DWDM Mux / Demux device without the need of temperature control

AAWG

ATHERMAL ARRAYEDWAVEGUIDE GRATINGAWG (Arrayed Waveguide Gratings) multi/de-multiplexer combines and splits
optical signals of different wavelengths, commonly used in WDM system.

Senko offers Athermal AWG (AAWG).
It is the integrated Optical circuit built
by Polymer approach (Silica on Siliconsubstrate), providing more stable reliability
performance.

Temperature
insensitive-40°C ~ +85°C

FEATURES• Excellent Optical Performance• High Channel Counts (Up to 48Ch)• Temperature insensitive (-40°C ~ +85°C)• High Reliability

ATHERMAL ARRAYEDWAVEGUIDE GRATING

Specifications of 16-48ch Gaussian Athermal AWG Module
As the 5G rollout begins, there will be ahuge increase in demand of fibers and/or wavelengths to support front haul
CPRI traffic.
Maintaining current C-RAN(Centralized-Remote Access Network)
topology, it is the simplest way toupgrade the front haul network byadding more wavelengths.
The fiber distance of a front haul fromBBU to RRH is typically < 20km.
The more complicated the network
becomes, the more challenging itbecomes to meet loss budget with20km fiber reach, compensating losses
from WDM filters, switches, fibers andconnectors, etc. Especially loss fromWDM trunk becomes critical as it affects
multiple 5G Cells significantly.
Future path
Existing DWDM filter technology does
not satisfy upcoming 5G front hauldemand for 2 reasons.
High losses and narrow operating
temperature range.
On the other hands, Athermal AWG
resolves the issues.
Gaussian 40Ch AAWG saves at least 6dB
in link budget for a pair of MUX/DEMUX
and has wider operating temperature
range -40°C ~ +85°C .
