25G demand is increasing day by day
• Operators are evolving their access networks and migrating to 25Gbit/s line rates
between access and aggregation nodes to future-proof their networks and reduce
cost per bit
• Furthermore, limited fiber resources are driving the demand for DWDM-based
solutions and therefore for colored optical transceivers
• Operators need to find a solution that enables a smooth and cost-efficient upgrade
to 25Gbit/s DWDM with minimal operational complexity and maximum reuse of
existing 10Gbit/s-based infrastructure
Boost capacity with cost-efficient 25Gbit/s DWDM pluggable optical transceivers

AccessWave25™
Our AccessWave25™ enables cost-efficient 25Gbit/s direct
detection PAM4 DWDM connectivity with up to 40km reach
from any device with an SFP28 port
AccessWave25™ reduces capex and opex through:
• DWDM tunable optics with extended reach
• G.metro wavelength auto-tuning
• SFP28 form factor
• I-temp hardened design
• Host-independent operation
• Compatibility with existing 10Gbit/s infrastructure
Designed to easily and cost-efficiently upgrade access networks to 25Gbit/s

Patent-pending innovation
• With scaling rules equivalent to 10Gbit/s technology, AccessWave25™ can be used
over existing 10Gbit/s-based network infrastructure and is host-agnostic in any
SFP28 port. No need to tear out equipment to upgrade your network
• The ADVA turnkey FSP 3000 solution for passive optical access offers the highest
performance at minimum cost
• The combination of C-band operation and 25Gbit/s bandwidth typically limits the
maximum reach to a few kilometers (dispersion limited)
• With patent-pending technology innovation, the ADVA AcessWave25™ enables
25Gbit/s DWDM links with up to 40km reach without dispersion compensation or
optical amplification (G.652 fiber)
