Customized to customer’s specifications

DHD makes customized optics for ranges that OEM does not make. This allows for our end users to get creative and lowers costs.

Global Delivery

With over a million dollars of inventory available, we can provide a wide range of optics with a quick turnaround.

Every Order

Every order is a custom-selected, coded and platform-tested to ensure that our optics are 100% compatible and reach the distance they are intended to hit with minimal interference. When requirements are unclear, our team of experts works with you to define the right solution.



Our extensive 7-step internal testing process gives...and will work from the get-go. Different manufacturers can produce widely differentiating results. We test extensively to ensure you receive products that are consistent in overall quality.


Steps to Insure the Highest Standards

Our process starts with best-in-class manufacturers of MSA spec transceivers. These companies follow rigorous design verifications and test processes that meet performance standards set by OEM’s. Through years of testing a wide variety of parts from many manufacturers, DHD has developed a refined approved vendor list of companies that consistently deliver high quality parts. These companies routinely conduct comprehensive functional and environmental testing to industry standards and hold ISO, RoHS and other key certifications. The second step is to select and approve parts to add to DHD’s approved parts list. This selection criteria includes reviewing performance specifications against our knowledge base of compatibility requirements as years of experience have identified issues not always captured in communication industry standards. Sample parts are acquired and then tested to meet key specifications for bit error rate, transmitter accuracy and receiver sensitivity.

Parametric Testing

The following parametric tests are done over a range of environmental conditions depending on commercial or industrial usage. Using Digital Diagnostic Monitoring (DDM), we verify thresholds to industry standards.

• Output Power
• Receive Power
• Module Voltage
• Laser Bias Current
• Optical Fiber Scope Inspection
• Receiver Sensitivity
• Sensitivity
• Temperature
• Wavelength Verification for WDM Products
• Extinction Ratio
• Dispersion Tolerance Testing
• Eye Diagrams


Disassembled Inspection

Next, parts are disassembled to inspect assembly workmanship, cleanliness of optical and electrical connectors, component quality and design fit.


The last step in the parts qualification process is coding and application testing in a wide variety of platforms. Depending on the form-factor, a part will be tested in as many as 50 different platforms or combinations of chassis, controllers, line cards and operating system revisions from multiple OEM’s. Test results are recorded for each configuration and added to DHD’s part compatibility matrix.

Application Testing

In collaboration with our customers, we have developed unique configurations that create or emulate known system incompatibilities. A qualification checklist with up to 15 quality checks is used to summarize all our testing and verify the adherence to industry part (PMD) standards.

Traffic functionality TX/RX per supported layer 2/3 protocol.

• Brand specific EPROM values are verified.
• EEPROM MSA Value Verification.

Head to Head Comparison of DHD Optics

Value = Quality - Cost
We believe that something is of great value only when the price is good, the quality of the product is strong AND it meets a need.

“Value” Conclusion and Recommendation
Cheaper isn't a savings when you lose value. And something that is junk can be overpriced. Customer downtime isn't worth the risk of saving a few dollars up front on cheap fiber optics. Our end users are much better off spending a little more for a good product versus saving money on an unknown product with a short lifespan.
