What is GPON mode?
What is GPON mode?
GPON (Gigabit Passive Optical Networks) is an Optical System for the Access Networks, based on ITU-T specifications G. 984 series. It can provide a 20 km reach with a 28dB optical budget (shown in the following illustration) by using class B+ optics with 1:32 split ratio. GPON system supports the following rates −
What are all the GPON network protection modes?
GPON provides a full quality of service assurance (QoS), asynchronous transfer mode (ATM) and the Gigabit-capable Passive Optical Network Encapsulation Method (GEM) [4] .
What is GPON Tcont?
The T-CONT concept is used for GPON upstream data scheduling. It can be regarded as QoS control. In GPON, the T-CONT implements dynamic bandwidth assignment (DBA). It is the basis of DBA implementation and basic control unit of the upstream bandwidth in the GPON system.
What is the difference between GPON and Active Ethernet?
An Active Ethernet network provides each subscriber with their own fiber link to the network node switch, which links the local network to the Internet. In comparison, a GPON network uses passive optical splitters to connect up to 32 subscribers to a single fiber link to the network node.
What is GPON SFP?
What Is GPON SFP? GPON SFP is one type of gigabit optical transceivers that are used in GPON system, which is compliant with ITU-T G. 984.2 standard. It is a bidirectional module that has SC receptacle and works over simplex single-mode fiber optic cable.
Is GPON better than fiber?
The Key Difference GPON fiber optic cable separates data, voice and video onto three different network layers. In contrast, EPON fiber optic cable unifies data, voice and video onto a single network layer. As a result, a GPON network can provide a higher level of service quality for each type of communication.
What is better GPON or EPON?
GPON is superior to EPON from the performance index. However, EPON has the advantage of time and cost. GPON is catching up and looking forward to the future broadband access market.
What is upstream and downstream in GPON?
GPON utilizes both upstream and downstream data by means of Optical Wavelength Division Multiplexing (WDM). In downstream transmission, the lasers wavelength measures 1490 nm while the upstream wavelength measures 1550 nm.
