诺基亚FELT-B 3FE69486AB

The FELT-B:
• can be used in the following subracks:
• a 7302 ISAM subrack (with NANT-E only)
• a 7330 ISAM FTTN subrack (with NANT-E only)
• a 7360 ISAM FX-4, 7360 ISAM FX-8 or 7360 ISAM FX-16 subrack
• supports the following Small Form Pluggable (SFP) optical modules:
• standard SFP at FE/GE/2.5G rates
• compact SFP at FE/GE rates
• SFP+ at 10G rate
• supports the following network synchronization options:
• Synchronous Ethernet
Input: Extracts the network clock from any two (programmable) P2P ports and pass 
the selected clock to the BITS OUT interface so it can be used by the NT card to 
synchronize the whole system 
Output: Distributes the Network Timing Reference, derived from the NT board, to all 
Ethernet ports of the card 
• IEEE 1588v2 ToD (Time of Day)
Supports both IEEE 1588v2 TC (Transparent Clock) (input/output)
Supports IEEE 1588v2 BC (Boundary Clock) towards all its Ethernet ports (output 
only) in conjunction with an NT board variant supporting IEEE 1588 ToD 
• can be used in the following operation conditions:
• -5°C to +45°C ambient temperature range, in CO environment with multiple 
7302 ISAM subracks and 7360 ISAM FX-16 subracks
• -40°C to +65°C ambient temperature range, when used in single 7302 ISAM 
subracks and 7360 ISAM FX-16 subracks
• -40°C to +65°C ambient temperature range, when used in stand-alone 
7330 ISAM FTTN subracks, 7360 ISAM FX-8 subracks and 7360 ISAM FX-4 
subracks
• can be hot inserted or extracted without service interruption
• meets ETSI/MII and ANSI specifications
• is compliant to the regulations of Restriction of Hazardous Substances (RoHS) 
and Waste Electrical and Electronic Equipment (WEEE)
• is compliant to safety standards IEC/EN 62368-1, AS/NAZ 62368-1, and 
UL 60950-1, provided the board is installed, maintained and used according the 
relevant installation instructions
