GigaLight Displays a Series of Optical Transceivers of Big Data Center at OFC 2017
Gigalight is going to take a series of low-cost optical transceivers of big data center, which have already been under mass production, to participate in OFC 2017. These optical modules include 40G QSFP PSM4(10KM), 40G QSFP LR4, 100G QSFP28 SR4 , 100G QSFP28 LR4 (10KM), 100G QSFP28 PSM4 ( 2KM ), etc. Booth Number:3625

In the past year, Gigalight as the major supplier of AOC of big data center in the domestic market placed high priority on the reduction of cost and power consumption of data center 40G/100G. Gigalight has made substantial progress both in cost management and the ability of mass production, and greatly enhanced the price competitiveness through comprehensive approaches such as self-developed optical engine and IC, introduction of automatic packaging equipment and seeking strategic assistance of suppliers. Our major clients who purchased high-speed optical transceivers and AOC in 2017 can fully recognize the outcomes of our hard work. The goal of Gigalight Data Center in 2017 is to reduce the cost of optical interconnect parts, while guaranteeing the quality. Ove the past three years, the optical transceivers and AOC of Gigalight Data Center have proven we are able to achieve this goal.

Besides cloud computing and data center products, Gigalight will also display MAN 100G CFPx optical transceiver in both multimode and single mode. The biggest advantage of our CFPx lies in the compatibility of software and hardware. We will also demonstrate cloud programmer and 40G/100G CHECKER at the booth.

Gigalight released 2KM Version of 100G QSFP28 PSM4 Optical Transceiver.

      On March 9th 2017,Gigalight released 2KM application data center 100G PSM4 optical Interconnect module , which officially opened the journey of 100G data center single module product line .

      Gigalight’s QSFP28 PSM4 exhibits excellent performance under the three-temperature (-5 °C / 25 °C / 55 °C) environment, and both of the uniformity and consistency of the four-channel could meet the design specifications. All the margins under the conditions of three-temperature are over 15% while the sensitivity is superior to -9.5dbm(1E-5) that required by the agreement.

      Large data center applications require no less than 2KM fiber channel transmission, and Gigalight’s product lines mainly focused on the short range optical interconnect within 300 meters in data center before. In order to meet the needs of large-scale data center applications, Gigalight starts to focus on developing single-mode product line of data center and its packaging technology in 2015, and in the end of 2016, Gigalight officially engaged in selling 100G QSFP28 LR4 (DML) products. The success of the product of 100G PSM4 optical transceivers with 2KM has not only enriched the client application solutions, but also marked that Gigalight officially owns the key technology of single-mode optical engine.Gigalight will begin to have a mass production in Q2. Currently, sample orders are acceptable with the price of $480.
    Gigalight has a rich 100G product line:
100G CFPx Series :

The Road to 100G VCSEL Optical Transceivers From Gigalight

There are various kinds of 100G VCSEL series products in GIGALIGHT, up to February 2017; GIGALIGHT is capable of providing 100G multimode VCSEL optical transceivers with packaging technology as follows:
CFPX series: CFP SR10 , CFP SR4*, CFP2 SR10, CFP2 SR4*, CFP4 SR4
QSFP28 series:QSFP28 SR4,QSFP28 AOC
The result that GIGALIGHT is playing a pretty important role in the global optical interconnection field completely benefited from the persistence of 10 years adhering to the VCSEL technology strategy. Despite of the fact that GIGALIGHT does not produce VCSEL chips itself, close relationship between GIGALIGHT and global VCSEL chips supply chain is being strongly maintained. GIGALIGHT is patented multiple unique and mature technologies with FA, which angle is 45; fiber optic LENS, which shares the same angle with FA, and multi-mode parallel optical engine. Thanks to the years of VCSEL technology platform from 10G TO 40G, and then to 100G multi-mode parallel optical transceivers, GIGALIGHT always remains the first level in the global VCSEL optical transceivers industry.  

Regarding the 100G VCSEL series optical transceivers products, GIGALIGHT is able to provide both fully dimensional products and multiple alternatives to the customers; also, the compatibility is outstanding. Industry recognition speaking, GIGALIGHT can be regarded as the leading manufacturer of multi-mode VCSEL technology, which, as a matter of fact, only be second to FINISAR. Compared to other first-rate VCSEL optical transceivers manufacturers, the technology is about to be equally matched. The only difference rests with the advantages of low cost and expandability that GIGALIGHT possesses. When it comes to CFP equipments, the original 100G CFP SR4 & 100g CFP2 SR4 multi-mode optical transceivers with Gearbox chips installed inside that GIGALIGHT developed could solve the issue of lateral interconnection between 100G CFP old interface device and 100G BASE-SR4 new customersEasily speaking, it realizes the interconnection between the 100G SFP multi-mode interface and QSFP 28 multi-mode interface. 

Low cost: because both of the technologies of VCSEL optical transceivers and production platform are created by GIGALIGHT itself, thus, the cost of coaxial package technology and COB technology have been optimized to be close to the edge. The delivery advantage has helped GIGALIGHT winning strong support from the suppliers. Moreover, almost zero refund rate of multi-mode VCSEL products that GIGALIGHT keeps helps to lower the cost. 

Challenge & opportunity: currently, the main problem lies in the transmission bandwidth of multi-mode fiber along with the improvement of modulation rate of VCSEL, which requires other VCSEL with different features to be matched with. For example, if we adopt PAM4 to transmit signals, then the VCESEL will be needed to have a fairly wide dynamic range of modulation. For the future high-speed 200G/400G VCSEL optical transceivers, GIGALIHT’S VCSEL optical transceiver will use the same technical framework and the same technology platform, mutual penetration between platforms. By making sure that the core components of optical engines of multi-mode parallel optical transceivers will be developed toward the future 200G/400G optical transceivers modulated by PAM4, the nature of hero can still be showed.

3. Save command, writes value 0001h to address 0x91F0;
4. Read status, wait until the address 0xA004 = 0004h(save success), and then read the address again 
0xA004 = 0000h(Idle, read twice to ensure status is cleared).
Normally saving needs about 1 second, but the longest time is about 4 seconds, we suggest customer can read 0xA004 after waiting for a while.
