Which GPON OLT is best?
Huawei holds the leading position in the GPON market as it has the most comprehensive array of OLT and ONT products that support GPON and 10G-PON technologies. Huawei’s GPON OLT and ONT products are the most popular GPON products in the market, primarily because of their superior quality and brand value.
What is Type B protection GPON?
Type B protection in GPON FTTH access network, the OLT sends and receives traffic through the standby GPON ports to overcome GPON-port failure. Source publication. +5.
What is the difference between GPON OLT and EPON OLT?
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) .
Which is better GPON or EPON?
EPON is a native Ethernet solution that leverages Ethernet protocol, and GPON leverages SONET/ SDH and Generic Framing Protocol (GFP) to transport Ethernet. Thus for layering comparison, EPON is better than GPON and for service, GPON is better.
Can I use GPON instead of 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.
What is GPON vs 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.
How many PON ports are in OLT?
GPON Optical Line Terminal (OLT)
| Name | PON line ports | Uplink ports |
|---|---|---|
| OLT LTP-4X | 4 | 4 combo ports of 10/100/1000Base-T/1000Base-X 2 ports 10GBase-X (SFP+) |
| OLT LTP-8X | 8 | 4 ports of 10/100/1000Base-T ports, 4 combo ports of 10/100/1000Base-T/1000Base-X 2 ports of 10GBase-X (SFP+) |
What is GEM port in GPON?
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.
How many ONT can be connected to OLT?
128 ONTs
The OLT contains a central processing unit (CPU), passive optical network cards, a gateway router (GWR) and a voice gateway (VGW) uplink cards. It can transmit a data signal to users at 1490 nanometers (nm). That signal can serve up to 128 ONTs at a range of up to 12.5 miles by using optical splitters.
