What is PAM4? PAM4 is short of pulse amplitude modulation 4. It is a modulation technology that uses four different signal levels for signal transmission. it with an additional two levels compared with the NRZ (non-return to zero) modulation. This means that, under the same baud rate, the bit rate of PAM4 signals is twice […]
The QSFP-DD800 optical transceivers introduce 8x100G and 2x400GGBASE Quad Small Form-Factor Pluggable Double-Density (QSFP-DD) modules, it offering customers super-high-density pluggable transceivers compared with 800G OSFP along with the flexibility of 400 Gigabit Ethernet and 100 Gigabit Ethernet connectivity options for data centers, high-performance computing networks, enterprise core and distribution layers, and service provider applications. The […]
Introduction 100G Single Lambda transceivers were defined by 100G Lambda MSA (100G Lambda Multi-Source Agreement). The MSA 100G MSA uses 100G PAM4 optical signaling and encoding it is able to use 100Gb/s per channel to transmit from 2m up to 40KM via single-mode fiber. Advantages The traditional 100Gb/s optical standards such as 100GBASE LR4, 100GBASE […]
CS Connector is developed by Senko Advanced Components, and the CS is widely considered to be the best option of the three. This CS Connector design utilizes the tried-and-true standard 1.25mm LC form factor ferrule, but with tighter spacing between the ferrules. With the CS design, pitch is reduced to 3.8mm from the LC standard […]
Category 8 offers four times the bandwidth of Category 6A cabling, with internal impairments specified up to 2GHz; alien impairments are also specified up to 2GHz. Structured Cabling Components If shielding and length limitations are put aside, Category 8 is fundamentally the same cabling system as prior categories; it is simply made to perform at […]
The Cisco® 40GBASE QSFP (Quad Small Form-Factor Pluggable) portfolio offers customers a wide variety of high-density and low-power 40 Gigabit Ethernet connectivity options for data center, high-performance computing networks, enterprise core and distribution layers, and service provider applications. Features and Benefits of Cisco QSFP Modules Hot-swappable input/output device that plugs into a 40 Gigabit Ethernet […]
Since twisted pair used in the data communication network, there are many types of terminology like UTP, STP, FTP etc for describing the twisted cable, these cables are used in the different environment like the high-performance data center, enterprise machine room, manufacturing facilities etc. Based on ISO/IEC 11801, there are 8 types of cables, please […]
The broad advantages of structured cabling over point to point cabling (such as that used on top of rack configurations in a data center) are seen as: improved energy efficiency increased switch port utilization quicker system adaption greater scalability easier network expansion less maintenance and administration less expensive switches overall lower cost of ownership. […]
As networking equipment becomes denser and port counts in the data center increase to hundreds and thousands of ports, managing cables connected to these devices become a difficult challenge. Traditionally, connecting cables directly to individual ports on low port-count equipment was considered manageable. Applying the same principles to high port-count equipment made the task more […]
SWDM4 is a new technology to support 100G over MMF (multimode fiber. Currently, there are only proprietary solutions without a MSA but this may change as commercialization continues. SWDM4 uses a complex shortwave wavelength division multiplex (SWDM) technology. Light at four different wavelengths (850, 880, 910 and 940 nm) are transmitted in a multi-mode fashion […]
