    GIGALIGHT’s 400G QSFP-DD 2XFR4 Optical Module Offers a New Option for 400G Data Centers

    [Shenzhen, China, September 13, 2023] Pursuing the optimal 400G data center configuration has always been a hot topic and focus in the industry. GIGALIGHT recently announced the launch of a 400G QSFP-DD 2×FR4 data center optical module based on the 50G PAM4 DML technology platform, providing a new option for customers’ data center architectures.

    The key difference between the newly launched 400G QSFP-DD 2×FR4 and the previous 400G QSFP-DD FR4 lies in the fact that the 400G 2×FR4 optical port supports 8×50G PAM4, while the 400G FR4 optical port supports 4×100G PAM4. Additionally, the 400G QSFP-DD 2×FR4 has networking advantages. It uses Duplex Dual LC optical interfaces, supporting the fan-out of two 200G QSFP56 optical modules, enabling a direct transition from 200G data centers to 400G data centers.

    The networking architecture is as follows:

    Furthermore, the 400G QSFP-DD 2×FR4, utilizing the 50G PAM4 DML technology platform, also has advantages in terms of cost structure and power consumption. Its main optoelectronic characteristics are as follows.

    Eye diagram and sensitivity indicators:

    • TDECQ per channel is less than the protocol specification of 3.1dB.
    • RxSens (OMA) sensitivity is better than -5.5dBm @ 2.4e-4 Pre-FEC 26.5625GBd PAM4.
    • Maximum power consumption of the optical module is less than 9W.

    With the maturity of DML technology, cost-effective 400G data center solutions are moving towards maturity and commercialization. Leveraging the fusion of existing 7nm DSP technology and DML technology enables more efficient and cost-effective processing, transmission, and reception of data. This helps reduce the unit bit power consumption, making data centers more energy-efficient and cost-effective. GIGALIGHT will continue to delve into research and development, providing customers with even better internal data center interconnection solutions.

    GIGALIGHT to Unveil Innovative 48G SDI Optical Interconnect Solution at IBC 2023 in Amsterdam

    [Shenzhen, China, September 13, 2023] The IBC event is scheduled to take place from September 15th to 18th at the RAI Amsterdam Convention Center. GIGALIGHT, the open optical network device explorer, will be introducing its second-generation mini 48G-SDI (4X12G) broadcast-grade video optical transceiver kit solution at booth 5.B55 (Amsterdam). We extend a warm invitation to our industry colleagues to join us.

    In today’s world, 8K represents the pinnacle of television standards, and it’s recognized as the “key technology” for dominating the media landscape. Achieving a 12-bit color depth at 8K resolution is a monumental challenge for manufacturers. It not only demands rigorous adherence to HDR standards but also necessitates a significant jump in near-field transmission bandwidth, from 18G to 48G.

    GIGALIGHT’s revolutionary 48G-SDI (4×12G) broadcast-grade video optical transceiver kit solution ingeniously integrates four optical extenders and four 12G SDI optical modules with a wavelength division multiplexer into a single package. This enables an all-in-one application that can transmit four uncompressed 12G-SDI signals over a remarkable 20km span of single-mode optical fiber. This empowers users with the ability to deploy uncompressed 8K SDI baseband optical connections over extended distances swiftly. Our solution finds applications in various dynamic settings, including broadcast television stations, outdoor sports events, large-scale live stage productions, outdoor live broadcasts, and more.
