400G ZR & ZR+ – New Generation of Solutions for Longer-reach Optical Communications
400G ZR and ZR+ coherent pluggable optics have become new solutions for high-density networks with data rates from 100G to 400G featuring low power and small space. Let’s see how the latest generation of 400G ZR and 400G ZR+ optics extends the economic benefits to meet the requirements of network operators, maximizes fiber utilization, and […]
400G OSFP Transceiver Types Overview
OSFP stands for Octal Small Form-factor Pluggable, which consists of 8 electrical lanes, running at 50Gb/s each, for a total of the bandwidth of 400Gb/s. This post will give an introduction of 400G OSFP transceiver types, the fiber connections, and some QAs about OSFP. 400G OSFP Transceiver Types Below lists some current main 400G OSFP transceiver types: […]
Four Types of 100G QSFP28 Transceivers Overview
For 100G optical transceivers, there are a number of form factors including CFP/CFP2/CFP4, CXP and QSFP28. Among these different 100G form factors, it appears that the market has chosen QSFP28 as the primary form factor for 100G links. Hence, this post will focus on several types of 100G QSFP28 transceivers—100GBASE-SR4 QSFP28 transceiver, 100GBASE-PSM4 QSFP28 transceiver, […]
QSFP28 – A Better Way to 100G
The battle over 100G component market has been upgraded with the emerging of 100G QSFP28 module—an optical transceiver which can support 100G with the transmission mode of 4*25G. Before its appearance, the way to move to 100G is considered to be 10G→40G→100G. However, the new 100G road map with QSFP28 is 10G→25G→100G or 10G→25G→50G→100G. Currently […]
When Should Use GBIC or SFP ?
In computer industry, technology undergoes rapid progress for data transmission at high speed. Defined by the IEEE 802.3-2008 standard, gigabit Ethernet just achieved this performance by using various fiber optical products, including GBIC and SFP transceiver modules. GBIC vs. SFP: this post will discuss when we use these two kinds of transceivers. GBIC Transceivers A […]
