• SONET OC-3LR-1 optical interface

– Rate: 155.52 Mb/s

– Span length: Long Reach, 40 km

– Wavelength: 1310nm (nominal)

NOTE

The OPTI-3 is an LR (long reach) optical product.

When interfacing with IR (intermediate reach)

3rd party equipment, the optical receive signal

may need to be padded to avoid overloading the

optical receive signal. The receive signal level

should be within −8 dbm to −28 dbm for IR

equipment.
