Professional Grade Optical Multiplexer CWDM Filter 1x2 Fiber
Optical Bare Cwdm Multiplexer with Steel Tube for CWDM Optical
Transmission Setups
HJY offers a full range of CWDM Mux-Demux and Optical Add Drop
Multiplexer (OADM) units to suit all kinds applications and network
solutions. Some most common ones are: Gigabit & 10G Ethernet,
SDH/SONET, ATM, ESCON, Fibre Channel, FTTx and CATV.
1x2 CWDM Devices are based on thin film filter technology. CWDM
technology provides the flexibility to increase capacity of
existing fiber infrastructure by enabling multiple channels
(wavelengths) over the same fiber cabling. Each channel carries
data independently from each other, allowing network designers to
transport different data rates and protocols for different
customers or applications.

Networking System utilizes thin film coating technology and
proprietary design of non-flux metal bonding micro optics
packaging. It provides low insertion loss, high channel isolation,
wide pass band, low temperature sensitivity and epoxy free optical
path.
1x2 CWDM Fitler Deivce Optical Components with small size in Glass
tube or Stainless Steel Tube, Its will save much space for customer
applications.
