As the internal traffic of the Internet giant's data center increases nearly 100% every year, many giants will seek 200G optical module to solve the growing demand for data transmission. There are mainly two types of 200G optical modules: QSFP-DD and QSFP56. Among them, QSFP-DD refers to four channel small pluggable double density package, which is defined by QSFP-DD MSA group, which is twice the density of QSFP28 or QSFP56. There are eight channels, and the speed of each channel is as high as 25G or 50G, so it supports 200G or 400G optical transmission.

The 200G QSFP-DD SR8 optical module is a solution for short distance multi-channel interconnection of 200G data center. Its optical interface is 24 core MPO interface, the center wavelength is 850nm, and supports 8-channel 25Gb/s data channels. Each channel can transmit 70m with OM3 or 100m with OM4.

Features:

Ø Using hot pluggable qsfp-dd package form

Ø 8-channel full duplex transceiver module

Ø 8-channel 850nm VCSEL laser array and PIN photodetector array

Ø CDR circuit is built into the receiving and transmitting channels

Ø It meets QSFP-DD MSA and IEEE 802.3bm 100GBASE-SR4 Ethernet standard

Ø Compatible with Infiniband DDR/EDR standard

Ø Maximum rate up to 206.25Gbps（8x25G NRZ）

Ø The maximum transmission distance can reach 70m or 100m through OM3 or OM4 multimode fiber

Ø The maximum power consumption is less than 4W

Ø MPO 24 optical ports

Ø Operating temperature ranges: 0℃ to 70℃

Ø Supply voltage 3.3V

Ø Comply with ROHS environmental standard (lead-free)

The 200G QSFP-DD SR8 is a high performance optical module, which is mainly used for short distance multi-channel data communication interconnection applications. It integrates eight data channels with a bandwidth of 8x25.78125Gbps. The advantage of 200G QSFP-DD is that the 1U panel can achieve the density of 36*200G/400G, and is compatible with QSFP forward and backward, and compatible with existing QSFP28 optical modules and AOC / DAC direct attach cables.

From the current market demand, the demand for data center products is promising. This requires continuous product upgrading, while reducing product costs. With its own technical advantages and unique insight, the 200G QSFP DD SR8 optical module launched by ETU-LINK is precisely built to solve the cost problem for customers.
