Description
The Infinera OFM-4-D-AV-1821 is a robust optical filter module engineered for high-capacity optical transport networks. Designed to support dense wavelength division multiplexing (DWDM) applications, this unit enables efficient signal routing and wavelength management across long-haul and metro networks. Housed in a compact, rack-mountable chassis, it integrates seamlessly into existing Infinera platforms, offering flexibility and scalability for evolving infrastructure needs. Its passive optical components are built for durability and long-term performance, making it a reliable choice for second-hand deployment.
This model supports a 4-degree ROADM (Reconfigurable Optical Add-Drop Multiplexer) configuration, enabling dynamic wavelength routing across multiple network paths. The OFM-4-D-AV-1821 includes advanced wavelength selective switches (WSS) and arrayed waveguide gratings (AWG), providing precise signal filtering and minimal insertion loss. Compatible with the Infinera DTN-X and FlexILS systems, it operates within the C-band spectrum, supporting up to 96 channels at 50 GHz spacing. With low power consumption and minimal maintenance requirements, it remains a cost-effective solution for expanding optical capacity in legacy or current network environments.
