FR4 uses duplex LC interfaces with CWDM EML lasers for up to 2km single-mode links, saving fiber compared to DR4 which uses MPO connectors and supports only 500m.
No. FR4 uses duplex LC and is designed for 400G full-rate links; for breakout scenarios, XDR4 modules with MPO connectors are recommended.
The onboard DSP with gearbox function converts 8x50G electrical signals into 4x100G PAM4 optical signals for FR4 transmission over single-mode fiber.
Use single-mode duplex LC/UPC SMF. Ensure the patch cables are compliant and clean for optimal signal quality over the 2km distance.
It is commonly used for spine-to-spine interconnects or leaf-to-spine connections in large-scale data centers with 400G QSFP-DD switches.
All items exceeded our expectations. Arrived on time and quality is excellent, no complaints.
Every module works fine without any errors. Overall performance is very stable.
