This module is strictly designed for single-mode fiber. While mode-conditioning patch cables can sometimes adapt 1310nm optics to multimode glass, they are not designed or specified for CWDM wavelengths like 1410nm. For reliable data transmission and full reach, you should only deploy this module over single-mode fiber. By

We set up an isolated management network across our metro ring using this specific 1410nm wavelength. Because it runs alongside other active optical channels, clean wavelength isolation was critical. The transceiver stayed right on its frequency with zero interference to neighboring channels. Packet latency is completely flat, and data transfers are fast and stable.

High-quality optical hardware that works straight out of the box. We tested the link across our fiber patch field with around 10dB of loss, and the receiver picked up the signal with plenty of safety margin to spare. Standard MSA design means it fits neatly into compact multi-port switch faces without blocking neighbor ports.

Installed this module in an outdoor utility enclosure to send control data back to our central office over 14km of single-mode fiber. The module handled the wide daily temperature swings inside the metal box without any signal drift or disconnects. The duplex LC ports hold the fiber connector firmly, and the built-in diagnostics let us verify signal health in seconds =D

Signal power is right on target around -2 dBm on the transmit side. The receiver has plenty of sensitivity left over after going through two patch panels and a 10km run.
