Cisco ONS 15501 Erbium Doped Fiber Amplifier

The Cisco® ONS 15501 is a low-noise, gain-flattened C-band optical erbium doped fiber amplifier (EDFA) designed to extend the distance of today's high-speed optical infrastructure. The Cisco ONS 15501 complements the Cisco ONS 15500 dense wavelength-division multiplexing (DWDM) solution, providing customers with the capability to extend their 100-GHz, 32-channel, 2.5-Gbps, or 10-Gbps optical infrastructure over greater distances. Furthermore, the Cisco ONS 15501 integrates seamlessly with the Cisco Catalyst® 6500 Series, Cisco 7600 Series, and Cisco 12000 Series to provide inter-point-of-presence (POP) extension and the interconnection of remote campuses over 10 Gigabit Ethernet or SONET/SDH OC-192/STM-64. Packaged in a one-rack-unit (1RU) chassis, the Cisco ONS 15501 incorporates features such as 17-dB constant flat gain, automatic gain control (AGC), and low noise figure for excellent optical signal-to-noise ratio (OSNR) characteristics.

Enterprises using the Cisco ONS 15501 EDFA to extend their metropolitan-area (metro) DWDM network to remote data centers and branch offices can lower the total cost of ownership and deliver e-business solutions faster and more efficiently to all areas of their metro DWDM network.

With the Cisco ONS 15501 EDFA in a Cisco ONS 15500 network, service providers will realize greater revenue and profitability by extending the reach of their network infrastructure and services to remote customers.

Primary Product Features and Benefits

  • Constant flat gain of 17 dB over the 1530- to 1563-nm band
    • Constant gain and noise figure over the input power range of -29 to 0 dBm simplifies network design.
  • Metro optimized automatic gain control
    • Highly precise, rapid AGC capabilities allow the Cisco ONS 15501 to be used as a booster or inline amplifier.
  • Variable gain
    • The variable gain capabilities of the Cisco ONS 15501 are critical to network designs in which amplifier spacing must be flexible.
    • Variable gain allows for the addition or elimination of optical elements, such as optical add/drop multiplexing (OADM), without drastic network redesigns or costly equipment changes.
    • The adjustable gain of the Cisco ONS 15501 can be used to reset a network to a better operating point after a change in span loss.
  • Typical transient suppression within 50 microseconds
    • The overshoot and undershoot amplitudes are consistently <1.0 dB, even for the most drastic optical power level changes.
  • Low noise figure of < 6.0 dB
    • The low noise figure allows the use of up to six Cisco ONS 15501 amplifiers in cascade, while maintaining excellent OSNR for all channels.
  • Input power range of -29 to 0 dBm
    • The higher input power range available with the Cisco ONS 15501 can be used to increase the number of wavelengths in a system to 128 from the current 32 used, while avoiding spectral gain tilt effects.
  • Useful network management features
    • The Cisco ONS 15501 is fully manageable through Simple Network Management Protocol (SNMP), and has a console port to facilitate setup and monitoring of the unit.
    • Using the supplied MIB file, all parameters that can be monitored and set can be made available remotely.
