Overview of GPON Technology

The most important aspect of PON architecture is its simplicity. The Optical Line Terminal (OLT) is the main element of the network and it is usually placed in the Local Exchange or a NOC of a township. Optical Network Units ONUs serves as an interface to the network and are deployed on a customer’s side. ONUs are connected to the OLT by means of optical fiber and no active elements are present in the link. A single ONU can serve as point of access for one (Fiber to the Home) or multiple (Fiber to the Block or Curb) customers and can be deployed either at customer’s premises (Fiber to the Home or Block) or on the street in a cabinet (Fiber to the Curb).

GPON STANDARDS

A big advantage of GPON over other schemes is that it interfaces to all the main services are provided and in GFP enabled networks, packets belonging to different protocols can be transmitted in their native formats.

As in modern networks the security of transmitted data is a key issue. A sophisticated mechanism based on Advanced Encryption Standard and a complex exchange of unique keys is built into the GPON architecture.

Bandwidth rate limiting is done on an ONT port level.

Internet user shall be rate limited corresponding to the connection speed subscriber with the ISP, but the down side is, if the customer upgrade his/her connection speed, for ex 512Kbps to 1Mbps, it has to be coordinated with the our team to allow the rate limiting to be increased on the ONT port. Voice requires a maximum of 64Kbps. IPTV bandwidth requirement is set to a standard 6Mbps which is in accordance with the service provider standards. With all the triple play services, an average bandwidth of 20Mbps is utilized per ONU.

PLATFORM MANAGEMENT MODULE (PMM)

The T7 chassis-based OLT includes one slot for the Platform

Management Module (PMM), which is the primary interface for

external management applications. The PMM utilizes XML and

SNMP (v2c or v3) for in-band or out-of-band communication with

the TRIDENT7 Element Management Suite (T7 EMS) or other

network management platforms in order to coordinate the operation

of other modules in the OLT and its subtended ONTs. A command-

line interface may be accessed with Telnet, SSH, and local craft

port. The PMM supports programmable input/output connections for

central office and housekeeping functions. The functionality of the

PMM in integrated within the Compact OLT.

PLATFORM SWITCH MODULES (PSM)

The T7 chassis-based OLT includes two slots for

redundant Platform Switch Modules (PSMs), which aggregate

all (non-RF) services traffic of subtended ONTs. These modules

utilize IEEE Spanning Tree protocols and Link Aggregation over

Ethernet links in multiple common topologies to provide resilient

interconnection with the distribution network.

PLATFORM INTERFACE MODULES(PIM)

The T7 chassis-based OLT includes eighteen

(18) slots for Platform Interface Modules (PIMs),

which may be of one type or mixed PIM models.

Each PIM provides SFP-based ports for FTTP

connections to ONTs and other customer premise

equipment through the Optical Distribution Network

(ODN).

The Customer Service Excellence Standard aims to bring professional, high-level customer service concepts into common currency with front-line public services by offering a unique improvement tool to help those delivering public services put their customers at the core of what they do.

Customer Service Excellence

• Customer Insight• Customer Segmentation• Customer Journey• Access Channels• Drivers of Satisfaction

Key Concept

CSE is a driver of continuous improvement

CSE gives you insight into your own organisation (how customer focused are you)

CSE gives improved understanding of customer issues (by developing customer insight)

CSE improves relationship with and satisfaction of customers

CSE is a skills development tool building real team spirit and morale

CSE is an independent validation of achievement in customer service

Operations & Maintenance

The operations & maintenance is a critical part for the sustenance of a GPON-FTTx network. O&M requires a dedicated team 24/7 to support the services running on a GPON transport. Vendor O&M teams at our pre-existing customers who have deployed GPON-FTTx rigorously follow ITIL best practices to ensure 99.95% of uptime.
