High-speed transceiver parallel optics MT subassembly

 With the growth of global data volume, parallel optical technology is an important technical for the expansion of current data centers, and the optical transmission rate has continuously evolved from 10Gbps, 40Gbps, 100Gbps to 200Gbps, 400Gbps, and even 600Gbps, 800Gbps. At this year's OFC conference, a number of Chinese suppliers have successively demonstrated 800G rate optical modules, which means that 800G will enter a new era.

What is parallel optics? Parallel optical technology is a special optical communication technology that transmits and receives signals at both ends of the link. Parallel optical transceiver modules are usually used to achieve high-speed signal transmission at both ends. Parallel optical technology is a cost-effective solution for 4×50G, 8×50Gbps transmission.

In parallel optical signal transmission, the parallel optical modules at both ends of the link contain multiple transmitters and receivers. Multiple optical fibers are used to transmit and receive signals. The data rate of multiple-channels parallel transmission can support 40G to 100G per second. As shown in the figure, 8-bit data is simultaneously transmitted through parallel lines, so that the data transmission speed is greatly improved. Multimode parallel technology is mostly used for short-distance transmission of 100G and below.

 

Parallel optical modules rely more on high integration and small packaging to generate less heat than multiple discrete devices. MT (MPO) ferrules and optical subassemblies are one of the key components supporting parallel optical interconnects, which are used to connect internal optical lenses and external optical interfaces, and can be integrated into optical module boards. The small size and multi-channel of the MT ferrule makes it easy to use as an external optical interface in the parallel transmission.

Relying on high-density parallel optics design and manufacturing capabilities, as well as high-precision mold manufacturing and measurement technology capabilities, HYC now has the mass production capacity of high-speed transceiver optical subassemblies.

MT-Jumper

The ferrules of MT-jumper are available in 0° and 8° polishing angles. The length tolerance can be customized, and the minimum can meet ±0.15mm.

 

MT-2×Mini MT

Due to the compact internal structure of some optical modules, the traditional MT ferrule is bulky and may not be able to be inserted into the transceiver. Mini MT ferrules are the right devices to use in this small space connection, which are half the size of traditional MT ferrules.

 

MT-FA

MT-FA is a short fiber jumper composed of MT and fiber array. The end face angle of FA can be customized and it requires high precision. It is widely used in 100G PSM4 to connect to the external port.

Synergy Research： Hyperscale Data Center Count Jumps to 430

New data from Synergy Research Group shows that the number of large data centers operated by hyperscale providers rose by 11% in 2018 to reach 430 by year end. The US still accounts for 40% of the major cloud and internet data center sites.

Among the hyperscale operators, Amazon and Google opened the most new data centers in 2018, together accounting for over half of the total. The companies with the broadest data center footprint are the leading cloud providers – Amazon, Microsoft, Google and IBM. Each has 55 or more data center locations with at least three in each of the four regions – North America, APAC, EMEA and Latin America.

“Hyperscale growth goes on unabated, with company revenues growing by an average 24% per year and their capex growing by over 40% – much of which is going into building and equipping data centers,” said John Dinsdale, a Chief Analyst and Research Director at Synergy Research Group. “In addition to the 430 current hyperscale data centers we have visibility of a further 132 that are at various stages of planning or building. There is no end in sight to the data center building boom.”

High Density Solution - LC Uniboot Connector

With the increasing demand for data center and bandwidth, effective cable management is a real issue. How to build more optical fiber cables in limited space is becoming a challenge for data center managers.

For data center managers, convenient management and space saving are really important in high-density cabling. LC Uniboot connector is especially designed and manufactured for better airflow and cable management in high density applications.What are the benefits of LC Uniboot connector?

Compact design to save space
Combining two fibers into a single jacket can save up to half the patching cable space compared to traditional LC duplex fiber patch cords.

Push-pull tab design
For data center administrators, it can be challenged to insert and disconnect patch cords especially in a high density environment. The push-pull tab design of LC Uniboot connector makes for easy removal of the assembly without disturbing the neighbouring ports, which offers maximum accessibility in high-density installations. With this design, the technician is able to finish the installing and removing procedures with only one hand and no additional tool are needed. What’s more, half-surround tab end avoid the cable ganged each other.

Easy Polarity Revisable
The traditional LC connector uses two jumper independent connections. If you want to change the polarity of the transmission and reception, you need to change the entire wiring system. It is difficult to do that and prone to failure. The uniboot option includes a reversing polarity feature that provides quick and easy polarity changes in the field. Polarity changes can be made in the field quickly, without the use of tools, to the correct fiber mapping polarity.

The compact design and easy polarity reversible function of the LC Uniboot Connector makes managing cable systems simpler.
