Describe Product

This product is FTTH (Fiber to the Home) optical receiver, with low power optical receiving, which can satisfy the demand of FTTH CATV receiving. It can separately and effectively receive 1550nm wavelength of CATV signal, with optical isolator, to satisfy the demand of only allowing 1550 wavelength received, and filtering out other wavelength optical signals.

The product is compact, easy installation, and an ideal product for FTTH CATV network.
