iSPY - Hardware
• Chassis
• Controller
• Laser
• Optical Power Monitor
• 1xN Switch
• 1x2, 1x4 Switch
• OTDR
15
Chassis
• Hot Swappable Modules plug into back-plane
• -48 VDC / 100-240 VAC
• Communications via RS-232 or Ethernet
• Daisy chain multiple chassis (RS-485)
• 3U, 4U, 5U, 8U sizes
16
Controller
• Provides communication between user and modules
• Controls operations of all modules through chassis back-plane
• Communications via RS-232 or Ethernet
• Control through TL1, or GUI
17
iVAM 1550 nm Laser Source
• 1550 nm stable laser source
• Single mode
• -15 dBm power output after 1x16 splitter
• Reaches over 180 Km
18
1xN OTAU
• OTAU is a Telcordia term for Optical Test Access Unit
• 1 x N or Dual 1 x N switch (1x4 to 1x130)
• Plugs into back-plane, controlled by controller module
• Switch between test fibers and test equipment
• Leverage OTDR over many circuits
19
Remote OTDR
• Remote operation
• Plugs into back-plane
• One slot space
• 1310, 1550, 1625 nm
• 35-41.5 dB dynamic range
20
Optical Power Monitor (OPM)
• 4 and 8 channels
• Monitors power levels
• Able to set thresholds
• Alarms
• Range: +3 to -50 dBm (other ranges available)
• +/- 0.02 dB resolution
• +/- 0.2 dB accuracy
• 850, 1310, or 1550 nm Multimode and Singlemode
• NEBs qualified
22
Monitoring
• Real-time monitoring
– Optical power measurements every 250 msec.
• Set minor and major alarm thresholds
• Stores minimum and maximum power levels
• View current power level on any fiber
• Monitoring by dedicated power monitor modules
– Maximizes OTDR life
– OTDR used for fault location
• Stores alarm history
31
iSPY System Software
• Multiple user administration levels
– Each user has unique login and password
– Administrator – full rights for user and system setup
– User - read-only, receive alarms, launch traces
• Alarm history log
– Stores all link status alarms and failures
– Stores both time of alarm and return to normal
• Auto calibration
– The server performs a regular system calibration
– Calibrates laser changes over time, temperature variations on fiber, etc.
• Communication assurance
– System sends a Heart Beat signal from server to all modules
• Power failure alarm
– Power failure alarm via dry-relay contacts
32
iSPY System Software
• Client-Server Architecture
• Client and Server software run on Windows, Linux,
Sun, Mac (anything that supports Java 1.5)
• Software can run on an existing server/computers
• Server uses 112 MB and client uses 105 MB
• Unlimited number of users
• HSQLDB database
• Hibernate ORM mapping allows mapping to other
databases
