In today’s fast-paced world, having a high-speed network is crucial for any business to stay competitive. If you’re currently using a 10G network and looking to upgrade to 40G to increase your data transfer speeds, fiber cables are the way to go. In this blog, we’ll walk you through the steps of upgrading your network using fiber optic cables.
Why Do You Need to Upgrade from 10G to 40G?
Before we begin, let’s explore why such an upgrade is necessary.
As businesses grow and their data needs continue to increase, so does the demand for higher bandwidth capacity. Modern applications such as cloud computing, 4K video streaming and virtualization require significant bandwidth to operate efficiently. As the volume of data continues to grow, 10Gbps may no longer suffice, leading to issues such as delays and network congestion.
40G connectivity, with 4x the bandwidth of 10G networks, can better accommodate future growth and handle increasing traffic volumes and larger file sizes more efficiently. It allows for faster data transfer speeds, reduced latency and improved network performance. While the initial cost of upgrading to a 40G network may be higher, the increased bandwidth can lead to cost savings in the long run by reducing the need for frequent upgrades.
How to Upgrade from 10G to 40G Networks?
Solution 1: LACP Configuration
LACP allows you to combine multiple 10G links to create a single 40G logical link. By aggregating these fiber links, you can increase your network bandwidth without the need for additional hardware. This method is ideal for businesses that already have multiple 10G connections in place and want to efficiently upgrade to 40G without major disruptions.
Key Components:
Before jumping to the setup, it’s better to familiarize yourself with the components required for this configuration:
- Network Switch with 4*10G SFP+ Ports: Serve as the central hub where the 10G ports will be aggregated into a 40G link. Each SFP port provides a dedicated 10Gbps connection for high-speed data transmission. Ensure the switch supports LACP for link aggregation.
- 4 Strands Pre-terminated Fiber Optic Cable: Consist of four individual optical fibers within a single jacket. Each fiber can carry data independently, typically using different wavelengths, or you can combine multiple data streams into one.
- 10G BiDi SFP+ Modules: Transmit and receive optical signals over a single fiber strand and carry data at high data rates of 10Gbps or even higher.
Step-by-Step Tutorial
Now, follow the instructions below to group 4*10G SFP+ ports into a 40G link:
Step 1: Install the 10G SFP+ Modules
Identify the 10G SFP+ ports on each switch and insert the 10G SFP+ modules into the SFP+ ports on each switch. Align the module with the port and gently push until it clicks into place. Repeat this process for all four SFP+ ports on both Switch A and Switch B. Ensure that the SFP+ modules are compatible with the switch model and are inserted correctly to avoid damage.
Step 2: Connect the Network Switches
Connect Strand A of the fiber optic cable to the SFP+ module in port 1 of Switch A. Then, connect the other end to the SFP+ module in port 1 of Switch B. Repeat this process for Strands B, C, and D, connecting them to ports 2, 3, and 4 respectively, on both Switch A and Switch B. Ensure all the connections are secure and all the fibers are not bent or strained excessively.
Step 3: Configure LACP for Link Aggregation
Next, you need to configure LACP on your network switch to group the 10G ports into a single 40G link. It helps distribute traffic evenly across the aggregated ports, providing load balancing and redundancy in case of link failure.
- Log in to the switch interface and configure LACP for the 4*10G ports that you want to group into a 40G link.
- Create a LAG (Link Aggregation Group) and assign the 4*10G SFP+ ports to it. This will combine the bandwidth of the individual ports into a single logical link.
- Specify the LACP mode, active or passive. This must match on both switches.
- Apply the configuration and save changes on both switches.
- Verify the aggregated 40G link by testing data transfer between devices connected to Switch A and Switch B.
Solution 2: MTP/MPO Cables
Upgrading to 40G using MTP/MPO cables offers several benefits, especially in terms of scalability, efficiency, and cost-effectiveness in high-density data centers. And there are two methods to do so: breakout connection or direction connection.
A.Breakout Connection
MTP/MPO to LC breakout cables allow a single high-speed connection (40Gbps) to be split into four lower-speed connections (4 x 10Gbps). This flexibility is useful for connecting to equipment that uses SFP+ ports, such as your 10G switch. These cables feature an MTP/MPO connector on one end, which fans out into multiple LC connectors on the other end. Each LC connector corresponds to a separate data stream, effectively breaking out the 40G signal into four individual 10G connections.
Key Components:
- 40G QSFP+ Transceiver: Ensure high-speed connectivity for 40G networks, typically used in data centers over short distances.
- 10G SFP+ Transceivers: Transmit and receive optical signals over a single fiber strand and carry data at high data rates of 10Gbps or even higher.
- MTP to LC Breakout Cable: Efficiently convert high-density MTP connectors to LC connectors, facilitating different optical standards in data centers.
- 40G Switch: Manage network traffic and support aggregation and distribution of data across the upgraded network.
- 10G Switch: Ensure your existing 10G switch has 4*10G SFP+ ports for link aggregation.
Steps:
1.Insert the QSFP+ transceiver into the QSFP+ port on the 40G switch.
2.Insert SFP+ transceivers into the 10G SFP+ ports on your existing 10G switch.
3.Attach the MTP/MPO end of the breakout cable to the QSFP+ transceiver on the 40G switch.
4.Connect each LC connector from the breakout cable to the SFP+ transceiver on the 10G switch.
5.Power on the switches and check the status lights on both switches and verify that the link is up between them.
B.Direct Connection
In a direct connection, a 40G connection is achieved by using a single MTP connector on both ends of the link. MTP/MPO is a high-density fiber connector that can support multiple fibers in a single connection. By using MTP cables, you can easily upgrade from 10G to 40G without the need for individual fiber cables. Simply connect the MTP cable to your existing 10G infrastructure and configure your network settings accordingly.
For a 40G upgrade, you also need to verify if your current switch supports 40G speeds. If not, you should upgrade to new hardware that does.
Key Components:
- 40G Switches: Obtain network switches that have at least one QSFP+ port that is capable of handling 40G data rates.
- MTP/MPO Cables: Acquire high-quality MTP cables. MTP cables come in different fiber counts (e.g., 12-fiber, 24-fiber) and polarities (Type A, B, C), so choose according to your design.
- 40G QSFP+ Transceivers: Purchase 40G QSFP+ transceivers that are compatible with your switches and the MTP cables.
Steps:
1.Insert the 40G QSFP+ transceivers into the designated ports on the 40G switches.
2.Take the MTP cable and connect one end to the QSFP+ transceiver on Switch 1.
3.Connect the other end of the cable to the QSFP+ transceiver on Switch 2.
4.Power on the switches and verify the link status. Use testing tools to ensure that data is flowing correctly at 40G speeds between the switches.
