AEPONYX WDM-PON Solutions Features & Benefits

Dense Wavelength Division Multiplexing (DWDM) Passive Optical Network (PON) Solutions composed of small form pluggable transceivers (SFPs) and passive multiplexers

AEPONYX is a global WDM-PON technology provider enabling fiber optic network operators to fully virtualize their cloud infrastructures.  

We stand behind a full array of products and solutions enabling fiber optic network operators to take advantage of dense wavelength division multiplexing technology (DWDM).  

On the WDM-PON front, the products as part of our AEPON solution include the AEPONYX Colormux™, the Colornode™ and the Omnicolor SFPs™'s. 

On the DWDM front our products include the AEPONYX DWDM Muxpanel™ as well as a complete linup of SFP+'s and XFPs.

AEPONYX stands behind Active Ethernet PON, which is non-proprietary WDM-PON Solution that is fully standalone strictly composed of 2.5 gigabit per second SFPs and passive multiplexers.  

An Active Ethernet Passive Optical Network (AEPON™) can be implemented in as little as 5 easy steps: 

  1. Install a first AEPONYX™ Omnicolor™ Small Form Pluggable (SFP) transceiver in an available SFP interface of a service provider switch or router;
  2. Connect an available channel AEPONYX™ CO Colorcord™ between the Omnicolor™ SFP and the matching channel port of a fully passive AEPONYX™ Colormux™;
  3. Connect the common port of an AEPONYX™ Colornode™ to the common port the Colormux™, via a single fiber connection that can be up to 60 km in length;
  4. Install a second AEPONYX™ Omnicolor™ Small Form Pluggable (SFP) transceiver in an available SFP interface of a customer premise equipment (CPE)
  5. Connect an AEPONYX™ CL Colorcord™ of the same channel than the CO Colorcord™ between the CPE Omnicolor™ SFP to the downlink of the Colornode™. This would be done in the same manner that a CPE would be connected to the client port of a GPON power splitter, albeit with the variant of simply needing to choose the Colorcord™ corresponding to the proper WDM-PON channel.

The AEPONYX WDM-PON Solution is plug and play, entirely passive and backwards compatible with all existing SFP-based equipment.  

The solution enables 40 channels of 2.5 Gbps to share a single fiber and supports distances of up to 60 km.

Active Ethernet Dedicated capacity without need to allocate a dedicated fiber to each customer

Active Ethernet when provisioned over optical fiber means dedicating one or two strands of optical fiber to each customer.

Active Ethernet provides better quality of service than Ethernet PON or Gigabit PON technologies (EPON, GPON). With Active Ethernet, bandwidth does not have to be shared in time between multiple users.

Active Ethernet networks can be provisioned wirespeed, where the uplink capacity exceeds the capacity of all downlinks, under the assumption that all circuits are used at full speed simultaneously.

It is not possible to provision GPON and EPON networks wirespeed, as those technologies are based on a single wavelength broadcasted to all users behind the same convergence point power splitter.

Further, with GPON and EPON, the service provided to end-users is usually very assymetrical.  For instance, in a GPON network, the broadcasted downlink is 2.4 Gbps and the TDMA uplink is 1.2 Gbps shared amongst all users of a local converence point.  There is only one return wavelength which has to be alloted one user at a time.

The customer premise equipment is controlled by the central office equipment to discriminate which packets are destined to it and thus presented to the end-user. In that sense, GPON and EPON technologies are inherently insecure and communications should ideally be encrypted.

GPON and EPON are used today to dramatically lower the costs of operating telecom access networks, as these technologies allow for the fiber optic access network, to be built using distributed local convergence points of 32 customers sharing the same feeder fiber.  GPON and EPON allows for the fiber optic access network to remains entirely passive for 20+ km, meaning that no element in the access network requires powering of any kind.

GPON and EPON technologies are widely recognized for being far more cost effective than the traditional way of building Active Ethernet fiber optic access network, which absent of WDM-PON technology, has to be built using the same topology and cost inefficiencies built into the copper telephone network.  Traditional Active Ethernet over a fiber optic access network requires cables with as many strands as there are customers or in the alternative, the servicing of customers from many locations with powered active electronics in the field.

