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+++ 8dBm Transceiver is a premium-grade 1.25G SFP module engineered for Optical Line Terminal (OLT) deployments, delivering 1490nm downstream transmission and 1310nm upstream reception over single-mode fiber (SMF) with a 20km reach. Featuring an SC connector interface and compliant with the highest-performance PX20+++ class offering an 8dBm optical budget, it incorporates 100 Ohm differential impedance for both transmitter inputs and receiver outputs. The module utilizes internal AC coupling on data lines, provides optimized differential termination, and significantly reduces differential-to-common mode conversion to ensure exceptional signal integrity, reliable termination quality, and minimized electromagnetic interference (EMI).
