1345-Type Receiver with
Clock Recovery and Data Retiming
Data Sheet
January 2000
Installation Considerations
Although the receiver has been designed with ruggedness in mind, care should be used during handling. The opti-
cal connector should be kept free from dust, and the process cap should be kept in place as a dust cover when the
device is not connected to a cable. If contamination is present on the optical connector, the use of canned air with
an extension tube should remove any debris. Other cleaning procedures are identified in the Cleaning Fiber-Optic
Assemblies Technical Note (TN95-010LWP).
Characteristics
Minimum and maximum values specified over operating case temperature range and end-of-life (EOL). Typical val-
ues are measured at beginning-of-life (BOL) room temperature unless otherwise noted.
