Q1: What does OSFP112 mean compared to standard OSFP?
A: OSFP112 supports 112G electrical lanes, enabling higher-performance 400G and future 800G architectures compared to traditional OSFP designs.

Q2: What is the advantage of PAM4 in this transceiver?
A: PAM4 modulation doubles the data rate per lane compared to NRZ, enabling 400G transmission using fewer lanes and improving bandwidth efficiency.

Q3: What fiber type is required for SR4 modules?
A: SR4 modules use multimode fiber, typically OM3 or OM4, with MPO/MTP parallel fiber connectors.

Q4: Can this module reach the full 100m distance?
A: Yes, up to 100m is achievable on OM4 fiber under proper link budget and low-loss connector conditions.

Q5: Is this module suitable for AI GPU clusters?
A: Yes, it is specifically designed for high-bandwidth, low-latency AI and HPC environments requiring dense 400G interconnects.

Q6: What is the difference between SR4 and SR8?
A: SR4 uses 4 optical lanes at higher per-lane speed, while SR8 uses 8 lanes at lower per-lane speed, depending on system architecture.
