Optical interfaces (AM unit)
...................................................................................................................................................................................................................................
Overview
There are two aggregate STM-n (n=1, 4) interfaces (located on the main board) and
two
tributary STM-1 interfaces (located on the X2S11TRIB option card).
Optical connectors
The optical interfaces are equipped with SC connectors. If necessary, FC and ST
adaptors can be used which are supplied with the unit delivery. The next figure shows
the available optical connectors.
Specifications
The following types of interfaces are available:
• Aggregate interfaces:
– STM-1 short haul (S1.1) + 18dB variant
– STM-1 long haul (L1.2)
– STM-4 short haul (S4.1)
– STM-4 long haul (L4.2)
• Tributary interfaces:
– STM-1 short haul (S1.1).
The characteristics of the optical interfaces are summarized in the table below.
