Integrated WDM System

Integrated WDM System

The integrated WDM System offers 1U 48X10G→480G System and 1U 12X100G→1.2T System which supports single-channel access rate up to 10 Gbit/s and adaptive access to all types of services at rates of 10 Gbit/s or lower (like FE/GE/10GE LAN, 10GE WAN, STM-1~64, etc.) and 40GE, 100GE, and other service types.

OTNS8600P integrated WDM equipment has the outstanding characteristics of large capacity, small size, low energy consumption and high performance,The equipment adopts high-density optoelectronic integration technology to avoid complex patch cords connection. It is easy to form an end-to-end complete WDM transmission scheme, which brings super large transmission capacity, perfectly matches the installation conditions of data center room, and simple management mode, which brings the ultimate user experience to DCI bearer network in metropolitan area.

Types of Data Center Interconnection System

  • 48X10G→480G System
    Based on optical integration technology, Sintai Communication Co., Ltd independently developed OTNS8600 P-type integrated wavelength division equipment, 80G, 160G, 400G, 480G transmission capacity.
  • 12X100G→1.2T System
    OTNS8600P integrated WDM equipment developed by Guangzhou Sintai Communication Co., Ltd. for the data center interconnection (DCI) scenario has the outstanding characteristics of large capacity.

Integrated WDM System Advantages

  • supports mixed transmission of multiple services, including 40GE, 100GE and other service types. The service interface and quantity can be flexibly customized by customers

  • maximum transmission capacity of 1RU is 1.2Tbps (12*100G), and the transmission capacity can be effectively extended to 2.4Tbps of 1 fiber through device stacking

  • no complex photoelectric cross with transparent transmission of services, and complete physical isolation of service ports, which improves the network security

  • supports 1+1 line protection at optical cable side, and automatically selects transmission route to improve network reliability

  • supports in band monitoring channel, and the whole network SNMP management can be realized by optical path connection

A Guide to Data Center Interconnection (DCI)

Inter-data center interconnect is the connection between two data centers or two buildings within a large data center campus. These inter-data center interconnects are typically between 10km to 80km. Industry people refer to data center interconnect as DCI.


Data center interconnect refers to the networking of two or more different data centers to achieve business or IT objectives. This interconnectivity between separate data centers enables them to work together, share resources and/or pass workloads between one another.

A data center interconnect is mainly accomplished using networking tools and techniques along with supported software and data center management processes.

Products that were only used within the data center are gaining reach, and they’re running up against coherent solutions that were formerly only used for long distances. Due to the increasing bandwidth and decreasing cost, coherent is being pulled closer into the data center.

Why Choose Sintai DCI Equipment?

SINTAI 1.6T transponder is an OTN transmission platform customized for Data Center Interconnect (DCI) applications. it represents a best-in-class alternative to Compact DCI systems by providing not just the capacity required to meet interconnection needs but also the flexibility, manageability, ease of use and cost-efficiency that make it ideal for data center interconnection. It's up to eight single wavelength 200G channels, with 8x 200G CFP2 coherent optics uplinks on the line side, and 16x 100G QSFP28 on the client side.

SINTAI 1.6T transponder is widely applicable to DCI scenarios for industries and enterprises with high digitalization, including IXPs, finance, large enterprises and etc.It also enables easy scaling of existing network capacity without replacing exiting OTN/DWDM infrastructure.

Integrated WDM System FAQs

  • Why is DWDM needed? Why is DWDM needed?
    Why is DWDM needed?

    Dense Wavelength Division Multiplexing (DWDM) has long been the technology of choice for transporting large amounts of data between sites. The main advantage is that it increases bandwidth by allowing different data streams to be sent simultaneously over a single optical fiber network.

  • Why C band is used in DWDM? Why C band is used in DWDM?
    Why C band is used in DWDM?

    The channel space of DWDM is more closeness, so choose the C-band (1530 nm-1565 nm) and L-band (1570 nm-1610 nm) transmission windows.

  • How many channels are in DWDM? How many channels are in DWDM?
    How many channels are in DWDM?

    Today's DWDM systems typically support 96 channels spaced at 0.8 nm apart within the 1550 nm C-Band spectrum. Because of this, DWDM systems can transmit a huge quantity of data through a single fiber link as they allow for many more wavelengths to be packed onto the same fiber
