Q: How does the performance of these compare to original brand optics? Are they really just as good but cheaper? By A***n on 2026-06-03
A: You get the exact same core performance. Our transceivers use premium DFB lasers and PIN receivers, matching the strict hardware specs of OEM parts from Cisco, Juniper, or Dell. It’s a highly cost-effective alternative with absolutely zero compromise on signal integrity. By admin on 2026-06-03
Q: Can I use standard LC duplex multimode fiber with this module, or do I strictly need single-mode? By A***z on 2026-05-19
A: You must use Single-Mode Fiber (SMF) paired with an MPO-12/APC angled connector. This module relies on a 1310nm wavelength for up to 10km transmission, meaning standard LC multimode cables are neither physically nor optically compatible. By admin on 2026-05-19
