OEMfibers QSFP28 CWDM4 Optical Module Overview

 100G CWDM4 is also a multi-source protocol (MSA). The 100G CWDM4 optical module introduces WDM technology and uses a duplex LC interface. When used with single-mode fiber, the transmission distance can reach 2km.

The transmission rate of the 100G QSFP28 CWDM4 optical module is 103.1Gbp, which is mainly used in computing, high-frequency trading and other fields. Its cost is definitely significantly higher than that of the QSFP28PSM4 optical module. Through coarse wavelength division multiplexing (CWDM) technology, the QSFP28 CWDM4 modules multiplexes four wavelengths of 1270nm, 1290nm, 1310nm and 1330nm onto a single mode fiber for transmission.

1.Optical module package

The optical module package found in the 100G QSFP28 CWDM4 optical module is QSFP28, which is an optical module that can be used to support 100G transmission. It provides an ideal solution for the ever-increasing transmission rate of ultra-large data centers. The package size of QSFP28 optical modules can be smaller than that of CFP4. The smaller optical module means that the QSFP28 optical module has a higher port density on the switch.

2.Digital Diagnostic Function

The 100G QSFP28 CWDM4 optical module has built-in digital diagnostic function, which can effectively monitor important performance parameters such as optical power, received optical power, temperature, power supply voltage, laser bias current and warning information.

3.Cost

The 100GQ SFP28 CWDM4 optical module can be directly upgraded from 25G to 100G without 40G, which greatly reduces the expense of the wiring system.Know more: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
