How FS Transceiver Tests Make Your Connection Effortless
Updated at Jan 9th 20231 min read
As important equipment for network transmission, optical transceiver has great influence on network performance like signal transmission distance and reliability. Quality claims are easy to make, but very few vendors can keep the promise. However, FS makes it. FS transceivers have been highly praised by our customers and influencers in the industry.
"So these are all the server end transceivers that we're gonna be using. These are 25 gigabit from FS.com. Massive shout-out to those guys. Great compatibility, great performance, and did I mention the price? Freaking awesome."

How FS Transceiver Key Tests Make Your Connection Effortless
FS Transceiver 100% Full Test Process
FS has always attached great importance to the quality of its products, and in order to make your network connection easier, the company has invested in a test center (approximately 30,000 square meters) with a variety of world-class test equipment. Among them, FS Optical Transceivers Testing Lab ensures the high quality and reliability of FS optical modules through a series of comprehensive tests.
Power and Wavelength Testing verify signal strength and wavelength consistency for accurate signal decoding. Traffic Testing checks bit error and packet loss rates to meet performance standards. Optical Performance Testing assesses factors like eye diagrams, sensitivity, and extinction ratios, ensuring signal stability and transmission quality. End Face Testing ensures clean surfaces for stable data transmission and durability. Additionally, Compatibility Testing with over 200 targeted switches, including Cisco, Juniper, Brocade, and Arista, guarantees seamless interoperability. These rigorous tests demonstrate FS’s commitment to product reliability and performance. What's more, we have designed a rigorous testing process. Every transceiver module must pass all the tests before reaching you. Though it may take more time and costs, fairly stable performance is the priority of FS. You can find the test steps of FS transceiver in the following figure.

FAQs About FS Transceiver Key Tests
Q1: What test does FS do to keep low power consumption for data center?
A: It's said that in 2030, data center electricity will take up 3~13% of the global amount, since global data center construction is developing so rapidly with continuous growing bandwidth. Transceivers, as one of the critical data transmission equipment in data centers, due to the large quantity, can cause lots of power consumption, especially those high data rate transceivers. So, it's necessary to keep low power consumption for data center transceivers.
To provide you more stable and energy saving data center transceivers, FS has constructed automated optical performance parameter tests such as eye diagrams, current, and voltage.

Q2: What test does FS do to meet 5G network application requirements?
A: For 5G fronthaul transceiver, it's required that the operation temperature must support from -40 to 85°C (-40 to 185°F) as it's applied in the outside harsh environment. At the same time, it must possess features like low latency and high speed.
Thus FS applies temperature tests to guarantee our 5G industrial transceivers performance between -40 to 85°C (-40 to 185°F) and traffic tests for low latency with a high data rate.
Q3: How does FS test ensure long distance transmission for WDM network?
A: WDM transceivers are designed for high capacity and long distance transmission. When you buy a WDM transceiver which can support 80km transmission distance, you may find it can't support the distance as it's said once you build the connection. As it may be influenced by dispersion and nonlinear effects.
To make sure our WDM transceivers can support long enough transmission distance, FS can detect the side mode suppression ratio (SMSR) and extinction ratio for high receiving sensitivity and low transmission loss via Anritsu MS9740A spectrum analyzer.

Q4: How does FS test for interoperability?
A: There are always different brands of equipment in a network system, which may cause incompatibility issues as not every supplier can ensure its optics 100% compatible. To guarantee interoperability, each FS transceiver module must be individually tested for compatibility in our world-class test lab with the latest networking equipment (over 200 network systems).
