The ENET MA-QSFP-40G-SR-BD-ENC Meraki® Compatible QSFP+ transceiver operates at 40GBASE-Bi-di with a wavelength of 832-918nm with a maximum reach of 150m. Each is 100% compatible tested in fit form and functionality compared to the OEM product. Our extensive quality control measures begin with physically inspecting each module verification of hardware type wavelength transmit power receive power and full optical monitoring functionality (if applicable). Each MA-QSFP-40G-SR-BD-ENC is individually programmed in-house and then Spirent® tested for performance and functionality as well as compatibility tested in target Meraki® platforms. Old and new revisions of Meraki® operating software are used for testing to ensure 100% compatibility. ENET tests each transceiver using Spirent® Test Centers to emulate live traffic through actual reels of fiber ranging in lengths from 100 meters to over 100 kilometers. These extensive performance testing procedures combined with compatibility testing in more than 80 switches routers and servers guarantees each and every transceiver performs flawlessly in its intended environment. All ENET Meraki® compatible transceivers are MSA compliant for seamless integration and RoHS compliant for environmental conformity. All ENET transceivers are backed by a Lifetime Replacement Warranty.
