This industrial-grade 10G DWDM module went into a roadside network cabinet for a backhaul project. The −40 to 85°C temperature range was the main reason we selected it, but the optical power readings in DOM have also been very useful during acceptance testing.

Deploying high-density optical gear inside unheated or non-air-conditioned roadside cabinets presents constant thermal challenges. We fielded a batch of these industrial-grade 10G DWDM modules across several field sites where ambient temperatures fluctuate drastically throughout the day. The optics maintained steady laser output power and tight wavelength stability on C28 (1554.94nm) without experiencing thermal frequency drift. Having reliable DDM diagnostics exposed directly via SNMP helped our network operations center monitor operating metrics remotely during heat waves. Highly recommended for field engineers building ruggedized fiber backhauls.
