The Application of DCI BOX /DCI Equipment


What is the Difference Between DCI BOX and Traditional WDM/OTN Equipment?


DCI-BOX, China Unicom calls it modular WDM equipment, and China Telecom calls it box-type WDM equipment DCI-BOX, which is a data center point-to-point interconnection (DCI) device. Before the appearance of DCI BOX, DCI usually used WDM/OTN equipment for interconnection, so what is the difference between the two?

The key distinction between DCI BOX and WDM/OTN equipment becomes apparent when we devide into their specific characteristics. Firstly, the DCI BOX is all about being compact and refined, Secondly, WDM/OTN equipment takes on a larger and more comprehensive role. This divergence is most evident when we closely consider the following aspects:

Equipment Appearance

The WDM equipment is a dedicated cabinet and a sub-frame. The height of the sub-frame is more than 12U. The capacity is expanded by inserting boards in the sub-frame, and the sub-frames are stacked after the slots of the sub-frame are full.

The DCI BOX device is fashioned to fit the standard dimensions of a data center cabinet from 1 to 2U,which is to be expanded through device stacking .

System Capacity

In the realm of DCI BOX, the frame (measuring 1 to 2U in height) packs a formidable access capacity, surpassing the 1.6T mark. Within this, each individual channel boasts a robust rate exceeding 200G.

It can realize a single-fiber 48/96 wave system wave system by stacking multiple devices. For added convenience, the client-side port effortlessly handles both 100GE and 10GE connections.

In WDM equipment, the general 12U high OTN sub-frame has an access capacity of up to 5.6T, a single channel rate supports 100G/200G/400G, the system supports single fiber 48/96 waves, and the client side supports multiple mode rate interfaces.

Equipment capacity

At present, the DCI BOX is only for point-to-point networking scenarios.

However, the WDM technology steps ahead by offering a broader spectrum of networking possibilities: ranging from point-to-point and point-to-multipoint, and morely ,multipoint-to-multipoint configurations.

In terms of data rates, the DCI BOX often used for a higher bit rate, offers an excellent fit for medium and shorter distance transmissions.

However, if your needs lean toward ultra-long-distance transmission, WDM is the champion.

 The layout of the DCI BOX service board takes the form of TMUX, which is distinct from the more complex OTN electrical cross-connect structure seen in WDM systems.

Scene Adaptation

DCI BOX equipment is suitable for DC equipment room and operator’s traditional transmission equipment room, providing 220V AC, high-voltage DC, -48V DC, these three power supply options, usually the heat dissipation mode of forward air and rear air; WDM equipment is not suitable In the DC machine room scenario, the equipment only uses -48V DC power supply, and the heat dissipation modes of each manufacturer are different, and there is rarely forward air and rear air.

Equipment Structure

The service boards,the optical amplifiers,and the multiplexer/demultiplexer, power supply, and fan of the DCI BOX equipment adopt a modular design, which is easier to maintain and replace than WDM.

Device Power Consumption

The corresponding power consumption per 100G capacity of DCI BOX equipment is basically less than 30W, while that of WDM equipment is greater than 100W.

The main difference comparison list is as follows:

What is the Difference Between DCI BOX and Traditional WDMOTN Equipment

DCI BOX and general WDM/OTN comparison table In general, DCI BOX equipment reduces transmission capacity requirements, reduces some WDM functions, adds function adaptation to DC scenarios, and modularizes equipment functions to facilitate the construction and integration of transmission systems. Later expansion is easier and more convenient.


DCI BOX in optical communication

DCI (Data Center Interconnect) is a technology and solution for connection and communication between data centers.

With the popularity of cloud computing, big data and virtualization technologies, traffic between data centers continues to grow, requiring efficient, low-latency and high-bandwidth connectivity solutions.

DCI BOX refers to hardware equipment customized for DCI needs. Their application in optical communications is mainly reflected in the following aspects:

1. High-bandwidth transmission:

 As the amount of data continues to grow, data centers require higher-bandwidth interconnections. DCI BOX usually supports high-speed optical communication technologies, such as 100G, 200G, 400G, etc.

2. Low latency:

For certain applications, such as financial trading and real-time analysis, low latency is key. DCI BOX is designed to minimize transmission and switching delays.

3. Simplified operations:

DCI BOX are typically purpose-built solutions that are easier to configure and manage than traditional general-purpose network devices.

4. Optical fiber optimization:

For long-distance and ultra-long-distance connections, DCI BOX can optimize optical signals to support longer transmission distances and reduce signal attenuation.

5. Encryption capabilities:

Data may be vulnerable to eavesdropping or attacks as it travels between data centers. To increase security, some DCI BOX provide data encryption at the transport level.

6. Flexible connection:

DCI BOX supports multiple connection methods, including point-to-point, point-to-multipoint and mesh connections, to meet different application needs.

7. Compatibility with existing networks:

DCI BOX is designed to be compatible with existing optical transmission networks and IP/MPLS networks, allowing data centers to be easily integrated with existing networks.

In summary, DCI BOX provides efficient, reliable and secure connection solutions between data centers in optical communications.

What components are needed for the DCI BOX 400G single-fiber bidirectional transmission solution?

DCI BOX 400G single fiber bidirectional transmission solution involves high data rate and single fiber bidirectional (or duplex) transmission. To support such a requirement, here are some of the main components that may be needed:

1. 400G Transceivers:

High-speed transceivers are used to send and receive data over optical fibers.

2. MUX/DEMUX (Multiplexer/Demultiplexer):

Used to separate and combine multiple wavelengths on one optical fiber so that a single fiber can transmit in both directions.

3. Optical Amplifiers:

For example, EDFA (Erbium Doped Fiber Amplifier) is used to amplify signals that are attenuated during transmission.

4. Optical Dispersion Compensation Module (ODCM, Optical Dispersion Compensation Module):

used to compensate for dispersion problems that may occur in long-distance transmission of optical signals.

5. Optical Switch:

Used to guide the path of optical signals or switch paths when needed.

6. Optical Isolator:

Used to ensure that light only propagates in one direction to prevent reverse reflection.

7. Optical Attenuator:

Used to adjust the intensity of the optical signal to ensure that the receiver is not overloaded.

8. FEC (Forward Error Correction) function:

 In order to ensure high data rate transmission quality, FEC is very important. It can detect and correct certain errors at the receiving end.

9. Monitor and Control Module:

Used to monitor system status, such as optical power, temperature, etc., and make adjustments when necessary.

10. Patch Panel & Fiber Connectors:

used for physical connection and management of fiber paths.

11. Protection Switching:

When the main line fails, it can quickly switch to the backup line.

The above is just a basic list, and actual configurations may vary based on specific design, distance, budget, and other needs. When selecting devices, it is important to ensure that they all support 400G rates and are compatible with each other.
