DWDM MUX DEMUX

1 Overview
Hby-cwdm multiplexer is a passive optical multiplexing device
CWDM – sparse wavelength division
（Multiplexing）。 Multiplexers allow you to organize transport channels for various services
(Fast Ethernet, STM-1 / 4 / 16 / 64, Gigabit Ethernet, fibre channel, 10 Gigabit Ethernet) or
Two optical cables. The number of channels depends on the modification of the multiplexer
From 2 to 16.
CWDM HBY multiplexer with express port for
Transmit additional services in the wavelength range of 1270 nm to 1610 nm
Except for the wavelengths involved in the transmission of main services. To express port
Terminal equipment and CWDM / OADM multiplexer can be connected at the same time.
Hby-cwdm-oadm multiplexer is a passive optical device
CWDM multiplexing with selection function - insert one or more wavelengths from the total wavelength
OADM – optical add drop multiplexer.
The multiplexer allows insertion, selection and transmission
Various services (Fast Ethernet, STM-1 / 4 / 16 / 64, Gigabit Ethernet, fibre channel, 10 Gigabit)
Ethernet) consists of one or two optical cables. The number of descent channels added depends on
Modification from multiplexer and from 1 to 4.
Typically, the OADM multiplexer is installed in the notch of the transmission node
Optical cable, so the OADM multiplexer has two line ports connected to the wals
– input and output and select Insert ports to extract the required services.
There are two types of OADM multiplexers: type 1 - select only from the input port
Required service, type 2 – select the required service and add it to the released wavelength
Other services, send the remaining threads to the output port.

CWDM chooses HBY, excellent performance and reliable quality.
Scope of application: CWDM system, CATV system, network upgrade, MAN access layer, telecommunication, enterprise network, etc.
Working wavelength: 1270~1610nm O, E, S+C+L band
Channel spacing: 20nm----The crosstalk between channels is small, and the isolation is large. (Channel spacing refers to the difference between the nominal carrier frequencies of two adjacent channels and can be used to prevent inter-channel interference.)
Insertion loss:

Do you know about micro plc splitter?
PLC optical splitter can evenly divide one input optical signal into multiple output optical signals. It is one of the most important passive components in optical fiber links and plays an important role in application technologies such as EPON, GPON and BPON. PLC optical splitter has a variety of split ratios, the most common are 1:8, 1:16, 1:32, 1:64, 2:8, 2:16, 2:32 and 2:64.
The Micro PLC Optical Splitter has a compact stainless steel tube package, and the connectors are commonly used in SC, LC, FC and ST types. Because of its ultra-small size, the miniature modular PLC optical splitter can be installed in the optical cable splice box and module box.
The miniature optical splitter has the characteristics of small size, low insertion loss, low polarization-related loss, high return loss, etc. The size is small and compact, and the input end can lead out Φ0.25mm pigtail or Φ0.9mm pigtail, which is convenient for application. Ideal for small size applications. Easy to install and maintain, suitable for direct application under various engineering construction conditions.

100G DWDM MUX&DEMUX Module
HBY’s premium DWDM Mux/Demux devices reduce large quantities of individual LC fiber patch cables, allowing for a more cost-effective and clutter free networking environment. Dense Wavelength-Division Multiplexers (DWDM) are capable of combining up to 40 unique wavelengths for propagation over a single duplex LC fiber cable. DWDM mux/demux units are completely passive devices, and require zero maintenance, upgrades, or electricity to function properly. Pair these premium DWDM units with OptoSpan specialty fiber cables and high performance optical transceivers for a complete low-cost networking solution.
