This innovative solution is built around a white box design.

Key System Features:

Capacity and Form Factor

  • A 2U standalone chassis can support a maximum capacity of 6.4T, with options for 1U and 2U chassis.

Use Cases

  • Primarily designed for Data Center Interconnect (DCI) and metro network WDM/backbone WDM, providing a white box transmission platform.

Design Advantages:

  • The product emphasizes white box design and simplified architecture.
  • A hybrid design of optical and electrical layers effectively saves data center space and facilitates bandwidth expansion.
  • Supports SNMP-based graphical management interface for intuitive fault localization.

Cooling and Redundancy

  • Utilizes a front-to-rear airflow design, combined with multiple sets of high-speed redundant fans and power supplies, ensuring outstanding cooling performance.

Hardware Support

  • Optical Layer: Supports Raman, EDFA, WSS, and OP cards, among others.
  • Electrical Layer: Line-side supports 100G/200G/400G coherent cards, while client-side supports 10GE/25GE/100GE/400GE.

Network Management

  • Supports SNMP/Netconf protocols, CLI/Web/BS management, dual main control backup, and OSC communication.
  • Boasts robust transmission and network management capabilities, making it especially suitable for data center DCI and metropolitan network applications.

Business Cards

400G QSFP-DD DCO Muxponder

This is the first business card introduced by GIGALIGHT in China. The line-side port supports cost-effective 400G QSFP-DD DCO ZR/ZR+, while the customer side supports 4x100GE QSFP28 ports, meeting the needs of DCI interconnect scenario applications.

800G Transponder 1/4 Business Card

With up to 800G Bandwidth, featuring support for two 400G CFP2 DCO on the line side and 2x400G QSFP-DD ports on the customer side, catering to high-bandwidth DCI applications.

400G QSFP-DD DCO ZR+ Coherent Module

Supports single-wavelength 400G DWDM, adjustable Tx optical power from 0 to -6dBm, flexible grid, and openZR+ protocol. It utilizes OFEC, offers excellent interoperability, achieves an Rx OSNR of 24dB/0.1nm @ 400G 16QAM, meets the requirements for 300km to 400km service interconnections, and has a typical power consumption of less than 22W.

GIGALIGHT is one of the OpenZR+ members. The company boasts significant technical expertise in the coherent optical module field.
