a very real visual sense.Read more:https://www.oemfibers.com

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
