I. Product Description
The Mellanox MC2210511-LR4 is a 40GbE QSFP+ LR4 optical module.
1. Form Factor: QSFP+
This is a plug-in module specification widely used in high-speed network devices. QSFP+ supports 4-channel parallel transmission,
with each channel having a data rate of 10 Gbps, aggregating to a total bandwidth of 40 Gbps. Its size is larger than that of the earlier SFP+,
designed for high-density and high-speed applications.
2. Data Rate: 40 Gigabit Ethernet (40GbE)
This is a module for the 40 Gigabit Ethernet standard.
3. Transmission Distance and Type: LR4
LR stands for Long Reach.
4 indicates it uses 4 different wavelengths of lasers (WDM technology).
It transmits through single-mode fiber (SMF).
The maximum transmission distance can reach up to 10 kilometers.
4. Interface and Fiber Connector:
One end of the module has a standard QSFP+ gold finger interface, used for insertion into the QSFP+ ports of switches, routers, or network cards.
The other end is a duplex LC fiber interface. It should be noted that although QSFP+ has 4 channels internally, the LR4 technology couples the 4 wavelengths of optical signals into one fiber for transmission,
and another fiber is used for receiving, so only one duplex LC interface (one transmit and one receive) is needed externally.
5. Wavelength and Technology:
It operates in the CWDM (coarse wavelength division multiplexing) band.
The center wavelengths of the 4 channels are 1271nm, 1291nm, 1311nm, and 1331nm. At the transmitting end,
the optical signals of these four wavelengths are multiplexed into one fiber; at the receiving end, they are demultiplexed into four independent signals.
6. Digital Diagnostic Monitoring (DDM / DOM):
This module supports DDM functionality, meaning that the working status of the module can be monitored in real time through compatible network devices (such as Mellanox switches),
for example:
Transmitted optical power, received optical power, operating temperature, supply voltage, laser bias current, which are crucial for network operation, fault diagnosis, and early warning.
7. Power Consumption:
The typical power consumption is usually below 3.5W, which is at a relatively low level among similar products, facilitating high-density deployment and energy conservation.
8. Compatibility:
Although it is of the Mellanox brand and can achieve the best compatibility and performance when used with Mellanox (now NVIDIA) switches and network cards (such as ConnectX-3, ConnectX-4 series),
it also follows the universal MSA (multi-source agreement) standard. This means it may be used on other devices that support the 40G QSFP+ LR4 standard,
such as certain devices from brands like Cisco, Arista, Juniper, etc., but it is strongly recommended to check the compatibility list before use to avoid incompatibility issues.
II. Usage Scenarios
The core value of this optical module lies in the medium-long distance 40G high-speed interconnection. Its main application scenarios include:
1. Data Center Inter-Switch Links (DC-SSL)
This is the most typical application. When core switches, aggregation switches, or spine switches are located in different buildings or within the same campus but within a 10-kilometer distance,
MC2210511-LR4 is an ideal choice. It can provide high-speed and stable 40G connections over single-mode optical fibers.
2. High-performance computing (HPC) and artificial intelligence (AI) cluster interconnection
HPC and AI clusters require extremely low latency and extremely high bandwidth for communication between nodes (such as through InfiniBand or RoCE). Mellanox devices are leaders in this area.
When computing nodes, storage nodes, or gateway devices need to be connected over long distances (such as between different buildings within a campus), this LR4 module comes in handy.
3. Enterprise network core backbone connection
The core layer of large enterprises or campus networks requires high-speed backbones to converge traffic.
The 40G LR4 module can be used to connect core routers and switches located in different geographical locations to build a high-performance network backbone.
4. Storage area network (SAN) expansion
If storage devices (such as SAN) need to be connected to servers or another data center several kilometers away,
The speed of 40G can well meet the bandwidth requirements of storage networks (such as NVMe over Fabrics, iSCSI, Fiber Channel over Ethernet).
5. Telecommunications and service provider networks
For metropolitan area network (MAN) access or aggregation, providing 40G uplink links for base station controllers, core network element devices, etc.
