What are the characteristics of NG PON2?
NG-PON2 characteristics
- NGPON2 (TWDM) expansible from 40Gbps: 4 wavelengths @ 10Gbps per wavelength today moving to 8x80Gbps in future.
- Bonding capable: Multiple wavelengths may be channel-bonded to provide > 10Gbps services with standards work in progress.
What is Xgs-PON?
XGS-PON is an updated standard for Passive Optical Networks (PON) that can support higher speed 10 Gbps symmetrical data transfer and is part of the family of standards known as Gigabit-capable PON, or G-PON.
Is Xgs-PON shared?
XG-PON1 and XGS-PON are single channel technologies which share the bandwidth provided, depending on the split ratio. Because of their simplicity, fixed wavelength technologies typically have lower cost optics.
What is after GPON?
After GPON will come the 10G PON era which is also called NG-PON Phase 1, including XG-PON and XGS-PON. Then, there will be the 40G PON era featuring the time wavelength division multiplexing (TWDM) PON technology, which is also called NG-PON Phase 2.
What is Xgs-PON vs GPON?
XG-PON is essentially a higher bandwidth version of GPON. It has the same capabilities as GPON and can co-exist on the same fiber with GPON. XG-PON has been minimally deployed to date. XGS-PON (10G down / 10G up): ITU G.
What protocol does GPON use?
GPON uses an IP-based protocol and either ATM or GEM (GPON encapsulation method) encoding. Data rates of up to 2.5 Gb/s are specified and it is very flexible in what types of traffic it carries. GPON enables “triple play” (voice-data-video) and is the basis of most planned FTTP applications in the near future.
Is GPON a fiber?
GPON is a telecommunications access technology that uses fiber-optic cabling to reach the user. This fiber optic technology provides faster data transmission and reception through a single fiber, with a point-to-multipoint architecture, which allows home optical fiber (FTTH), or a building (FTTB).
What OSI layer is DWDM?
If you are working in the transport networking, you already know that Layer 0 is the photonics layer, more specifically, DWDM is considered as the Layer 0 of the OSI layers.
What is split ratio in GPON?
GPON-capable optical transceivers feature a 28-dB optical loss budget to enable 1:64 split ratios and provide adequate optical loop lengths for most subscribers.
What is GEM port and Tcont?
GEM Port: A GPON Encapsulation Method (GEM) port is a virtual port for performing GEM encapsulation for transmitting frames between the OLT and the ONU/ONT. Each different traffic-class (TC) per UNI is assigned a different GEM Port. Each T-CONT consists of one or more GEM Ports.
What is the speed of GPON?
2.488 Gb/s
GPON speeds The most common GPON standard permits a capacity on each “trunk” line of 2.488 Gb/s on the downstream, and a maximum upstream capacity of 1.244 Gb/s.
What is PON plant?
Pon is a substrate—or growing medium—that can be used in place of soil. If you speak to a plant parent who is familiar with pon, they’ll most likely mention the brand Lechuza, a company that creates many self-watering planters that help prevent overwatering (I made need to buy one for my poor Asparagus Fern).
What happened to FSAN on XG-PON1?
Further FSAN work on XG-PON1 is now largely handled by the O&E Task Group with a major focus on interoperability. Since completing the work on XG-PON1, the NG-PON Task Group has focussed effort on NG-PON2 systems (ITU-T G.989 series).
What is NG-PON2?
The system is termed NG-PON2 and offers a fiber capacity of 40 Gbit/s by exploiting multiple wavelengths at dense wavelength division multiplexing channel spacing and tunable transceiver technology in the subscriber terminals (ONUs).
What is the FSAN NG-PON task group?
The FSAN Next Generation Passive Optical Network (NG-PON) Task Group has the objective of capturing Operator requirements and developing specifications for optical access systems beyond those currently standardised.
