PRODUCTION LINE INTRODUCTION

JFOPT continues to invest in optical transceiver production, covering a full range of optical transceiver such as 1*9, SFP, 10G, 25G, 100G, 200G, 400G, 800G GPON/EPON/XG/XGSPON OLT transceiver. At the same time, our company provides TOSA, ROSA, BOSA semi-finished device solutions for the downstream peer. JFOPT's production line has a daily production capacity of 10,000 optical transceivers and 20,000 optical devices. In addition, JFOPT's optical transceiver have industry-leading high temperature resistance and anti-interference capability, and are widely used in computing centers, operators, traffic security, power facilities and other industries.

PRODUCT PRESENTATION

The JFOPT 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.
