Note:
z
The cable marked TX on it should be connected to the cable marked RX of the peer
device and the RX cable should be connected to the TX cable of the peer device.
z
The device does not support the 8E1(120)/8E1(120)-F interface module. If the peer
device uses an 8E1(120)/8E1(120)-F interface module, you need to equip a
75-to-120 ohm converter.
z
The coaxial connector, 75-ohm E1 trunk cable, and 75-to-120 ohm converter are
optional accessories to be separately purchased if needed.
XI. Connecting a POS interface module cable
The POS interface module is sold together with the following three types of SFP
modules:
z
Multimode SFP module–2 km (1.2 miles)
z
Single-mode SFP module–15 km (9.3 miles)
z
Single-mode SFP module–40 km (24.9 miles)
You need to install an SFP module before connecting optical fiber cables.
The POS interface module uses optical fiber cables with LC connectors. For details,
refer to section 2.1.3. V “Interface cable” in Chapter 2 “Interface Modules”.
1) Install an FIP-100/FIP-200 in an LPU slot on the router. For the installation
procedure, refer to section 8.5.2 “Installing FIP-100/FIP-200” in Chapter 8
“Maintaining Hardware”. Skip this step if an FIP-100/FIP-200 is already installed.
2) Install a POS interface module in a sub-slot on the FIP-100/FIP-200. For the
installation, refer to section 8.10 “Installing and Removing an MIM” in Chapter 8
“Maintaining Hardware”.
3) Insert an SFP module in the SFP interface of the POS interface module.
4) Identify the Rx and Tx ports on the SFP module. Plug the LC connector at one end
of one fiber cable into the Rx port of the router and the LC connector at the other
end into the Tx port of the peer device. Plug the LC connector at one end of
another fiber cable into the Tx port of the router and the LC connector at the other
end to the Rx port of the peer device.
5) Check the status of the LINK LED on the interface module panel after connecting
the cables.
z
If the LED is on, a link is present.
z
If the LED is off, no link is present. In this case, the Rx and Tx ports may be
connected incorrectly, and you can try to change the positions of the LC
connectors of the two optical fiber cables at one end to remove the fault.
