Light Brigade delivers fiber optics knowledge and skills training globally. Based out of Kent, WA, our network of veteran instructors are able to train students to reach a number of industry-recognized certification standards. Our original founder, Larry Johnson started his crusade to broaden the industry's fiber optic knowledge, forming the corporation in 1990. Since then, we have trained over 60,000 students, equipping them with the skills required to move forward in their careers.
Delivering both standard and customer-specific classes we can ensure the training matches the student's need, both in theory knowledge and practical skill sets. We partner with leading industry bodies to provide certification, including Fiber Broadband Association (FBA), Electronic Technicians Association (ETA), Utilities Telecom Council (UTC), and continuing education credits thru BICSI.
Are you using a YB laser for communications? What else is in your link? Assuring you have APC connectors and keep all interfaces very clean and precise will be helpful.
There is no cookie cutter 1 size fits all spec for Optical Return loss. The length of the fiber under test determines that. A short link less than 1 mile with "no significant reflections" should have an ORL reading in the low +40's and a long link like 30 miles will be fixed around +32. If you are testing a 1 mile span and have an ORL of +33, you have a serious issue in that link. 1 X32 splitters do NOT need optical terminators. The nearly 17db loss thru the 1 X 32 splitter will attenuate down any reflected light. This has been proven on a test bench and in the field. Putting optical terminators on a 1 X 32 splitters is a total waste of time that will do nothing.
Thank you for your comment. As with many technical topics, there are often many scenarios and often more than one good answer. We encourage our students to provide us with as much detail as possible about their applications, products used and specs in order to give the best answers possible. In the previous response about terminators, we did not mean to imply this was always the answer. Also, generalizing ORL against link length is hard as well, unless we know exactly what is in that link.
I am adding a comment here as proof that I did track down this webinar after a 404 error on ISE Mags site and watched this webinar for BICSI CEC credit
Thanks for your note! You can find the Online CFHP course info and register to take the course here: learn.lightbrigade.com/lms/courses/5-certified-fiber-to-the-home-professional/preview
Fiber to the home networks are built with single-mode fiber, so OM5 multimode fiber would not likely come into play for this scenario. By using SM fiber, the distance from the CO to the homes can be quite long, but it is dependent on the other components in the network and how much loss they contribute (like splitters, connectors, splices, etc.).
No worries. We have many newer webinars available, but OTDRs continue to be used in the field every day. Our courses cover current technologies as they become relevant for our students.
Hello I have a FTB-100B miniotdr,and i have a problem with him. When i press the button to start,on the screen appear initial settings,but i can't do anything..when i press the touchscreen i hear the pressing but nothing happens. Do you know what could have. Thanks
The general protocol would be to cycle the power completely. Turn power button off. Wait 30 secs for the unit to completely power down. Remove the battery from the unit. Wait an additional 30 seconds. Replace battery in unit. Power on. If this does not fix the problem then we encourage you to call EXFO directly.
APC connectors are always helpful. If the fiber is connectorized, a 'terminator' at the end will help. What specific problem are you having where the end reflection is a concern? We would prefer to recommend a solution to a more specific problem :)
This depends on how much of the reflection is required to be either eliminated or minimized. This will also depend on the type of fiber being tested. For most systems an optical terminator is sufficient. Check the specifications though for the value needed. Is the fiber terminated or the end of a fiber? You can also dip the end of the fiber in index matching gel. There are several other techniques which we can assist you with based on the questions about the fibers, terminations etc.
Now I understand that Sweden must use APC if we want to meet the future standard. 10Gb/ 40Gb/ 100Gb/ New standard 25Gb/ 50Gb/ 200Gb. The future 100Gb standard to : 400Gb/ 1.6Tb/ 6.4Tb and the future speeds. . . .
I think that Sweden don´t use B-PON anf G-PON systems today. But I work regarding DataCenter products today. This is most for SM G.652D (SC/UPC connector) and OM3 - OM4 fiber. And I look to the future for OM5 fiber. What is SDH (SONET)? Do you have any info regarding Sweden fiber to the future? Sweden normaly use a lot of UPC to FTTH market. Do you think that Sweden have to use APC conetors to all FTTH customers! (SM fiber with LC/APC for the future!) And what do you think regarding DataCenter´s MM with LC/APC for OM5 fiber? And what will the we use to MTP/MPO for MM fiber in the future? MPO-16 ore MPO-12 with APC polich for MM fiber? What is the future?
OTDR & a fiber microscope is a daly use today. And with EN-61300-3-35 if you want the right info from the microscope, OTDR = Tier 1 and all need this in the future.
