| What is EPON? |
 |
by Irit Gillath, Director of Product Marketing
Ethernet PON, or EPON, is based on the IEEE802.3 standard for a passive optical network (PON) and has been widely deployed, especially in the Far East. 10G EPON technology is now becoming available and is compatible with 1G-EPON. A 1G-EPON network can be incrementally upgraded to 10G-EPON, adding or replacing SFPs one at a time. |

EPON SFP
A new set of products which is basically an ONT in an SFP form factor has been released to the market attracting attention from both vendors and providers. These products incorporate the PON gateway into an SFP allowing it to be placed into any 1G fiber port on Telco Systems' demarcation product line.
What is DPoE?
DOCSIS Provisioning of EPON (DPoE) is a joint effort of operators, vendors, and suppliers to support EPON technology using existing DOCSIS-based back office systems and processes. Comcast Corporation, Time Warner Cable, and Bright House Networks under the umbrella of CableLabs have announced of the release of DPoE 1.0 specification release and continue to work on future versions.
Since the standard centers around DOCSIS, it is obviously targeting EPON deployments by MSOs. Using DPoE, MSOs can reduce the time needed to deploy EPON technology by enabling the cable provider to use their existing back office DOCSIS systems, as well as deliver high-speed Ethernet-based services.
CableLabs has organized interoperability events to enable companies to test in the EPON in their traditional ONTs as well as SFP ONTs placed into commercially available demarcation solutions. Telco Systems took part in all of these events ensuring its product interoperates with other vendors.
Telco Systems solutions
The EPON SFP combined with Telco Systems' T-Marc product line allows MSO to support service assured Ethernet services on a customer-by-customer basis, further differentiating their offering to businesses, schools, hospitals, utilities, mobile operators and government offices over an EPON network.
The T-Marc product line can provide not only Ethernet OAM capabilities, but also circuit emulation (CES) to enable MSOs to carry TDM circuits (T1/E1, DS3, OC-3/STM-1) over their fiber network to support applications like PBX backhaul or mobile backhaul that traditionally could only be supported by providers who own copper infrastructure.
Telco Systems' can provide the MSO with a complete edge solution including OLT aggregators, allowing them to benefit from MPLS scalability as well as to aggregated the CES traffic and convert it back to TDM.
