Keysight 81000BR Reference Reflector

 Data Sheet

This instruction Sheet provides information for using a Keysight Technologies, Inc. 81000BR Reference Reflector. This is a gold-plated HMS10 connector for use when measuring the return loss of optical connectors. It allows you to take a highly precise reference at the device under test. It can also be used with the 8156xA , 8157xA Optical Attenuator Modules or 8156A Optical Attenuator to create a variable back reflector.

 Return Loss

The return loss is 0.18dB±0.1dB (96%±2%). This value is specified for the 1310nm and 1550nm wavelength windows, using single mode fiber. These values are typical at other wavelengths, and for other types of fiber.

Note

The 81000BR Reference Reflector is sub­ject to wear. It has a useful life of at least 100 connections when carefully used.

Caution

The performance of the 81000BR Refer­ence Reflector deteriorates easily by rough handling. To maximize its useful life, handle it gently and in particular:

• Ensure that both the surface of the reflector, and the connector to which you connect it, are free of particles of dust and dirt (See “Cleaning Instruc­tions”).
• Make sure that the reflector is cov­ered by a protective cap when it is not in use.

Cleaning Instructions

Use this procedure when there is greasy dirt on the adapter:

1. Using the blow brush, or dry clean compressed air, remove dust.

2. Wipe the surfaces with the special cleaning tips.

3. Apply some isopropyl alcohol to lens cleaning paper, and clean the surface and the ferrule of the connector.

4. Using a new, dry piece of cleaning paper, wipe the connector surface and ferrule until they are dry and clean.

5. Lightly press the adhesive tape several times against the connector surface to remove any remaining particles. After use store tape in its container.

6. Protect the connector surface by attaching the connector adapters or a cap.
