Hardened SFPs

As more industrial and outdoor networking applications call for fiber optic cable, hardened SFPs provide reliable fiber-optic connectivity in extreme environmental conditions.

Key hardening features include extended ranges of operating temperature which can range up to -40°C to 85°C (depending on cable/connector type). Digital diagnostic features that decrease downtime resulting from link loss and other flags which is an advantage in hardened applications. Like all SFPs, hardened SFPs must be compliant with the Multi-Sourcing Agreement (MSA).

Transition Networks’ Hardened SFP transceiver modules are the ideal solution to provide the right connections in your hardened network. Our SFP modules support a variety of distances as well as data rates to make connecting fiber or copper in your network quick and easy. Also, our hardened SFPs are available as Cisco compliant to provide better cross-platform connectivity. View our Hardened SFP modules below.
