PRODUCT PRESENTATION
The PHILISUN EPON OLT PX20+++ 9dBm Transceiver represents the industry-leading 1.25G SFP solution for Optical Line Terminals, enabling 1490nm downstream transmission and 1310nm upstream reception over single-mode fiber (SMF) with 20km reach. Featuring an SC connector and delivering the highest available 9dBm optical budget in the PX20+++ class, this transceiver incorporates 100 Ohm differential impedance on both transmitter inputs and receiver outputs. Its architecture employs internal AC coupling on data lines, provides precision differential termination, and minimizes differential-to-common mode conversion to ensure uncompromising signal integrity, premium termination quality, and ultra-low electromagnetic interference (EMI) performance.
