For the increasing powers of DWDM systems, the laser Maximum Permissible Exposure Ansj levels in Part 1 of the IEC a136.2 must not be exceeded if any person can be exposed to laser radiation emerging from the port or fracture from the instant of disconnection or break until the power reaches an acceptable level.
If automatic power reduction APR is used, the normal level of power in the fiber and the speed of the APR system determine the hazard level. The high bandwidth and low noise of optical systems led to their rapid adoption in undersea as well as landline communications networks.
This standard is also available in these packages:. However, it also recognizes that, during service operations, optical connectors are removed and there is a risk of exposure to optical energy if the system is energized.
Ehrgott The communications industry was revolutionized in the s with the advent of optical fiber communications systems OFCS consisting of diode lasers emitting infrared light signals at wavelengths chosen for transmission with minimal loss in high purity glass fibers. In the s, optical amplifiers called erbium-doped fiber amplifiers EDFA began replacing electro-optical systems for long-distance OFCS signal regeneration and amplification.
Need more than one copy? However, IEC also recognizes that such a classification may not reflect accurately all potential hazards. We have no amendments or corrections for this standard. To address such situations, this standard recommends that an appropriate “service group” be assigned based on the potential radiant energy hazard and specifies appropriate controls for each service group. Engineering and administrative controls are specified by IEC for the hazard level and type of environments in which the OFCS may operate.
This standard is also available to be included in Standards Subscriptions. IEC recognizes that an OFCS is technically a Class 1 z316.2 system because, under intended operation, the optical radiation is totally enclosed. The service group ansl classification scheme considers the special viewing conditions when cables are severed or disconnected.
Over the past several years, the laser safety standards community has been working on updating the standards so as to address this emerging technology. This standard addresses hazards and provides guidance for the safe use, maintenance, service, and installation manufacturer of optical communications systems OCS utilizing laser diodes or light emitting diodes LED operating at wavelengths between 0.

Available for Subscriptions Available in Packages Standard is included in: It recognizes that, under normal operation, an OFCS is completely enclosed and that no optical energy is accessible to the operator or incidental personnel inherently Class 1.
If the document is revised or amended, you will be notified by email. Hazard Level 4, analogous to a Class 4 laser, is not permitted in any location. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.

This means that any OFCS carrying Class 4 optical power levels needs to incorporate control mechanisms to reduce the power to an acceptable hazard level in the case of a reasonably foreseeable event that would permit access to the radiant energy from a fiber or cable. She received a B. EDFAs are further advancing OFCS technology by enabling simultaneous transmission of multiple signals of different wavelength in each optical fiber.
This technology is gaining popularity in the communications industry based on various advantages, including the fact that this portion of the spectrum is not regulated by the FCC, and frequency coordination is not required does not produce radiofrequency interference.
