OC-N / STM-N Overview
The OC-N / STM-N is an 8-port optical LIM intended for use only with a PCX
slot controller for high speed ATM connections and Packet over SDH/SONET.
It supports a maximum cell rate of 1,412,830 cells/sec and a physical line rate
of 622 Mbps.
Front Panel Features
The front panel connectors provide easy port access to the eight ports. Each port
requires a Singlemode or Multimode SFPs (Small Format Plugable) insert to be
operable. Available SFPs are listed below:
•
Singlemode: OC-N/STM-N SR (2K) 1310nm
•
Singlemode: OC-N/STM-N IR (15K) 1310nm
•
Singlemode: OC-N/STM-N LR (40K) 1310nm
•
Singlemode: OC-N/STM-N LR (80K) 1550nm
•
Multimode: OC3/STM1-SR (2k) 1310 nm
The front panel LEDs indicate LIM communication status. All LEDs are
controlled by the PCx software. There are two LED indicators associated with
each port.
•
When lit, IS indicates that the port is enabled.
•
When lit, AL indicates an alarm condition.
Hardware Setup
Cabling
Optical connector cables compatible with the installed SFPs are user-supplied.
Jumpers
Jumpers on the OC-N/STM-N LIM are for factory use only.
Installation
The OC-n / STM-N LIM occupies a rear panel slot of the switch that is
associated with the corresponding PCX scontroller. When handling LIMs,
always use an antistatic wrist strap to prevent static discharge damage to the
electronic circuits.
1. Install the LIM into an empty PCx slot at the back panel of the chassis.
2. Insert the edges of the module into the tracks of the slot and slide the
module inward until it stops. (LIMs are "hot-swappable".)
3. Refer to
OC-N/STM-N Applications on page 5-5
application.
4. Connect the appropriate I/O line(s) to the LIM's front panel input
connectors using the proper cables.
5. Refer to the Xedge Configuration Guide to properly configure the LIM for
your application.
