Since the advances in Ethernet technology, “last mile” connectivity is expected to realize between the network backbone and local area networks (end users). Gigabit Passive Optical Network (GPON) is a cost-effective point-to-multipoint access network, which brings great improvement in data transmission distance (up to 20km) and bandwidth (an downstream capacity of 2.5Gbit/s and an upstream capacity of 1.25Gbit/s ). However, GPON’s higher bandwidth and split ratios are only achievable by using GPON-capable optical transceivers. It is well positioned to help meet the needs for higher bandwidth in FTTx applications, and continues to fuel growth in demand for GPON SFP modules. So this article will introduce the basics of GPON SFP, including GPON OLT, GPON ONU and GPON ONT SFP module.
Optical components include lasers, splitters, multiplexers, switches, photodetectors and other receiver types, silicon optical benches, and other building blocks of fiber optic communications modules, line cards, and systems. You’ll find new product announcements and tutorial information on this page.
Electronic devices play an important role in optical communications systems. Modulators, laser and modulator drivers, serializers/deserializers (SerDes), PHYs, MACs, multiplexers/demultiplexers, transimpedance amplifiers (TIAs), and similar devices are the core of the technology.
