2-12 Interfaces and Connections
Fiber Optic Link Connections
Eye damage may be caused by a broken or non-terminated fiber-optic or
connector if the laser beam is viewed directly or with improper optical
instruments.
One or two (main and backup) link interfaces are provided according to order.
The fiber optic interfaces can be of optical type only.
In normal operation a module must be installed in the main link.
For the properties and specifications of the optical link interfaces, refer to the Fiber
Optic Interface Options table.
When working with WDM modules, the two types SF1 and SF2 must work one
opposite the other. SF1 does not work opposite SF1 and SF2 does not work
opposite SF2.
While link redundancy is OFF, it is recommended not to install the backup link so
as not to receive a major alarm indication (while the backup link is in sync loss).
Connect each fiber optic link interface (main and backup), in accordance with the
type of interface installed for that link as indicated in Table 2-6.
Table 2-6. Fiber Optic Link Connections
Interface Connector Type Note
Optical ST, SC or FC/PC Avoid sharp bends of the optical cables. The minimum bending
radius should be 30 mm (1.2 in).
Cleanliness of the optical connectors: use an approved solvent, and
dry thoroughly using optical tissue.
Connection of the receive cable to the optical connector designated
RX and the transmit cable to the optical connector designated TX.
Alarm Connection
The alarm cable is terminated with a 9-pin D-type male connector on the unit
side. The maximum rating of the alarm relay contacts for planning the monitoring
means and cabling is 1 Amp, 60 VDC and 30 VAC.
The dry contacts of the Optimux-XLT1 alarm relays (major and minor) are
connected to a remote monitoring site via the rear panel ALARM connector (see
Figure 2-7).
