XPON SFP Transceivers-- Find the rignt mode for your Data Center
XPON SFP Transceivers--- Find the Right Mode for your Data Center.
XPON SFP transceivers mean GPON/GEPON SFP Transceivers. Are you still confused how to choose XPON SFP? Can't find the right mode? Please do not worry. Here we will give you some suggestions make choice.
10G-PON
Asymmetric 10G-PON is specified as XG-PON1: 10 Gbit/s downstream and 2.5 Gbit/s upstream. Symmetric 10G-PON is also proposed as XG-PON2 with 10 Gbit/s upstream, but would require burst-mode lasers on ONTs to deliver the upstream transmission speed.
GPON
Gigabit Passive Optical Networks (GPON) is the leading technology being used in FTTx (FTTH) deployments.
GEPON
Ethernet Passive Optical Networks (GEPON or EPON) is the leading technology being used in FTTx (FTTH) deployments.
GPON stick
The GPON Stick provides a pluggable GPON interface for FTTx and wireless backhaul applications with a compact size and lower power consumption
GEPON Stick
The GEPON Stick provides a pluggable GEPON ONU interface switches, routers, wife customer devices with a compact size and lower power consumption
A passive optical network (PON) is a point-to-multipoint, fiber to the premises network architecture in which unpowered optical splitters are used to enable a single optical fiber to serve multiple premises, typically 16-128. A PON consists of an optical line terminal (OLT) at the service provider's central office and a number of optical network units (ONUs) near end users. A PON reduces the amount of fiber and central office equipment required compared with point-to-point architectures. A passive optical network is a form of fiber-optic access network.
Downstream signals are broadcasted to all premises sharing multiple fibers. Encryption can prevent eavesdropping.
Upstream signals are combined using a multiple access protocol, usually time division multiple access (TDMA). The OLTs "range" the ONUs in order to provide time slot assignments for upstream communication.
