FAQs

Q: Can I reuse existing duplex LC MMF cabling?
A: Yes, SR1.2 BiDi is designed for duplex LC multimode links, enabling 100G without MPO infrastructure.

Q: What is the supported reach on OM3 vs OM4?
A: Up to 100m on OM4; OM3 may be supported at reduced distances depending on fiber quality.

Q: Is this compatible with standard SR4 optics?
A: No, SR1.2 BiDi uses duplex LC and bidirectional wavelengths; it does not interoperate with MPO-based SR4 on the same link.

Q: Does it provide DOM/DDM telemetry?
A: Yes, it supports real-time digital diagnostics.

Q: Is breakout to 4x25G supported?
A: No, SR1.2 BiDi is a duplex 100G solution and does not support 4x25G breakout.
