Description
The AddOn Juniper Networks® Compatible Q28-100GP4-BXD3129-20-J-AO is a high-performance 100GBase-BX LR1 PAM4 QSFP28 optical transceiver designed for 20km transmission over single-mode fiber (SMF). It uses a 1311nm transmit and 1291nm receive wavelength via a bidirectional LC connector, offering exceptional efficiency and bandwidth for next-generation data center and enterprise network deployments.
Engineered to meet or exceed OEM specifications, this hot-swappable module ensures seamless interoperability with Juniper Networks® platforms. It is compliant with QSFP28 MSA and SFF-8636 Rev 2.10a, supports a 4x25G electrical interface, and includes Digital Optical Monitoring (DOM) for real-time diagnostics of critical parameters.
Each transceiver undergoes extensive data-traffic and application testing, is RoHS compliant and lead-free, and is backed by AddOn’s limited lifetime warranty. TAA compliance ensures suitability for U.S. Government and public sector deployments.
