LightCounting expects sales of Ethernet optical transceivers will have declined by 18% when it tallies figures for 2019. The decline is the largest the market research firm has recorded and the first year-on-year dip since 2009, when sales slipped 4%. However, LightCounting states in its new “High Speed Ethernet Optics Report” that purchases of Ethernet optical transceivers should rebound through 2024.
This article explores some practical problems and difficulties in the application of high-speed transceiver in the data center. For example, the 40G / 100G high-speed transceiver has not developed a revolutionary new photoelectric conversion technology, but by upgrading the manufacturing process, the original 10G transceiver technology to expand. In essence, for the 10G transceiver, by increasing the number of transceiver fiber to enhance the bandwidth.
Transceivers are available for singlemode and multimode fiber installations. This article talks about the critical factors that influence your choice: Distance, the type of laser source, cost and speed requirements.
Several industry leaders, including Broadcom, Cisco, Finisar, Intel, Juniper Networks, Marvell, Molex and Samtec, have announced a new QSFP-DD800 MSA Group to advance the development of high-speed, double-density quad small form factor pluggable (QSFP-DD800) modules to support 800 Gbps connectivity. This MSA will enable QSFP-DD800’s eight electrical lanes to operate at 100 Gigabit per second (Gbps) each, by providing technical solutions for 800 Gbps module and connector systems. It will also define a module, connector, stacked connector and a hybrid connector that is a BiPass/Flyover variant which can eliminate the signal losses on a traditional PCB.
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.
