What is Cisco GPON?
The telecommunications industry, led by Verizon, is offering Gigabit Passive Optical Network or GPON technology, as an alternative to Ethernet switching in campus networking. GPON is the core underpinning of Verizon’s FiOS (Fiber Optic Service), a consumer-oriented triple play service.
What does GPON mean in router?
Gigabit Ethernet passive optical network
GPON stands for Gigabit Ethernet passive optical network (PON). GPON uses Asynchronous Transfer Mode (ATM) for voice, Ethernet for data, and proprietary encapsulation for voice. This means that it uses fixed-sized cells instead of variably sized packets of data.
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 difference between GPON and EPON?
GPON and EPON Differences GPON provides three Layer 2 networks: ATM for voice, Ethernet for data, and proprietary encapsulation for voice. EPON, on the other hand, employs a single Layer 2 network that uses IP to carry data, voice, and video. A multiprotocol transport solution supports the GPON structure (Figure 1) .
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 the maximum logical reach in GPON?
The maximum logical reach in GPON is defined as 60 Kilometres.
Is a GPON terminal a modem?
Technically speaking, an Optical Network Terminal (ONT) is not a modem. However, for fiber-optic Internet, an ONT acts similar to a modem because it communicates with an Internet service provider (ISP). An optical network terminal (ONT) is like a modem, but for fiber-optic networks.
Can GPON use EPON?
GPON is purposely built as a point-to-mulitpoint protocol. EPON calls upon Ethernet to function the same as GPON. In other words, GPON is efficient and EPON is not.
Is GPON better than FTTH?
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 is the speed of GPON?
2.5 Gbits/sec.
Using recent innovations in optical transceiver products, Gigabit PON (GPON) delivers twice the bandwidth of EPON at its full speed of 2.5 Gbits/sec.
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% |
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).
What kind of access scenarios does Cisco GPON support?
Cisco ME Series products support any fiber-based (FTTx) access scenarios, including Fiber To The Home (FTTH), Fiber To The Building (FTTB), Fiber To The Curb (FTTC), Fiber To The cell (FTTc), and Fiber To The business (FTTb). Figure 1 illustrates the Cisco GPON solution. Figure 1.
What’s the difference between GPON and Ethernet switching?
GPON is an alternative to Ethernet switching in campus networking. GPON replaces the traditional three-tier Ethernet design with a two-tier optic network by eliminating access and distribution Ethernet switches with passive optical devices.
Is the Cisco GPON SFP compatible with Olt?
The Cisco GPON SFPs are supported by the ME 4600 Series OLT devices. For more details, refer to the document “ Cisco Gigabit Ethernet Compatibility Matrix ” and ME 4600 Series datasheet.
What are the optical parameters for a GPON transceiver?
Table 2 describes the optical parameters for the GPON class C+ SFP OLT transceiver module. Table 2. Optical Parameters for GPON Class C+ SFP OLT Transceiver Module Operating temperature range (see Table 3): ● Commercial temperature range (COM): 0 to 70°C (32 to 158°F) ● Industrial temperature range (IND): -40 to 85°C (-40 to 185°F)
