Dynamic fiber layer management for test lab automation

Communications providers and data center operators rely on system test labs to rigorously test new equipment and to verify network service quality, reliability, and security, before deploying in their infrastructure. These test labs are also used to simulate customer network environments so that issues can be identified and resolved quickly without deploying technicians in the field.

As networks rapidly move to higher 100+ Gbps speeds and beyond, and more connected devices and equipment are required to deliver expected services, the network test lab is becoming increasingly complex and expensive. Traditional optical-electrical Layer 2/3 devices typically used to interconnect equipment in test beds simply can no longer handle the number of connections and higher speeds needed to test configurations with a high degree of accuracy. And, having to physically switch out network interface modules, or in some cases, perform complete forklift upgrades when a different frame format or data rate is implemented, leads to slow test and verification cycles and can introduce more potential for errors.

The introduction of all-optical switching to the network test lab environment brings tremendous flexibility and cost-savings that enables operators to automate their test operations. Benefits include:
  • Reduced OPEX. With the ability to connect any port to any port, equipment can be cabled once and tests can be configured instantly, saving roughly 75% of cabling time. Remote testing can be conducted from anywhere in the world, so staffing and travel expenses are greatly reduced.
  • Reduced CAPEX. Expensive test and network equipment can be shared across multiple tests and multiple system test lab environments, decreasing repetitive equipment purchases and saving on power and scarce real estate resources.
  • Improved Accuracy. All-optical connections are completely transparent, with no packet processing, so tests are conducted with a high degree of accuracy.
  • Greater Test Coverage. Using integrated variable attenuation and shutter features, optical switches can stress-test system responses to physical layer faults such as connector degradation and difficult-to- trace intermittent fiber micro-breaks.
  • Faster Customer Response.. Customer network configurations can be recreated and simulated quickly so that potential corner case issues can be identified and resolved faster.
  • Competitive Advantage. The longer it takes to certify gear, the bigger the challenge for operators to roll out new services ahead of competitors. Fiber layer automation speeds up certification and facilitates deployment of more robust solutions.
  • Future Proof. All-optical switches are transparent to transmission wavelength, direction, protocol and bit rate so the same optically-switched lab infrastructure can be used for any media and speed up to 400Gbps and beyond.
