FAQs

Q: What distance can this optic support?
A: Up to approximately 40 km over single-mode fiber, subject to link loss and dispersion.

Q: What fiber should I use?
A: OS2 single-mode LC-LC duplex fiber is recommended for 1550 nm long-reach links.

Q: Can it interoperate with third-party 1550 nm OC-12 optics?
A: Yes, when the far-end module matches OC-12/STM-4 L-4.2 at 1550 nm and the optical budget is compatible.

Q: Is this for Ethernet traffic?
A: No. It is intended for SONET/SDH circuits at 622 Mb/s.
