| Salira 2500 Optical Line Terminal
Overview
The 2500 OLT is an optical transport system that connects
your high-speed long haul network to multiple Salira ONUs,
creating a point-to-multipoint network. This device, which
sits at your regional office or data center, supports up to
14 PON links—each delivering a gigabit of symmetrical
payload distributed to multiple ONUs up to 20 km away.
Key Features
Key features of the 2500 OLT include:
Support for Multiple Services
- Fast Ethernet (10/100/1000 Mbps)
- Time Division Multiplex (TDM) (DS-3, E1/T1, and STM-1/OC-3)
- Very high bit-rate DSL (VDSL)
Intelligent Resource Allocation
- Dynamic bandwidth allocation (with OLC-S)
- Oversubscription with protection for prioritized or latency-constrained
traffic
- Full QoS prioritization with differentiation between committed
rate and peak rate traffic
Flexibility and Scalability
You can configure the flexible 2500 OLT to support a variety
of geographic coverage and customer bandwidth requirements.
