Telcordia Reliability Testing with Environmental Chambers

 

Telecommunications, fiber optic, photonic, and network infrastructure products are often required to comply with Telcordia® Generic Requirements (GR) to demonstrate product reliability, durability, and long-term field performance. Originally developed by Bellcore and now maintained as Telcordia standards, these specifications are widely recognized throughout the telecommunications and optical communications industries for qualifying products exposed to demanding environmental conditions.

Many Telcordia standards require environmental testing to evaluate how products perform when subjected to temperature extremes, humidity, thermal shock, altitude, and other environmental stresses encountered during operation, transportation, and storage. These tests are frequently used alongside related IEC, MIL-STD, TIA, and EIA test methods to verify product reliability and service life. CSZ environmental test chambers are designed to help manufacturers perform Telcordia reliability testing with precise control of temperature, humidity, and other critical environmental conditions. Our chambers support qualification testing for a wide range of telecommunications and networking products, including:

 

  • Fiber optic connectors and jumper assemblies
  • Optical transceivers and optoelectronic devices
  • Passive optical components
  • Fiber optic branching components 
  • Telecommunications line protection devices
  • Network switching systems
  • Outdoor network interface devices
  • Electronic equipment cabinets and enclosures
  • Telecommunications infrastructure equipment
  • Data communication and networking hardware

Whether you are developing products for telecommunications networks, fiber optic communications, broadband infrastructure, or optical networking applications, CSZ provides environmental test chambers capable of supporting Telcordia qualification and reliability testing requirements.

The Telcordia specifications listed below are among the most commonly referenced standards requiring environmental testing. For each specification, we outline the applicable test conditions and recommend suitable CSZ chamber solutions for performing the required qualification testing.

Telcordia (Bellcore) Generic Requirement Description/Applicable Product
GR-49-CORE for Outdoor Telephone Network Interface Devices
GR-63-CORE for Network Equipment-Building System Requirements (NEBS): Physical Protection
GR-326-CORE for Single Mode Optical Connectors and Jumper Assemblies (Fiber Optics)
GR-468-CORE for Optoelectronic Devices Used in Telecommunications Equipment
GR-487-CORE for Electronic Equipment Cabinets (Enclosures)
GR-974-CORE for Telecommunications Line Protector Units (TLPUS)
GR-1209-CORE for Fiber Optic Branching Components
GR-1221-CORE for Passive Optical Components

The above list is not intended to be inclusive of all Telcordia Generic Requirements that require environmental testing. If you have a test requirement for other Telcordia specifications, contact us to see how we can meet your needs.

We also provide ports of various sizes (circular, square and rectangular) for your cable routing needs. You simply specify your port location and fixture needs. Every Telcordia (Bellcore) specification referenced above requires testing at the low temperature of -40°C. Our Tundra system can efficiently test your product down to the low temperature of -45°C and be included in any environmental chamber.

What environmental tests are commonly required by Telcordia standards?

Depending on the specification, testing may include temperature cycling, high and low temperature exposure, humidity testing, thermal shock, altitude simulation, accelerated aging, vibration, and mechanical shock.


What is the difference between Bellcore and Telcordia standards?

Bellcore originally developed many telecommunications reliability standards. These standards are now maintained under the Telcordia name and continue to be widely used throughout the telecommunications and fiber optic industries.
