To support Ethernet transport applications, network operators need carrier-grade 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.
