Nokia 3AL82242AA refers to a QSFP-DD packaged, 400Gbps rate, 10-kilometer transmission distance optical transceiver. This is a high-speed optical module launched by ,
Nokia for high-performance data center interconnection (DCI) and enterprise core networks. Here is a detailed description and key features of the product:
1. Packaging Form:
QSFP-DD: This is the current mainstream packaging standard for 400G high-speed optical modules. It provides 8-channel electrical interfaces (each channel at 50Gbps PAM4),
achieving a total bandwidth of 400Gbps. The QSFP-DD interface is backward compatible with QSFP28 (100G) and QSFP+ (40G) modules (with the need for corresponding adapters or cables).
2. Rate and Protocol:
400 Gigabit Ethernet (400GbE): Fully compliant with the IEEE 802.3bs 400GBASE-LR8 standard.
OTU4: Also typically supports the OTU4 rate (~400G) of the OTN (Optical Transport Network), used for carrier-grade transmission.
3. Transmission Distance:
10 kilometers: This is one of the core features of the module. It is designed to achieve a transmission distance of up to 10 kilometers through standard single-mode fiber.
This makes it highly suitable for campus network interconnection, metro access networks, and medium-distance connections between data centers (DCI).
4. Fiber Type and Wavelength:
Fiber Type: Single-mode fiber.
Wavelength: Compliant with the 400GBASE-LR8 standard, using 8 independent wavelength channels, typically within the O-Band range of 1295nm to 1325nm (for example,
the central wavelength is often around 1310nm). Each channel operates at 50Gbps PAM4 modulation.
Interface: The front end of the module is a dual LC optical fiber interface. One LC interface is for transmission (Tx), and the other for reception (Rx). Although there are 8 independent channels internally,
they are multiplexed onto a pair of fibers through wavelength division multiplexing technology on the fiber.
5. Key Performance Indicators:
Modulation Format: PAM4 (4-level Pulse Amplitude Modulation), which is the key technology for achieving 50Gbps/channel and 400G total rate.
Power Consumption: The typical power consumption of the QSFP-DD 400G LR8 module is usually within < 12W (the exact value needs to be checked in the latest Nokia specification,
but this is the industry mainstream level). Nokia usually pays attention to energy efficiency design.
Operating Temperature Range: Commercial or extended temperature range. Common specifications include 0°C to +70°C (COM), or a wider range such as -5°C to +75°C/85°C (EXT).
Specific details need to be referred to in the product specification.
Digital Diagnostic Monitoring: Supports standard DDM/DOM functions, allowing real-time monitoring of the module through the I2C interface of the host device for:
Temperature, supply voltage, transmit optical power, receive optical power, laser bias current, alarms and alarm thresholds, module type, serial number, production date, etc.
6. Main Application Scenarios:
Data Center Interconnection: Connecting geographically adjacent (within 10km) data centers.
Enterprise Core Network/Park Backbone: Connecting core switches or routers in different buildings within a large campus.
Telecom metro access and aggregation: 400G high-speed uplink for mobile fronthaul, midhaul or fixed broadband aggregation nodes.
High-performance computing networks: Scenarios requiring ultra-high bandwidth interconnection.
Cloud service provider networks: Building high-speed backbone networks.
7. Nokia-specific information:
Model: 3AL82242AA is an internal part number (FRU) of Nokia.
Compatibility: This module is designed for Nokia routers and switch platforms that support QSFP-DD interfaces, such as its IP routing platforms and some data center switches.
It is essential to confirm its compatibility with your specific equipment in Nokia's official documentation or compatibility list.
Quality and reliability: As a Nokia product, it typically undergoes rigorous testing and certification to meet the reliability and performance requirements of carrier-grade networks.
