AEPONYX WDM-PON Solutions For
AEPONYX is a global WDM-PON technology provider that enablies fiber optic network operators to fully virtualize their cloud infrastructures.
We provide - and stand behind - a full array of products and solutions to help fiber optic network operators take advantage of dense wavelength division multiplexing technology (DWDM).
On the WDM-PON front, our AEPON solution product family includes the AEPONYX Colormux™, the Colornode™ and the Omnicolor SFPs™'s. AEPONYX stands behind active Ethernet PON, a fully standalone non-proprietary WDM-PON solution strictly composed of 2.5 gigabit per second SFPs and passive multiplexers.
Our DWDM products include the AEPONYX DWDM Muxpanel™ as well as a complete linup of SFP+'s and XFPs.
The AEPONYX solutions are plug and play, entirely passive and backward compatible with all existing SFP-based equipment.
This solution enables 40 channels of 1, 2.5, 10 or 100 Gbps to share a pair of fiber and supports distances of up to 80 km.
Active Ethernet, when provisioned over optical fiber, means dedicating one or two strands of optical fiber to each customer.
Active Ethernet provides a 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, i.e. 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. The broadcasted downlink in a GPON network is 2.4 Gbps and the TDMA uplink is 1.2 Gbps shared among 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 (CPE) 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.
These days, GPON and EPON are 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 allow 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 - a method not used in WDM-PON technology. Active Ethernet has to be built using the same topology and cost inefficiencies already present in the copper telephone network. As a consequence, traditional active Ethernet over a fiber optic access network requires cables with as many strands as there are customers or - another possibility - 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 while also benefiting from the efficiencies of passive optical network topologies. Because all components of WDM-PON technology can take advantage 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 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.
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 any need for active electronics shared by multiple tenants and their associated requirements for backup power. AEPONYX even enables buildings to be served with dual-homed 'east-west' redundant feeds which is as trivial as putting a 1x2 coupler in front of the Colornode™.
Unlike GPON which shares bandwidth of 2.4 Gbps downstream and 1.2 Gbps upstream in the time domain, AEPONYX provides WDM-PON technology where each of the 40 circuits gets a dedicated channel capacity. As an example, this means an aggregate of 100 gigabits per second is shared among 40 customers. This is 40 X more capacity than GPON from the network to users' direction and 80 X more capacity than GPON from users'direction to 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 provide connectivity to 32 different customers in the field.
