Tip of the Week – FTTH Deployment
Are you planning a fiber to the home deployment (FTTH)?
Have you considered technology alternatives to typical GPON including WDM-PON?
WDM-PON uses simple passive multiplexers at the CO location and field distribution sites to provide each customer with a dedicated DWDM wavelength. This system has many advantages including simple upgrades from 10/100 to 1GE to 10GigE and even 100GigE to each customer (or a mixture of all).
Here are a few advantages and disadvantages of WDM PON deployment:
- Simple technology well known to many companies.
- Low learning curve.
- Simple to install and maintain.
- Supports a wide range of data rates from 10/100mbps to 100Gbps on any channel.
- Simple to upgrade to higher data rates, just change the DWDM transceivers.
- Each WDM Channel is protocol transparent and independent of the other channels.
- Can be relatively less costly to deploy and maintain.
- Can be deployed on 2 or 1 fiber strands.
- Symmetrical data speeds.
- Limited by DWDM transceiver optical budge, fiber link loss and mux insertion loss. However some designs can use optical amplifiers.
- Channel tunable DWDM transceivers can be expensive. Lower prices are available for quantity purchases of fixed channel transceivers.
