The SIF module is able to support up to four independent 15 MHz Digital IF (DIF) data
streams (15 MHz band blocks) consisting of either four (4) forward path signals and four (4)
reverse path signals in a non-diversity configuration, or two (2) forward path signals and four
(4) reverse path signals in a receive-diversity configuration. The references for the SIF are
shown in Table 2-9.

DESIGNATION
DEVICE FUNCTIONAL DESCRIPTION
1 DIF Input 1-4 LED Multi-colored LED
(Green/Yellow/Red)
Indicator showing if the interface is not
enabled (off), good (green), degraded
(yellow), clock issue (blinking), or no DIF
tone lock or unused channel (red).
2 DIF Output 1-4 LED Multi-colored LED
(Green/Yellow/Red)
Indicator showing if the interface is not
enabled (off), good (green), degraded
(yellow), clock issue (blinking), or bad data
on output of unused channel (red).
3 Ethernet Connector RJ-45 connector Provides IP connectivity over fiber
4 Hot Swap LED Single-colored LED
(Blue)
Status indicator turns blue when board can
be hot swap extracted.
5 Power LED Single-colored LED
(Green)
Status indicator turns green when module
has power.
6 Fault LED Single-colored LED
(Red)
Status indicator turns red when module has
failed. Indicator is lit during start-up until
the module has initialized.
7 SFP Fiber Optic
Connector
Dual-LC connectors Fiber connector on SFP optical transceiver.
8 Optical Output LED Multi-colored LED
(Green/Yellow/Red)
Indicator showing if the SFP interface is
not enabled (off), good (green), degraded
(yellow) or bad output signals (red).
9 Optical Input LED Multi-colored LED
(Green/Yellow/Red)
Indicator showing if the SFP interface is
not enabled (off), good (green), degraded
(yellow) or bad framing, bad parity, no
signal, or no signal lock (red).
5.4 Small Form-Factor Optical Transceiver (SFP)
The small form-factor pluggable optical transceiver (SFP), shown in Figure 2-15, provides the
optical interface between the Hub equipment and the RAN hardware. The Digivance CXD
system uses industry standard SFP optics which offers a number of configuration options
depending on the requirements of the project. The SFP modules are typically factory installed
with the SIF, or may be purchased separately depending on the system as ordered.
