Three Trends to Drive 100G Ethernet Development

The Ethernet market has seen tremendous growth over the past few years. Accelerating the transmission speed and expanding the capacity of the data center will help promote this trend. According to the IHS Infonetics report, by 2019, 100 Gigabits per second 100G Ethernet will account for more than 50% of the data center fiber transceiver market. As 100G chips are being put into production, the market for 100G Ethernet is accelerating. In this article Gigalight will analyze the three major trends driving the development of the 100G Ethernet market.

1. Data Center Architecture and Traffic Changes

At present, the transmission technology of the optical fiber industry reaches gigabits per second (10G) and 40 gigabits per second (40G), which has been a long time. These technologies are effective and most people have no objection to this. For most users, the 40G transmission speed is more than enough. The problem of data transmission in the data center becomes obvious. The scale and traffic of Internet content providers and companies on cloud data will continue to grow.

Cisco Systems predicts that global data center Internet Protocol (IP) traffic will grow at a 31% annual rate over the next five years. Changes in the way people use the Internet have contributed to this growth. The amount of data in cloud computing is getting larger and larger, and more and more data are being accessed by mobile devices in the world to access video social media content.

The construction of data centers is increasing, which requires a better data management solution. Influx of traffic has led to changes in the way three-tier networks and other ways of changing the flow of information through the data center (that is, the user interface, data processor, and database management system combined). Newer technologies allow parallel processing and can transfer more data. The Internet is becoming more and more complex and websites need more interconnections. The architecture of the data center is changing, focusing more on integrating nodes and increasing bandwidth speed. It is clear that 100G will become the new standard for higher bandwidth and smarter data center architectures.

2. 10G Can't Meet the Growing Demand for Corporate Networks

Some large data centers have switched. The Howard Hughes Medical Institute recently switched to 100G technologies, delivered through the Brocade MLXE router. The data center includes 56 11G ports, all equipped, and its efficiency has reached the highest priority of the switch. Traditionally, data centers will rely on 10G multi-beam transmissions that require link aggregation and lead to sub-optimal and inefficient load balancing.

This is where 100G comes into play. It frees up space, minimizes data aggregation, and significantly increases overall efficiency. As companies continue to grow in size and data needs become more complex, 100G will provide them with the bandwidth speed and efficiency they desperately need. Companies with four or five 10G ports have witnessed their database growth and may find switching to more affordable and scalable 100G ports. Of course, this is driven by costs and the resources of the company.

3. The Continuous Development of CMOS Technology Will Make 100G Become Mainstreams

With the evolution of 10G technology, before 100G technology becomes mainstream, which requires a certain amount of time to develop transceiver technology. When it is adopted, it is expensive and requires a lot of power. Over time, advances in chip technology have reduced more costs and various energy-saving technologies have emerged. This is exactly the reason that 100G technologies wins in the market, and the adoption of CMOS technology makes it an industry standard. Because using CMOS architecture will make it faster and use less power at the same time.

Once the technology is mature, the 100G system architecture can save more power and provide up to 10 times the speed. Currently, Cisco and Brocade Communications Systems sell 100G switches and routers at the enterprise level. However, the average cost per port of the switch is 2,500 US dollars, which means that companies using 100G networks will have to pay a lot of money. However, with the development of CMOS technology, creating these systems will become easier and more economical. These systems will reduce costs, reduce data center size and power requirements, and make 100G applications mainstream.

CSFP (Compact SFP): How Much Do You Know

Compact SFP is a new kind of fiber transceiver usually known as CSFP fiber optic transceivers. CSFP is short for Compact SFP. CSFP has the same size of SFP, Cisco also called this as 2- channel bi-directional SFP. And in this post, we will guide you have a deeper understanding about Compact SFP if you are interested. 

Introduce CSFP MSA and CSFF MSA:

The CSFP MSA defines a transceiver mechanical form-factor with latching mechanism and a host board, SFP-like, electrical edge connector and cage. The CSFF MSA also defines a transceiver mechanical form-factor. The Dual-Channel CSFP has the same mechanical dimensions as the industry standard SFP transceiver and is compatible with the standard SFP cage. The Single-Channel CSFP and CSFF are half the size of the industry standard SFP and SFF packages. The CSFF design is modular to enable configurations of integrated 1, 2 or 4 channel modules. These highly integrated compact transceiver modules will enable network system vendors to increase port density and data throughput, while reducing network equipment cost. Gigalight CSFP transceivers are compatible with the Compact Small Form- Factor Pluggable (CSFP) Multi-Source Agreement (MSA).

What Is CSFP?

CSFP (Compact Small Form Factor Pluggable) is a Compact SFP, which develops a more advanced and compact CSFP package based on the current popular SFP package. By adopting dual channel, the design of the four channels, CSFP uses the existing SFP common interface, but reducing the overall dimensions of existing half of the industry standard and a quarter. By combining channel number, it can also be flexible configuration. If the traditional discrete element scheme is continued, it will be difficult to achieve the above functions in technology. CSFP combines with high integration of optoelectronic integrated technology, on the basis of all the technical advantages of a SFP, greatly decreasing the size of the shape of the optical transceiver modules and optical system, a significant increase in density of communication port and data throughput, reduce the system cost. It is expected to play a prominent role in the data communications market. CSFP has 155M, 1.25G and 2.5G in speed.

When Compact SFP (CSFP) is used?

Most commonly CSFP is used in Central Office/Aggregation site operating at Tx1&Tx2:1490nm Rx1&Rx2:1310nm and it get’s connected to 2 CPE sites which have simple BiDi SFP operating in Tx:1310nm Rx:1490 at each site. Compact SFP (CSFP) major application is to use it in FTTx scenario where we have (point-to-point) connections from Central Office/Aggregation Site to (CPE) Customer Premises Equipment. CSFP can help us double the Central Office/Aggregation Site port density (we can achieve 2xGE from one aggregation site port) and as well reduce power consumption in Central Office as we use 2 times fewer ports.

How about Gigalight CSFP Transceiver?