With WDM-PON technology, it is possible to build an Active Ethernet Network, with attributes of wirespeed aggregation and dedicated capacity per end-user, but also with the efficiencies of passive optical network topologies.  Further, with WDM-PON technology, because all components benefit from low insertion losses, it is possible to deploy at even greater distance than that possible with EPON or GPON, even with 40 circuits sharing the same single optical fiber.  

This is what AEPONYX refers to as AEPON™, or Active Ethernet PON (Passive Optical Network).

AEPON™ technology is based on well understood dense wavelength division multiplexing passive optical networks (DWDM-PON) theory and practice.

In a WDM-PON network, 1:32 power splitters found in EPON or GPON networks are ideally replaced by an AEPONYX 40 channels Colornode™ acting as a WDM-PON remote node.

The behavior of the AEPONYX Colornode™ is not that of sending the same signal down 32 paths, but that of routing only two of the 80 wavelengths (a pair of C+L lambdas) down an output dedicated to a customer.

The technology behind AEPONYX Colornodes™ is known as Cyclic Athermal Arrayed Waveguide Gratings (AAWG's) and is also found in long-haul transmission networks, but modified for the needs of outdoor (Athermalized) single fiber (Cyclic) access networks.

The inherent Cyclic properties of AEPONYX Colornodes™ which are made with premium-grade outside plant rated AAWGs, makes it possible for 40 lambdas in the C band as well as 40 lambdas in the L band, to share a single fiber.

This makes it possible to achieve 40 full-duplex channels leveraging all 80 lambdas on a single fiber.

AEPONYX promotes the upgrade of EPON and GPON with its AEPON™ Solutions enabling 1:40 splitting ratios at local convergence points that are centralized, by simply removing the 1:32 power splitters and replacing them with 40-channels AEPONYX Colornodes™.

With AEPON™, it is possible to provision 40 circuits onto a single fiber over distances of up to 60 kilometers, allowing operators to expand their networks without need for overbuilding them.

The lambda multiplexing layer that empowers AEPON™ DWDM technology gives rise to the name of AEPONYX. In AEPONyX, the y represents an inverse lambda and the X represents the multiplexing of lambdas on a single fiber. Hence, with its AEPON™ technology deployed over a layer of Lambda multipleXing, AEPONYX conveys the meaning to its name.

Exactly like GPON or EPON are single fiber technology so is Active Ethernet PON (AEPON) from AEPONYX.  AEPONYX enables critically important single fiber operation, yet without any of the speed shortcomings of GPON or EPON.

This enables compatibility with existing pre-connectorized outside plant technology built for GPON.  This also eliminates all of the engineering, training and avoids all errors associated with building the access network for two-fiber operation to a customer location. 

Passive Optical Networking with 40 circuits onto a single fiber

By enabling 40 circuits to share a single fiber, WDM-PON enables fiber optic network operators to leverage passive optical networking.  This means that the outside plant does not consume any electricity. This also means that with WDM-PON, buildings with multiple tenants can be served without need for any active electronics shared by multiple tenants and the associated requirement for backup power.   AEPONYX even enables buildings to be served with dual homed 'east-west' redundant feeds as it is as trivial as putting a 1x2 coupler in front of the Colornode™.

100 Gigabits per second dedicated capacity per local convergence point to be equally divided amongst 40 customers

Unlike GPON which shares bandwidth of 2.4 Gbps downstream and 1.2 Gbps upstream in the time domain, AEPONYX provides WDM-PON technology wherin each of the 40 circuits get a dedicated 2.5 Gbps capacity.  This means an aggregate of 100 gigabits per second is shared amongst 40 customers. This is 40 X more capacity than GPON in the directions towards customers and 80 X more capacity than GPON in the direction of the customers towards the network.

The incremental costs to provide this much capacity compared to GPON or EPON is simply found in the use of dedicated pairs of AEPONYX Omnicolor SFPs for each circuit (on dedicated lambdas) whereas GPON or EPON use a single transceiver on the service provider switch to provided connectivity to 32 different customers in the field.
