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

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.

Table 1. Electrical Characteristics

1. Customers have the option for either a +5 V or –5 V supply.

2. Includes approximately 50 mA of DATA and CLOCK output termination current.

3. Measured with 50

4. DATA and CLOCK outputs are 10K ECL compatible.

5. Measured as shown in Figure 4.
