•
3R regeneration (re-timing, re-shaping, re-transmit) maintains performance over extended
distances.
•
Two latency modes:
Low latency (<200 ns) with full 3R regeneration (re-timing, re-shaping, re-transmit). This mode
is typically used in multi-hop configurations and supports a large number of SFT-10G16
regenerations.
Ultra-low latency (< 5 ns) for time-sensitive applications. 2R regeneration (re-shaping and
re-transmit). This mode is limited to two SFT-10G16 regenerations and is typically used in
point-to-point or low-hop count configurations.
•
Loopback support on all trunk and client interfaces for transmission testing.
•
Passive 1+1 optical protection provided on client and trunk interfaces using Cyan Transport
Protection Module (TPM) and Optical Protection Switch (OPS) equipment.
The graphic below shows the SFT-10G16 block diagram.
