Section 4

Modules

This section identifies and provides detailed information on all modules that you can use with

the SG4000. It also discusses their installation, removal, and cleaning of the optical connectors

where appropriate. All of the SG4000 optical modules are equipped with SC/APC connectors but

may be ordered with SC to E2000 adaptors.

The forward path optical modules include:

 SG4-R forward path optical receiver

The return path optical transmitter modules include:

 SG4-IFPT — isolated Fabry-Perot, 0.4 mW, 1310 nm

 SG4-EIFPT — enhanced, isolated Fabry-Perot, 1.0 mW, 1310 nm

 SG4-DFBT and SG4-DFBT3 — isolated Distributed Feedback, 1.0 and 2.0 mW respectively,

1310 nm

 SG4-DFBT3-*-CWDM — isolated Distributed Feedback, 2.0 mW, eight 1550 nm

wavelengths

 SG4-DRT-2X — 6.3 mW, DWDM ITU channel, 2X TDM digital return

Installing SG4000 Optical Modules

The SG4000 optical modules design enables you to install them while the node is in service. The

module’s flat bottom provides an excellent thermal transfer surface and has locating holes that

align with guide pins in the lid of the node.

To install an optical module:

1 Determine the proper slot for the module by referring to Section 3, “Bench Setup and

Operation,” and Figure 3-2.

2 Position the module in the appropriate slot and press gently on the casting until it is fully

seated.

3 Tighten the three 1/4 inch mounting bolts to 8–12 in-lbs to secure the module in the SG4000

lid.

4 Remove the dust covers from the service cable connector and the module’s optical connector.

5 Carefully clean the optical connector using a suitable optical cleaning kit.

6 If necessary, check the optical power levels.

7 Connect the service cable to the module’s optical connector.

8 Attach the appropriate RF cabling to the optics module.

9 Check and align the RF levels in accordance with system requirements and procedures.
