Since the advances in Ethernet technology, “last mile” connectivity is expected to be realized 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 (and 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.
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.
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.
5G is another area where fiber networks are utilized. The hope is that once all of 5G’s components are fully deployed and operational, you will not need any kind of wire or cable to deliver communications or even entertainment service to your mobile device, to any of your fixed devices (HDTV, security system, smart appliances), or to your automobile. If everything works, 5G would be the optimum solution to the classic “last mile” problem: Delivering complete digital connectivity from the tip of the carrier network to the customer, without drilling another hole through the wall.
