Bitdefender 3129ZZBSR240JLZZ SFP+ 10G DWDM Transceiver

Keep critical network links stable across extended distances with this 10GBase-DWDM SFP+ transceiver. Built for single-mode fiber environments, it supports 10 Gigabit Ethernet over LC connectivity and is specified for up to 80 km reach at 1531.12 nm. That makes it a strong fit for data center interconnects, campus backbones, and optical transport paths where link budget and signal integrity matter. This module is designed for Arista Networks SFP-10G-DZ-31.12 compatible environments and supports DOM, giving infrastructure teams the visibility needed to monitor optical performance and maintain service levels. Its 50 GHz DWDM design helps preserve dense channel planning in networks where spectrum efficiency matters. For teams standardizing on high-reliability optics, this transceiver offers the reach, compatibility, and operational control expected in production networks. When the cost of a link failure is measured in downtime, this is the kind of component that earns its place: precise wavelength control, long-distance performance, and compatibility with established switching platforms.
