Fundamentals of GPON Infrastructure Completely Single Mode fiber solution

- Multimode fiber will not support the 20-30Km reach- Multimode cannot support multiple wavelengths For upstream/downstream traffic on single filament- Multimode cannot support multiple wavelengths For upstream/downstream traffic on single filament- Single mode supports over 69Tbps of throughput, making it a ‘future proof‘ transport medium

Benefits of fiber plant vs. copper:N ibl EMI

Turn this:Into this:– Not susceptible to EMI

– Unmatched security from tampering and intrusion– Lower material and installation cost– Smaller cable footprint than a copper infrastructure

Into this:

GPON connections are all simplex SC-APC connectors

A single strand of fiber (with a 1x32 splitter) can provided up to 128 GbE end user ports

Splitters are completely passive, and able to be placed in nearly any accessible space (floor, ceiling box, closet, manholes)

Communications closets (IDF/TR) become passive spaces for the fiber splitter, or simply a fiber pass thru.

Why choose fiber?y• Superior Performance:

– Optical fiber offers far greater bandwidth and distance.– A single generation of optical fiber has outlasted and outperformed seven

generations of copper cable.• Ease of Installation:

– Optical fiber has become increasingly easier to install – while copper has b l tt ti t k ith fbecome even more complex, attempting to keep up with performance demands.

– No shielding is required to protect fiber optic cables from electromagnetic interference (EMI) or Radio Frequency Interference (RFI) and fiber optic cables are far easier to test and certify.

• Unmatched Security:– Harder to tap into than copper and not vulnerable to EMI, optical fiber is

inherently safer at keeping information securely flowing where it needs to go and not into the wrong hands.

• Easy to Upgrade:– Minimize your network downtime during expansions and upgrades, using

your existing fiber optic cable and replacing only the electronics, rather than replacing the entire infrastructure.ll i• Smaller Footprint:

– Fiber optic cables have a much smaller size and lighter weight than copper cables providing the same capacity.

Testing Simplex SM Fiber for GPONg p A standard power loss test at 1490nm (GPON Downstream) and 1550nm (RF video) is sufficient for

certifying an in building GPON fiber network New OSP cabling should be subject to OTDR testing in addition to a channel link power loss testNew OSP cabling should be subject to OTDR testing in addition to a channel link power loss test. The channel link should be tested from the fiber connecting to the OLT PON port, thru the splitter, to

the fiber connecting to the ONT The total loss permitted in a GPON network (per the ITU standards) is 8 to 28 dB including the splitter,

fiber loss over distance and combined splices (max 75dB/connector) and adapter panelsfiber loss over distance, and combined splices (max .75dB/connector) and adapter panels

Standards Bodies Limitations and SuggestionsStandards Bodies Limitations and Suggestions

33

Current Limitations in the Standards for Design/Engineeringfor Design/Engineering

BICSI TDMM provides no mention of innovative solutions, such as GPON, outside of FTTH for the residential market

Current BICSI Network LAN Layout,

Current Guidelines state the following:– A permanent WAO consists of a minimum of two copper

and/or multi-mode fiber cables– Backbone fiber cabling is limited to 2000m (6560 ft) far lessBackbone fiber cabling is limited to 2000m (6560 ft), far less

than the 20km reach of a GPON network.– Minimum IDF/TR spaces are set at 10 ft

x 8 ft, when spaces this size are no longer required

Most A&E firms will continue to design large IDF/TR closets with high volume HVAC and electrical systems to meet the legacy copper infrastructure andthe legacy copper infrastructure and Active Ethernet deployments

Without the standards bodies (BICSI, TIA, etc) providing guidelines for GPON d i d b iGPON design and best practices, creating and ‘stamping’ a design is difficult to stand behind

34

Recent Standards BodyInclusion of GPONInclusion of GPON

The current TIA/EIA 568 C draft standard provides inclusion for GPON The current TIA/EIA-568-C draft standard provides inclusion for GPON distances and the high dB loss budget of a GPON network. This standard will allow A&E firms and engineers to reference a valid standards number in their GPON specifications. (due to be voted on in Dec-2011)

Department of Defense has made many recent inclusions of GPON technology in recent solicitations, allowing for industry comment and suggestions to the

li it ti i t lsolicitation requirements language.

The most recent version of the Unified Capabilities Requirements (UCR 2008 Change 3) has specific sections devoted to GPON networks in the military.
