A.14.1 Functional Details
Fiber
The 10G-SS fiber to fiber 3R repeater uses a transparent optical line coding and clock data recovery to provide
an optical repeater / transponder function for use in extension or CWDM applications at speeds up to 10G.
Only SFP+ model is available. (See 10G-SXX model for XFP support.)
Management
The FRM220-107G-SS has a small processor that is used to read the set DIP switches when used stand-alone
or to communicate with the NMC when placed in the managed rack. This model is designed for both stand-alone
use and for management when installed in managed chassis.
When placed in a managed chassis, such as our FRM220-CH20 with NMC (Network Management Controller),
the 10G-SS card is configured and monitored through the chassis NMC via console, Telnet, Web HTTP or SNMP.
1. Stand-alone – DIP settings when placed in CH01, serial console when placed in CH01M or CH02M.
2. Rack management - When placed in NMC managed rack, all other settings can be overridden by the NMC management.
3. 10G-SS does NOT support in-band management.
A.14.2 Installation of SFP Modules
CTC Union supplied SFP and SFP+ modules are of the Bale Clasp type. The bale clasp pluggable module has
a bale clasp that secures the module into the SFP cage.
A.14.2.1 Inserting a Bale Clasp SFP Module into the Cage
Step 1 Close the bale clasp upward before inserting the pluggable module.
Step 2 Line up the SFP module with the port, and slide it into the cage.
A.14.2.2 Removing a Bale Clasp SFP Module
Step 1 Open the bale clasp on the SFP module. Press the clasp downward with your index finger.
Step 2 Grasp the SFP module between your thumb and index finger and carefully remove it from the SFP cage.
