Installation
Connecting to the Network
1. Use of controls or adjustments or performance of procedures other than
those specified herein may result in hazardous radiation exposure.
2. Always fit the fibre optic connector dust caps on each connector when
not in use. Before connection is made, always clean the connector ferrule
tip with acetone or alcohol and a cotton swab. Dry the connector with
compressed air. Failure to maintain cleanliness of connectors is liable to
cause excessive insertion loss.

CLASS 1 LASER PRODUCT
CLASS 1 LASER PRODUCT translates as follows:
Finnish - LUOKAN 1 LASERLAITE
Finnish/Swedish - KLASS 1 LASER APPARAT
This label indicates that the radiant energy present in this instrument is
non-hazardous.
Allows connection of an optical signal, wavelength 1200 to 1600 nm, at a
maximum power level of -8 dBm. NEVER EXCEED +3 dBm.
Accepts STM-0, STM-1, STM-4 and STM-16. Also accepts SONET
signals, STS-1, STS-3, STS-12, STS-48, OC-1, OC-3, OC-12 and OC-48.
Provides an STM-0, STM-1, STM-4 or STM-16 optical signal (OC-1, OC-
3, OC-12 or OC-48 SONET signals) at wavelength1280 to 1330nm, and/
or 1550 to 1565 nm, at a nominal power level of +1 dBm.
