The ZPI BP3AM1DE-22-A BTI Systems® Compatible SFP transceiver operates at 155M with a wavelength of ITU CH47 1539.77nm with a maximum reach of 120km. 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 BP3AM1DE-22-A is individually programmed in-house and then Spirent® tested for performance and functionality as well as compatibility tested in target BTI Systems® platforms. Old and new revisions of BTI Systems® operating software are used for testing to ensure 100% compatibility. ZPI 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 ZPI BTI Systems® compatible transceivers are MSA compliant for seamless integration and RoHS compliant for environmental conformity. All ZPI transceivers are backed by a Lifetime Replacement Warranty.
