DWDM OADM

With matching two or more OADMs and DWDM MUX/DEMUX units placed at each end of an optical link, multiple data channels can be dropped and added for specific application during transmission over the fiber trunk. 

DWDM OADM (Dense Wavelength Division Multiplexing Optical Add-Drop Multiplexer) is a highly efficient and advanced optical networking device that is widely used in the communication industry. It is designed to enhance the efficiency and speed of data transmission by using multiplexing technology, also making it possible to accommodate future upgrades. As a leading manufacturer of DWDM OADM in China, our company is committed to providing the best quality products and services at an affordable price. 

DWDM OADM is a plug-and-play device that is easy to install and operate. It requires no expertise or special tools, and it can be easily connected to existing networks. DWDM OADM supports multiple protocols such as SONET/SDH, Gigabit Ethernet, and 10G Ethernet. This feature allows it to function effectively in diverse applications, making it a versatile and reliable optical networking device.

The passive OADM modules can add or drop up to 8 data channels at any point along the trunk. They are fully compliant with CE, FCC, ISO, ITU-T G.694.2, RoHS, Telcordia GR1209 and GR1221. This page we will introduce our 100GHz DWDM OADM transmission solutions.

Product Features

4CH DWDM OADM East and West Dual-Sided

Single Mode LC UPC Dual Fiber 1U 19” Rack-mounted Casing

Insertion Loss IN-Out≤2.5dB

Insertion Loss IN-Drop≤2.0dB

Insertion Loss Add-Out≤2.0dB

Operating Wavelength: 1500nm~1600nm

This is a standard 100GHz DWDM 4CH OADM for dual fiber solution, any specific 4 wavelengths from 1525nm to 1568nm optional. Dual fiber DWDM OADM adds and drops optical signals of same wavelengths into two fibers, while letting the rest of the wavelengths bypass the line. Customized DWDM OADM perfectly tailored to meet with specific needs. Any wavelength, any connector, any housing and any special ports can be achieved.

Arkoptics strictly perform application test in end-use conditions. We inspect and ensure every fiber port to be super clean conditions, we stand behind of our quality and promise our clients a limited lifetime warranty.

DWDM OADM East and West Two-Sided

It drops one or several specific channels and adds the same channel back onto the network fiber in dual-sided transmission.

DWDM OADM East or West Single-Sided

It drops or adds one or several specific channels from the network fiber in single-sided transmission. And the dropped/added wavelengths cannot be re-used at the same local node.

Application of 4 channel DWDM OADM

4CH OADM device is used in WDM system for multiplexing and routing 4 different channels of light into or out of a single mode fiber. It’s ideal for creating DWDM bus network by connecting two OADM devices together and work with Mux Demux.

This is a two-sided 4CH DWDM OADM device. Two of them connected can set up a DWDM bus network. 4 wavelengths can be re-used in the fiber link.

How to calculate the optical loss when DWDM OADM connects between DWDM Multiplexers?

The total optical path will be facing fiber losses:

(CH20) A to B: A 3.0dB + B 2.0dB

(CH20) C to D: C2.0dB + B 3.0dB

(CH35) E to F: E 3.0dB + 2.5dB + F 3.0dB

2.5dB is the bypass loss from OADM IN to OUT

How to calculate the attenuation loss of 4CH DWDM OADM single side with 16CH DWDM Mux Demux bus network?

(CH20) A to D: A 3.2dB + D 1.6dB

(CH24) B to E: B 3.2dB + 1.0dB + E 1.6dB

(CH28) C to F: C 3.2dB + 1.0dB + 1.0dB

We are the most reliable DWDM OADM manufacture and have been supplying for large companies in Europe and USA many years.

FAQ

Q: I want to install an OADM in the splice closure we buy from you before, can you assist or provide a solution?

A: Thanks for your question, here suggest you customize the ABS pigtailed OADM, Arkoptic splice closure can be equipped with ABS OADM, but you need to use a cable tie to fix it.

Q: What do I need to consider when customize the DWDM OADM into a ABS module?

A: Fiber diameter ( 2.0mm, 0.9mm, 3.0mm ), pigtail length ( 0.25~2m, no extra charge ), with/without connectors, and ABS size (141*115*18mm, 120*80*18mm, 100*80*10mm) need to be considered.

Q: How many channels are available for DWDM OADM?

A: Following the ITU-T G.694.1 Grid, Arkoptics DWDM OADM supports two standard channel options, including 48 channels on 100 GHz ITU grid or 96 channels on 50 GHz ITU grid. No more than 48/96 DWDM channels, any wavelength or wavelengths combination can be customized upon request. But 50 GHz OADM is more expensive than 100 GHz, low channel numbers are not suggested.

Q: What else custom services can Arkoptics provide about DWDM OADM?

A: Any wavelength, any connector, any type of housing (/1U rack/ABS module/OADM components) and special ports like 1310nm/Monitor port( 1% ratio as default, 2%, 3%, 5%, etc, available on request) can be customized. What's more, Arkoptics OADM can be customized to industrial temperature -40~85℃ to meet the requirement of outdoor applications.

Q: I’m confused on the 1310 port, If you have multiple OADM's A--B--C where only A and C have 1310 ports. Would the 1310 signal pass through B, allowing A and C to communicate on the 1310 port?

A: Customized OADM can make 1310 signal pass through B, allowing A and C to communicate on the 1310 port. Arkoptics technical colleague will email you later.
