P2P (point-to-point) Ethernet applications as an alternative to PON

100-Mbps P2P (point-to-point)  Ethernet based optical access system is an alternative to EPON for access network. These networks can either use optical fibers or copper wires.

 

AS the alternative for the P2P Ethernet optical access network can be the network with individual P2P optical lines going from the central office to all clients. That means, that for each subscriber requires full-length fiber and two fibers if the links are unidirectional, also transmitter and receiver is required at both ends of the connection. This makes the cost of the network very high and this system is only used if user requires close to full capacity offered by a high-capacity Ethernet line.

Like in this case, you can use our fiber media converter series.

 

In this case media converter chassis are placed in CO side, and media converter individual cards, each working over separate fiber with SDU or MDU/MHU/MTU media converter standalone models.

 

Such applications can be or unmanaged, like in below scheme:

or, also SNMP managed one.

 

In that case you can monitor remote ends via GUI manager, like in below screenshot

For the reducing amount of fiber cables, the local switch, installed close to the subscribers, can be used. It significantly reduces the amount of wires, but on the other hand, requires electrical power for the switch and two or four more optical transceivers for linking switch to an office (four if links are unidirectional).

Single pair of non-loaded (having no special signal conditioning devices), voice-grade copper lines can be used for accessing network links. IEEE 802.3ah standard specifies the maximum data rate of 10 Mbps and maximum distance of 750m. The other two areas of this standard are:
P2P optical fiber with maximum data rate of 1 Gbps and maximum distance of 10km
P2MP (point to multi-point) optical fiber links with maximum data rate of 1 Gbps and maximum distance of 20km

 

For supporting network operation and troubleshooting purposes, the procedures of operation, administration and maintenance (OAM) are included. 100BASE-X, 1000BASE-X, 10GBASE-R, 10GBASE-W and 10GBASE-X applications are provided with the options for unidirectional transmission (in addition to OAM):

 

    • 100 and 1000 show speed in Mbps
    • 10G is meaning 10 Gbps rate
    • Letters X, R, W are refering to the physical layer families of the standard:
    • X family is used for 8B10B encoding
    • R family is used for 64B66B encoding
    • W family is referring to encapsulation of 64B66B encoded Ethernet media-access-control data within a SONET or SDH frame.

Lomoveishiy – Finland

I needed those to connect my PC on the third floor to have internet access in that room, and ISP installed their modem on the first floor only. After dropping fiber patch cables, plugged in all cables into these media converters at both sides, and link came up instantly. Was much easier than I thought!

Raymond – USA

Great experience – units worked straight out of the box – just needed plug in cables and we were done. I also like the possibility to enable jumbo frames, while we do not have a need for this feature at the current moment it’s great to have this option.
