CWDM Filter 1x2 Fiber Optical Bare CWDM Multiplexer With Steel Tube 1270 to 1610nm for Fiber Optic Systems
1x2 CWDM Filter Devices 1270~1610nm
CWDM Filter 1x2 Fiber Optical Bare CWDM Multiplexer With Steel Tube
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.
HJY’s 3 Port Coarse wavelength division multiplexer (CWDM Single Device) 1270nm, 1290nm, 1310nm, 1330nm, 1350nm, 1370nm, 1390nm, 1410nm, 1430nm, 1450nm, 1470nm, 1490nm, 1510nm, 1530nm, 1550nm, 1570nm, 1590nm, 1610nm or 1271nm, 1291nm, 1311nm, 1331nm, 1351nm, 1371nm, 1391nm, 1411nm, 1431nm, 1451nm, 1471nm, 1491nm, 1511nm, 1531nm, 1551nm, 1571nm, 1591nm, 1611nm in Optical Transport 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.
