Since the internal flow of Internet giant data centers close to 100% annual growth rate, many data center deployment earlier Internet giant, will seek to acquire 200G as soon as possible, but there are many companies choose to skip 200G 400G wait to get a better price. The 400G Ethernet standards from IEEE have completed at 200G Ethernet standard, it reflects the mentality of most of the industry's enterprises - more optimistic about 400G.
The market is expected in 2020 200G and 400G are commercially ready, but will be more mainstream 400G, better cost. But as the transition 100G to 400G, 200G optical module has its irreplaceable role. About 200G QSFP-DD SR8, you know how much? 200G optical modules to solve the long-distance, high-speed, small size and low power consumption are the main trend of the future development of optical modules, 200G optical modules mainly for the data center market, transmission distance up to 2km, but also to upgrade the transmission distance further extended to 10km.
200G optical module mainly QSFP-DD and QSFP56 package, 200G QSFP-DD SR8 wherein the optical module is a high performance module for short-range data communication, and multi-channel interconnect applications, supporting 8 25Gb / s data channel. Each transport channel may be used OM3 or OM4 transport 70m 100m. The product provides a new generation of solutions for low cost, low power, high density, high speed of the data center. Excellent thermal design reduces the temperature problems, low power consumption, the power consumption is less than 4W, support the digital diagnostic functions, fully meet the zero errors 100m OM4 fiber transmission applications.
200G QSFP-DD-SR8 specific parameters:
- The use of hot-pluggable package QSFP-DD
- 8-channel full-duplex transceiver module
- 8-channel laser arrays 850nm VCSEL and PIN photodetector array
- Receive and transmit channel circuit built-in CDR
- In line with QSFP-DD MSA and IEEE 802.3bm 100GBASE-SR4 Ethernet standard
- Compatible with InfiniBand DDR / EDR standard
- The maximum rate of up to 206.25Gbps (8-way 25G NRZ)
- Through the multimode fiber (MMF) up to 70 m (OM3) or 100 m (OM4) transmission distance
- Maximum power consumption is less than 4W
- MPO24 optical port
- Operating temperature range from 0 to 70 degrees Celsius
- 3.3V supply
- Comply with RoHS environmental standards (unleaded)
200G QSFPDD SR8 optical module using the lens design and integration of independent two optical engines since the inquiry, in the same size package QSFP +, 8 duplex data channel has to 25Gbps, bandwidth is twice the original 100GEQSFP28 SR4 density doubling the rapid growth of optical QSFP DD module can greatly satisfy the data center traffic.
200G QSFP-DD advantages:
QSFP-DD advantage is that the density can be done 1U panel 36 * 200G / 400G, and the pair of front and rear QSFP to backward compatibility, a conventional compatible optical module QSFP28 and AOC / DAC high-speed cable or the like.
Small Form Factor Pluggable SFP-DD automatic double-density optical module package, more than double the bandwidth SFP56 SFP28 or (25G / 50G), supporting higher rate (50G / 100G) while also maintaining backwards compatibility SFP28 or SFP56. QSFP-DD Quad double density packaging SFP optical module, defined by QSFP-DD MSA group, or QSFP56 QSFP28 density than doubled, eight channels, each with a rate of up to 25G or 50G, 200G or support so 400G optical transmission.
In addition to the ability to provide higher bandwidth density and higher bandwidth density, advantages 200G QSFP-DD optical module may be further characterized by the front of the QSFP be backwards compatible with, the conventional compatible optical module QSFP28 and AOC / DAC like.
From the current market demands, data center offerings strong demand prospects. This requires ongoing product upgrades, while reducing product costs, 200G QSFP DD SR8 optical module is the cost for customers to solve problems and well-built.
