D25 Ethernet Card 100Base (10/100Base-T and 100Base-FX)
The D25 100Base card (GE part number 504-0305LF) is a dual-channel
10/100BaseT and 100Base-FX (1300 nm) network card that plugs into the
XCOM slot on the D25. It provides local area network connections for two
RJ-45 connectors and two ST connectors on the rear panel. The RJ-45 data
rate is automatically detected and set to either 10 Mbps or 100 Mbps.
Configuration
Options
There are no selectable options on the 10/100Base-T and 100Base-FX
Ethernet card.
Compatibility
The 504-0305LF card is compatible with both the 504-0205 and 504-0207
D25 Mainboards and all D25 Bases P114-0 v2.09 and up, regardless of which
D25 Ethernet XCOM card is selected in SGConfig.
The 580-0993 card is obsolete and is replaced by 504-0305LF. A 100BASE-
FX switch or converter is required when upgrading from 580-0993 to 504-
0305LF, since 10BASE-FL is incompatible with 100BASE-FX.
Fiber Optic
Cabling
You can use the following glass optical fiber (GOF) cabling with the D25
100Base FX:
•
50/125 μm core/cladding multi
-mode (gradient index) cable
•
62.5/125 μm core cladding multi
-mode (gradient index) cable
•
100/140 μm core/cladding multi
-mode (gradient index) cable
•
200 μm core Hard
-Clad Silica (HCS) multi-mode (step index) cable
You can use the following fiber optic terminations for D25 cabling:
•
ST Connectors
When calculating cable length, consider the following optical power levels:
•
100BaseFX optical transmitter power is –15.0 ± 4 dBm
•
100BaseFX optical fiber receiver sensitivity is typically –33.9 dBm
LED transmitters are classified as IEC 60825-1 Accessible Emission Limit
(AEL) Class 1M. Class 1M devices are considered eye safe to the unaided
eye. Do not view directly with optical instruments.
SQE test and
Jabber Support
Note
100BASE Ethernet does not have a provision to enable SQE test nor Jabber
as this is not part of the 100 Mbps standard. Refer to IEEE 802.3 clause
24.3.2.2 for further details on the removal of SQE test and Jabber in 100
Mbps Ethernet.
