QSFP BiDi — 40GbE Over LC Duplex Multimode Fiber

Growing data center consolidation, higher-performance servers, and increasing application density on virtualized servers are driving network capacity demands to levels previously unimagined. The data center network is shifting to 10 Gbps at the access layer and 40 Gbps at the aggregation layer. However, to support 40Gbps connectivity, data center architects need to upgrade the cabling infrastructure. This could be too expensive or disruptive to allow data centers to quickly adopt and migrate to ...

10G-40G Migration: Saving With 40G SMF&MMF QSFP Transceiver

The compelling demand for high-bandwidth application pushes data center to greater capacity—from legacy 10G Ethernet to more dense 40G Ethernet network. However, one challenge facing 10G-40G migration is the reduced reach of OM3/OM4 cable: OM4 can reach up to 400 m on 10GBASE-SR transceiver, but for 40G QSFP SR module, the link distance is decreased to 150 m. So we have to re-design or modify the data center to extend the reach. In this case, 40GBASE-UNIV SMF&MMF QSFP transceiver emerges as ...

Development of 40GBASE iSR4 QSFP+ Transceiver

Nowadays, 40G QSFP+ transceiver modules are widely deployed in optical network with various advantages, such as delivering excellent high speed optical/electrical performance coupled with low power dissipation. Using bundled fiber cables and MPO connectors, the port density of QSFP+ is triple that of SFP+. Moreover, the power consumption is reduced from 1000 mW maximum per lane for SFP+ to 375 mW maximum per lane for QSFP+. In order to further expand the portfolio of innovative parallel fiber op...

40GBASE LR4 QSFP Transceiver Links: CWDM and PSM

As we all know, 40GBASE SR4 QSFP+ transceivers usually use a parallel multimode fiber (MMF) link to achieve 40G. It offers 4 independent transmit and receive channels, each capable of 10G operation for an aggregate data rate of 40G over 100 meters of OM3 MMF or 150 meters of OM4 MMF. However, for 40GBASE LR4 QSFP+ transceivers, there are two types of links. One is coarse wavelength division multiplexing (CWDM) and the other is parallel single-mode fiber (PSM). What’s the difference between QSFP ...

FS.COM 40G QSFP+ Module And QSFP+ Cable Installation Guide

Currently, a data transfer rate of 40 Gb/s between a switch and a server in the rack is becoming predominant since 10Gb/s can no longer satisfy us. 40G QSFP+ module and high speed QSFP+ DAC cable are mainly used as media to support high transfer rates between these devices in the rack. However, the inappropriate use of them such as improper installation and removal will exert a negative impact on performance. This article will serve as an operational guidance.

CFP Module Overview: CFP, CFP2, CFP4 & CFP8

According to the report of IHS Infonetics, 100G will make up over 50% of data center optical transceiver transmission capacity by 2019. CFP/CFP2/CFP4 and QSFP28 are main components of 100G optical module market. 100G CFP transceiver module emerges earlier than 100G QSFP28 transceiver, but it is now gradually replaced by QSFP28. As the basic principles of optical modules remain the same, we can still learn from CFP transceiver module to understand 100G optical module. This article would touch the...
