FAQ:
Q1: What is 200G QSFP56?‌
A1: 200G QSFP56 is a high-speed optical module with 4x53.125Gb/s electrical interface (200GAUI-4), designed for 200G Ethernet and InfiniBand HDR networks in data centers.

Q2: What is 400G QSFP-DD?
A2: It is a high-density, hot-pluggable optical module interface supporting 400Gbps data rates, featuring 8 electrical channels for enhanced bandwidth.

Q3: What are the main types of 400G QSFP-DD modules?
A3: Common variants include SR8 (short-range), DR4/FR4 (intermediate), LR4/LR8 (long-range), and ER4/ER8 (extended-reach), with transmission distances ranging from 100m to 40km.

Q4: How does QSFP-DD differ from QSFP28?
A4: QSFP-DD doubles channel count (8 vs. 4) and supports 50Gbps PAM4 modulation per lane, achieving 4x higher bandwidth while maintaining similar port density.

Q5: What is the maximum transmission distance for 400G QSFP-DD LR4?
A5: The LR4 variant supports up to 10km over single-mode fiber (SMF) using 4x106Gbps lanes, ideal for 5G and cloud interconnects. (https://www.etulinktechnology.com/400g-qsfp-dd-lr4-10km-lc-optical-transceiver_p330.html)

Q6: What is the electrical interface of QSFP-DD?
A6: The module converts 8 channels of 50Gb/s (PAM4) electrical input data to 4 channels of CWDM optical signals and multiplexes them into a single channel for 400Gb/s optical transmission.

Q7: Does QSFP-DD support digital diagnostics?
A7: Yes, it includes DDM (Digital Diagnostic Monitoring) per MSA standards, enabling real-time monitoring of temperature, voltage, and optical power.

Q8: What DAC options exist for 400G QSFP-DD?
A8: Available configurations include direct QSFP-DD-to-QSFP-DD, or breakout to 2x200G QSFP56/4x100G QSFP56/8x50G SFP56 for flexible scaling.

Q9: What is 400G OSFP?‌
A9: The OSFP (Octal Small Form-factor Pluggable) is a 400G optical module standard with 8 electrical channels, designed for high-speed data transmission in data centers and telecom networks.

Q10: How does OSFP differ from QSFP-DD?‌
A10: OSFP has a larger form factor and non-compatible electrical interfaces, while QSFP-DD is backward-compatible with QSFP28 modules.
