EAR Series Two-way EDFA

Two-way Multiport EDFAs for FTTx Networks

IPG Photonics’ EAR Series two-way EDFA is a novel approach enabling two-way RF service delivery as well as leveraging the capability and capacity of the fiber optic media by supporting many other potential wavelengths in the future. EPON and GPON standards accommodate RF video delivery using a 1550 nm wavelength overlay. In addition, the Society of Cable Telecommunications Engineers (SCTE) has developed RFoG standards to specify the requirements to support two-way RF delivery over FTTH networks. The RFoG standards have been developed so that two-way RF services can co-exist on the same EPON and GPON networks.
