2.11 SFT-8 Module Transponder Module
The Cyan Z-Series 8-port SFP Transponder (SFT-8) is a multi-rate module capable of supporting drop or
insert or express traffic in the Z-Series multi-layer transport network platform.
Figure 48: SFT-8 Module
There are three primary applications for the SFT-8 module:
•
Transponding for Gigabit Ethernet and OC-3/12/48 SONET and STM-1/4/16 SDH services.
•
High-density Fibre Channel and FICON SAN support on DWDM services.
•
3R regeneration (re-timing, re-shaping, re-amplification) of up to 2.5G transmit signals.
Up to 4 2.5G Trunk Interfaces
(DWDM or CWDM SFPs)
Up to 4 2.5G Client
Interfaces (SFPs)
Up to 4 OC-3/12/48
Up to 4 STM-1/4/16
Up to 4 100FX, GbE
Up to 4 1G/2G FC, FICON
Up to 4 ESCON, ISC-1, ISC-3
Any Combination of:
Transponding
3R Regen
Up to 2.5G wavelengths
Figure 49: SFT-8 Module Trunk and Client Interfaces
SFT-8 modules provide support for both CWDM and DWDM depending on the type of SFP transceiver
configured:
•
DWDM is supported in conjunction with LAD-40/LAD-40E or
LAD-8/LAD-8i/LAD-8A/LAD-8E/LAD-8X or LAD-4/LAD-4A or LAD-2P/LAD-2G modules.
•
CWDM is supported in conjunction with LAC-8 and LAC-4P modules.
SFP Interfaces
The SFT-8 module utilizes eight SFP ports that are grouped in pairs for signal regeneration. The clock and
data recovery device supports any rate between 10 Mbps to 2.7 Gbps.
•
Line rate:
Minimum – 10 Mbps
Maximum – 2.7 Gbps
Jitter and Wander – GR-253-CORE
All of the SFT-8 ports support both copper SFP and optical SFP transceivers. In copper SFP mode, the
module supports 1000BASE-T mode.
