Features
ITU-T G.984.x
Meets the requirements of ITU-T G.984.1, ITU-T G.984.2, ITU-T G.984.3 and ITU-T G.984.4.
Class B+ SFP High Quality Optics
Class B+ optics for transmitting at 2.488Gbps in downstream and 1.244Gbps in upstream. Fast electronics allow standard’s minimum size preambles reducing line overhead. Can be upgraded to near-future C optics without changing the system configuration. Allows measuring the power received from each ONT.
Up to 128 ONTs and 512 Alloc-IDs
Supports up to 128 ONTs and 512 Alloc-IDs per GPON channel, maximizing the subscribers per PON according to the standard.
Fully featured ONT OMCI stack
Implements all the OMCI stack and VLAN tagging specified in the GPON standard and full management of the ONT through Operation Management Control Interface (OMCI) protocol.
AES Encryption and FEC encoding
Supports AES encryption for downstream communications. FEC supported in both downstream and upstream signaling: increasing optical budget.
10G Flexible transport interconnection
Telnet’s GPON-OLT Line cards have two different transport interfaces (Configurable in independent and redundant fashion):
Backplane XAUI connection to other TeraSAEs transport cards (Routing, aggregation, XPonder)
Front XFP 10G Ethernet LAN interface
TeraSAE Chassis
The GPON-OLT Module is integrated in the high performance TeraSAE chassis, allowing it to be installed with other passive and active equipment, facilitating the installation and optimizing the space in central.
VPON Module
Demoduler module with optional EDFA that converts RF analogic signal into optical 1550nm signal for GPON.

GPON OLT
The Telnet GPON-OLT is a OLT module for Gigabit Ethernet Passive Networks (GPON). It supports up to 128 ONTs and up to 512 Alloc-ID per GPON cannel, allowing to cover residential areas with GPON service.
All OLT of Telnet Redes Inteligentes’ family fully comply the ITU-T G.984.3 and ITU-T G.984.4 specification, which makes them totally interoperable with any ONT in the market, supporting full management of ONTs via OMCI protocol and VLAN tagging.
The Telnet Redes Inteligentes GPON-OLT supports the TeraSAE chassis, a high performance chassis for central equipment with redundant power supply, an integrated control console and high efficiency cooling fans and supporting up to 14 GPON-OLT line cards.
Its double transport interface allows Telnet’s GPON-OLT to be used in different scenarios and environments: From complex transport schemes with multiple cards to simple (And “const effective”) scenarios where the GPON-OLT can be directly connected to a 10G Router, not needing any extra aggregation card. Automatic redundant configuration also available for safe environment scenarios.
Level 2 Service Transportation with QinQ and Priority VLAN Tagging
In a scenario where an integrator deploys its own GPON network over a population of possible subscribers for, it is desirable to be able to rent the access to the GPON carrier service to one or more Internet Service Providers (ISP). Then two roles are defined: Data Carrier (The GPON network) and ISP (Providing service to selected users over the GPON network)
As a consequence, ISPs would require a level 2 access connection in order to provide different services to the residential subscribers: Voice Over IP, Video On Demand, Broadband Internet Access, etc. (Always keeping the services independent from different vendor’s hardware )
ISPs also require the possibility to offer professional connectivity services to companies located in the GPON coverage area. i.e. Local delegations of a corporation that wants to have its own LAN (Local Area Network) connected to headquarters LAN, being able to transparently sharing data and services at LAN line rates.
In this scenario, it is required to provide to the ISPs a way to offer a wide range of services in an efficient and standard way: From L3 residential services to L2 tunneling between networks To achieve this goal it’s been proposed a combination of VLAN/QinQ architecture and commutation schemas fully based on the Ethernet standard and the QinQ double tagging that extends the IEEE 802.1QinQ amendment to the Ethernet standard.
Following this VLAN architecture, a pair of Client-VLAN and Service-VLAN is required to define residential services. For Premium Professional services (Like LAN L2 Tunneling), additional Client-VLANs and Service-VLANs reservations by the ISP will be required for each customer.
This solution offers two main advantages to the ISPs.
Allows the ISPs to provide all kind of level 2 and level 3 services, such us DHCP, IP, PPPoE, etc.
Independence of the Router Gateway used by the ISP, easing the access to the GPON and lowering the access cost to the network by using existing routing hardware.
