Dell 800G QSFP-DD LR8 – QSFP-DD LR8 Optical Transceiver

About Dell 800G QSFP-DD LR8 Optical Transceiver in Bangladesh

The Dell 800G QSFP-DD LR8 is an ultra-high-speed optical transceiver designed for 800Gbps Ethernet connectivity over single-mode fiber. Using the QSFP-DD form factor and LR8 long-reach optical architecture, it is intended for high-bandwidth data center, AI infrastructure, network aggregation, and data center interconnect applications.

The 800G LR8 architecture uses eight optical channels operating at approximately 100Gbps per lane with PAM4 modulation. It is designed to provide long-reach connectivity over single-mode fiber, with LR8 implementations commonly supporting up to 10km under compatible optical conditions.

The transceiver is suitable for high-density Ethernet environments where 800Gbps connectivity is required between compatible switches, routers, spine-leaf fabrics, data center interconnect equipment, and other high-performance networking platforms. Actual compatibility, reach, connector configuration, and supported breakout modes depend on the exact module and host equipment.

Dell 800G QSFP-DD LR8 Optical Transceiver Specifications & Overview

Overview

The Dell 800G QSFP-DD LR8 is designed for next-generation high-density Ethernet networks requiring 800Gbps optical connectivity. Its QSFP-DD form factor combines high bandwidth with efficient front-panel port density, making it suitable for modern data centers, AI clusters, cloud infrastructure, and high-performance network fabrics.

The LR8 optical architecture uses eight 100G PAM4 optical channels and single-mode fiber to achieve long-reach transmission. LR8 modules are commonly designed for links of up to 10km, making them suitable for applications that extend beyond conventional short-reach data center optics.

Compared with shorter-reach 800G SR8 or DR8 solutions, LR8 is intended for significantly longer optical links. This makes it particularly useful for data center interconnects, metro-scale connections, network aggregation, and high-capacity backbone segments where single-mode fiber is already deployed.

Frequently Asked Questions (FAQ)

Q1: What is the data rate of the Dell 800G QSFP-DD LR8?
The LR8 transceiver is designed for up to 800Gbps Ethernet connectivity.

Q2: What form factor does the 800G LR8 use?
The product is specified as a QSFP-DD optical transceiver, a high-density pluggable form factor designed for high-speed Ethernet applications.

Q3: What does LR8 mean?
LR8 refers to a long-reach 800G optical architecture using eight optical lanes. The eight lanes typically operate at approximately 100Gbps each using PAM4 modulation.

Q4: What type of fiber does an 800G LR8 use?
LR8 is designed for single-mode fiber (SMF) long-reach applications.

Q5: What is the maximum reach of an 800G LR8?
800G LR8 implementations are commonly designed for up to 10km over compatible single-mode fiber. Actual reach depends on the exact transceiver, fiber plant, optical budget, and host equipment.

Q6: What modulation does the 800G LR8 use?
Typical 800G LR8 designs use PAM4 modulation across eight optical lanes.

Q7: Is 800G LR8 suitable for data centers?
Yes. It is particularly suited to high-bandwidth data center fabrics, AI infrastructure, cloud networking, spine-leaf architectures, and data center interconnects requiring long-reach 800GbE connectivity.

Q8: What is the difference between 800G SR8, DR8 and LR8?
SR8 is intended for short-reach multimode-fiber connectivity, DR8 for shorter single-mode-fiber links, and LR8 for longer single-mode-fiber links, commonly up to around 10km depending on the implementation.

Q9: Is every QSFP-DD port compatible with 800G LR8?
No. The host platform must specifically support the required 800G electrical interface, optical module type, power and thermal requirements, firmware, and transceiver coding. Always verify the equipment compatibility matrix.
