The ZIBBIX EPON OLT PON PX20+++ (and similar, such as Corelink, ECOM, or V-SOL branded PX20+++ modules) is a high-performance, hot-swappable optical transceiver designed for Gigabit Ethernet Passive Optical Network (EPON) systems. It is primarily used to deliver fiber-to-the-home (FTTH) or fiber-to-the-building (FTTB) services.
Data Rate: 1.25 Gbps bidirectional (1490nm continuous-mode transmitter and 1310nm burst-mode receiver).
Output Power: High power level (+6dBm to +10dBm range, commonly +9dBm or +7/8/9dBm) which provides superior signal strength for longer distances compared to PX20 or PX20+ modules.
Transmission Distance: Up to 20km or 40km depending on fiber quality and deployment.
Connector Type: SC/UPC.
Compatibility: Widely compatible with major EPON OLT equipment vendors, including BDCOM, ZTE, Huawei, and Fiberhome, as well as TPLINK and Ubiquiti.
Monitoring: Supports DDM/DOM (Digital Diagnostic Monitoring) for tracking real-time transceiver parameters like operating temperature, received optical power, and transmitted power.
Use Cases and Advantages
High Power Performance: The PX20+++ class offers increased optical budget compared to standard PX20+, making it ideal for networks with high split ratios (e.g., 1:64).
Reliability: Designed for high-speed data transmission in FTTx scenarios.
Hot-Swappable: Supports easy insertion and removal from OLT devices.
These modules are widely available through distributors in Bangladesh and electronics marketplaces, often used to upgrade existing OLT infrastructure to support stronger signals
