To support Ethernet transport applications, network operators need carriergrade solutions to provide enhanced Ethernet operations, administration and maintenance (OAM) capabilities in the access network while reducing OPEX and CAPEX. This white paper discusses how the Nokia Layer 2 OAM Smart SFPs support a wide variety of application scenarios and provide network demarcation plus MEF CE 2.0 Ethernet OAM cost-effectively and reliably in an SFP form-factor.
