Applications
- Metropolitan access and aggregation network: connects metropolitan aggregation nodes and access nodes within a 40 km range.
- Long distance links with tight fiber optic resources: When the fiber optic pipeline is full and new fibers cannot be laid, but a 40 km gigabit link needs to be achieved.
- Enterprise/Campus Backbone Network Interconnection: Connecting different plots or buildings in large parks that are 40 km apart.
- FTTx/access network: used for long-distance connection between the central office (OLT) and the user side (ONU).
Standards
- Compliant with SFP MSA
- Compliant with SFF-8472
- Compatible with IEEE802.3ah 2004
