Fiberbit Ethernet Passive Optical Network (EPON) PX20 SFP/SFF OLT transceivers support 1000BASE-PX20-D for 20 km applications. The PE21143xxCx EPON SFP/SFF OLT transceivers are a family of high performance optical modules providing a symmetric 1.25 Gb/s downstream and 1.25 Gb/s upstream data link over a single fiber using a 1490 nm continuous-mode transmitter and 1310 nm burst-mode receiver. SFP package has an SC/UPC receptacle.  The transmitter section uses a 1490 nm DFB  (Distributed FeedBack) laser for superior performance and is Class 1 laser compliant. The receiver section uses a 1310 nm APD, preamplifier, and limiting post-amplifier. The receiver does not  require a reset pulse between incoming optical packets of varying signal strength.

Fiberbit EPON SFP OLT transceivers support a two wire serial interface for Digital Diagnostic Monitoring. The SFP OLT transceiver supports RSSI receive
signal strength indication

Modern networks rarely rely on pure topologies like bus, ring, or star. Most common solutions use hybrid topologies, which are combinations of features from those three.   Star-Wired Ring As it is clear from the name, star-wired ring topology has features of star and ring topologies. You can see example of this topology ...
