A SFP (Small Form-Factor Pluggable) transceiver is a compact, hot-swappable device that can be used for both transmit and receive data and also plugs into a physical port of a network device. It is used in the communication network and has a transmitting side and receiving side. The SFP transceiver has a laser which communicates with the receiving side of the other optic on the other side. SFP transceivers are designed to support several communication standards including SONET, Gigabit Ethernet and Fibre Channel, and their interfaces on a networking device such as a router provides a modular device that can be freely adjusted to fiber optic and copper networking specifications.
While once cost prohibitive, 100G network upgrades are now a viable option to improve network performance. The emergence of the QSFP form factor has brought economies of scale to 100G upgrades, putting 100G within the cost reach of both small and hyper-scale data center operators. With a small profile and reduced power consumption, the QSFP form factor is the choice of switch manufacturers for 100G platforms.
The Internet of Things (IoT) is at the beginning of its golden age. Forecasts note that the number of connected devices could exceed the 20-billion mark by next year and could reach 50 billion by 2022. For all this, we are basically using just one network protocol. The still-dominant IPv4 standard uses 32-bit addresses, only making around 232, or 4.3 billion different addresses possible. Luckily, a new 128-bit format has existed in principle since 1998. This IPv6 standard offers an address space of 2128, or around 340 sextillions, eliminating any concerns. However, DE-CIX measurements show that currently, only around 5 percent of traffic corresponds to the new standard.
400ZR pluggable coherent transceivers for up to 80-120km distance will emerge in 2020~2021 time frame, and their cost is expected to be comparable to today’s 80km 100G pluggable PAM4 transceivers, which results in essentially 3~4x cost per bit reduction.
The more data center managers know about extending the life of their equipment and infrastructure, the better prepared they’ll be to influence the procurement process and take advantage of funds that do become available. Two tactics to consider are: Dark fiber. Many ISPs installed more fiber than was initially needed and dark fiber can be activated and leased; and extend the life of existing fiber optic connections by upgrading termination equipment.
Adesto’s FT 6050 Smart Transceiver system-on-chip (SoC) now natively supports LON®, LON/IP, BACnet/IP, and BACnet MS/TP protocol stacks. This capability will help modernize and simplify automation and control networks, especially in smart buildings. Its open systems approach allows BACnet workstations and LON network manager and integrator tools to natively field-configure, provision, and monitor controllers as either LON or BACnet devices, or both.
Fluke’s CableIQ Qualification Tester helps you determine whether the cable you’re using will work properly and provide the bandwidth needed for your application, troubleshooting and qualifying Ethernet cabling speed (10/100/1000 VoIP).
The TIA has introduced a certification program to ensure that data center facilities conform with the specifications in its ANSI/TIA-942 standard series. TIA will work with Certac to provide verifications of conformance to standards by independent conformity assessment bodies (CABs) that can verify data center conformity with the standards.
A new report from the Dell’Oro Group says demand for 100-Gbps Ethernet switch ports will peak next year. While demand for such ports will continue to be strong, composing more than 30% of the market over the next five years, the same timeframe will see the rise of 400-Gbps ports. Shipments of 400G switch ports will exceed 15 million, the market research firm predicts in its most recent “Ethernet Switch – Data Center Five Year Forecast Report.”
Smartoptics’ new line of optical transceivers and open line system for use in 32G Fibre Channel storage area networks complement the company’s existing line of 8G and 16G Fibre Channel products.The 32G Fibre Channel optical transceivers are available in the SFP28 form factor for use in the platforms of a variety of switch vendors. The optical modules can be used with passive filters as well as Smartoptics’ active open line systems to support reaches up to 80 km between data centers.
