main types of QSFP28 optics 100G SR4, 100G PSM4, 100G LR4, and 100G CWDM4

Can QSFP+ Optics Be Plugged on the Port of QSFP28?

100G Ethernet is developed at a fast pace. With the prevalence of 100G network, various issues happen in the process of network establishment. For example, 100G QSFP28 optics commonly used in daily life can be available for 10kms transmission distance in 100G applications via WDM tech. However, there is a non-negligible fact that the price of a WDM device is…

SFP-25G-SR and SFP-25G-LR SFP28 Optical Transceivers for 25G to 100G Migration

25G Ethernet was treated as the “new” 10GbE technology once it came out in 2014. Similar to 10G Ethernet that was based on 1 x 10Gbps lane scheme, 25GbE physical interface delivers 1 x 25Gbps more data. 25GbE technology with one single lane obviously improves the port density and cost requirement. 25GbE network supports several 25Gbps capable form factors, such…

Migrate to 40G Ethernet With SMF and MMF 40G QSFP+ Transceiver 1

Migrate to 40G Ethernet With SMF and MMF 40G QSFP+ Transceiver

Due to server consolidation, virtualization, and performance improvements, data center designers are eager to migrate from 10G to 40G to better meet their network demand. However, there are many 40G optical transceivers and cabling solutions available for sale, such as QSFP-40G-SR4, QSFP-40G-LR4, QFX-QSFP-40G-ESR4, as well as QSFP DAC/AOC cables. So, which one is the most cost-effective solution? No one can…

Considering Three Aspects Before Migrating to 40G

The dramatic growth of bandwidth requirements in data centers has led to the worldwide use of higher-performance optical products for network scalability, management, flexibility and reliability. Currently, 10GbE (Gigabit Ethernet) can’t meet the increasing needs of high speed transmission well for such applications as Big Data, cloud and Internet of Things being introduced in many industries. As such, network migration…

Finisar Introduces Quadwire

Finisar Corp. has introduced Quadwire, a 40- Gbit/sec optical link for data centers and high-performance computer clusters. Quadwire is a parallel active optical cable that provides a 40-Gbit/sec aggregate link via four 10- Gbit/sec full-duplex channels. Based on the industry-standard QSFP form factor, the new cable utilizes fiber-optic technology to transmit parallel high-speed data over ribbon multimode fiber.
