Which is better EPON and GPON?
Which is better EPON and GPON?
EPON and GPON have their own advantages and disadvantages. GPON is better than 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.
Is GPON and EPON same?
In fact, both GPON and EPON deliver Ethernet to the end user. The difference is GPON is a purpose-built point to multi-point transport protocol while EPON conscripts Ethernet to attempt the same inefficiently.
What is the bandwidth of EPON?
1 Gbps
Usable bandwidth: 1 Gbps upstream and downstream. Reach: Up to 32 ONUs per OLT. Subscriber cost: Lower than GPON.
Is GPON better?
Its advantage is especially strong where minimizing maintenance work is important. The GPON design includes ATM encapsulation. This makes it convenient to deploy in networks which use an ATM backbone. A GPON can replace existing copper-wire cabling and deliver higher data speeds with greater reliability.
Can we convert EPON to GPON?
In GPON both downstream and upstream line rates are 2.5Gbps and 1.25Gbps respectively and its splitting Ratio is 1:128. GPON converting the Ethernet packets to GEM frames….GPON VS EPON.
| GPON | EPON | |
|---|---|---|
| Application mode | Multi service /FTTx | Pure data Service |
| Broadband Efficiency | 92% | 71% |
What is the advantage of GPON?
GPON offers higher bandwidth delivery – it has a 2.4 Gbps downstream capacity and a 1.2 Gbps upstream capacity. It uses larger, variable length packets to transmit data and employs frame segmentation to give higher quality for voice and video traffic.
Is GPON compatible with EPON?
Overview of xPON ONU xPON ONU is an optical network unit that supports both EPON IEEE 802.3ah standard and GPON ITU-TG. 984. x standard, which means it can be used in both EPON and GPON networks.
Is EPON symmetrical?
GPON Limitations Not truly symmetrical. GPON has slower upload speeds. Difficult to update and scale if your business needs more bandwidth in the future.
Is GPON better than FTTH?
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). …
Is GPON a fiber?
GPON networks are currently the leading form of Passive Optical Networks (PONs), and offer up to a 1:64 ratio on a single optical fiber, meaning, a single fiber from the OLT can deliver video, data and voice signals to up to 64 end users (or residences).
Is GPON shared bandwidth?
For example, GPON allows 2,300 Mbits/sec (i.e. 2.5-Gbits/sec line rate x efficiency) of bandwidth to be shared by 64 customers, or about 35 Mbits/sec per customer. The higher bandwidth and split ratio makes GPON technology particularly suitable for multi-tenant or multi-dwelling buildings.
What is the difference between GPON and 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 the difference between GPON and EPON?
GPON stands for Gigabit Ethernet passive optical network. GPON uses ATM for voice, Ethernet for data, and proprietary encapsulation for voice. It offers faster Gbps than EPON on downstream and upstream bandwidths. These sounds similar, but there are key differences.
What are the benefits of using EPON?
The use of EPON allows carriers to eliminate complex and expensive ATM and Sonet elements and to simplify their networks, thereby lowering costs to subscribers. Currently, EPON equipment costs are approximately 10 percent of the costs of GPON equipment, and EPON equipment is rapidly becoming cost-competitive with VDSL.
What is the cost advantage of GPON?
GPON provides multiple selectivities, but its cost advantage is not obvious. The maximum physical distance that a GPON system can support is 20 km when the optical splitting ratio is 1:16. When the optical splitting ratio is 1: 32, the maximum physical distance should be 10 km.
What is the difference between GPON and providers’ split ratios?
Providers can define the split ratio according to the services and bandwidth they want to support. In contrast, GPON defines an upper limit on split ratio: It can support 128 but typically it is 64. There are several common split ratios of GPON – 1:32, 1:64, or 1:128.
