Note	For OPT-RAMP-C or OPT-RAMP-CE card safety labels, see "Class 1M Laser Product Cards".

The OPT-RAMP-C card is a double-slot card that improves unregenerated sections in long spans using the span fiber to amplify the optical signal. Different wavelengths in C-band receive different gain values. To achieve Raman amplification, two Raman signals (that do not carry any payload or overhead) are required to be transmitted on the optical fiber because the gain generated by one signal is not flat. The energy of these Raman signals transfer to the higher region of the spectrum thereby amplifying the signals transmitted at higher wavelengths. The Raman effect reduces span loss but does not compensate it completely.

When the Raman optical powers are set correctly, a gain profile with limited ripple is achieved. The wavelengths of the Raman signals are not in the C-band of the spectrum (used by MSTP for payload signals). The two Raman wavelengths are fixed and always the same. Due to a limited Raman gain, an EDFA amplifier is embedded into the card to generate a higher total gain. An embedded EDFA gain block provides a first amplification stage, while the mid stage access (MSA) is used for DCU loss compensation.

The OPT-RAMP-CE card is a 20 dBm output power, gain-enhanced version of the OPT-RAMP-C card and is optimized for short spans. The OPT-RAMP-C and OPT-RAMP-CE cards can support up to 80 optical transmission channels at 50-GHz channel spacing over the C-band of the optical spectrum (wavelengths from 1529 nm to 1562.5 nm). To provide a counter-propagating Raman pump into the transmission fiber, the Raman amplifier provides up to 500 mW at the LINE-RX connector. The OPT-RAMP-C or OPT-RAMP-CE card can be installed in Slots 1 to 5 and 12 to 16, and supports all network configurations. However, the OPT-RAMP-C or OPT-RAMP-CE card must be equipped on both endpoints of a span.

The Raman total power and Raman ratio can be configured using CTC. The Raman configuration can be viewed on the Maintenance > Installation tab.

The features of the OPT-RAMP-C and OPT-RAMP-CE card include:

• Raman pump with embedded EDFA gain block

• Raman section: 500 mW total pump power for two pump wavelengths

• EDFA section:

  • OPT-RAMP-C: 16 dB gain and 17 dB output power

  • OPT-RAMP-CE: 11 dB gain and 20 dB output power

Caution

LASER ENERGY - EXPOSURE NEAR APERTURE MAY CAUSE BURNS

The single-slot RAMAN-CTP and RAMAN-COP cards support counter and co-propagating Raman amplification on very long unregenerated spans.

The cards manage up to 96 ITU-T 50-GHz spaced channels over the C-band of the optical spectrum (wavelengths from 1528.77 nm to 1566.72 nm). The counter-propagating RAMAN-CTP card is the primary unit. The co-propagating RAMAN-COP card is the secondary unit and can be used only when the counter-propagating unit is present. The RAMAN-CTP card and the RAMAN-COP card must be installed in adjacent slots for Cisco NCS 2000 Series chassis. For example, you can install in Slots 2 and 3, 4 and 5, or 6 and 7 in NCS 2006 . However, these adjacent slots must not be used to install two RAMAN-CTP or two RAMAN-COP cards.

The RAMAN-CTP card can be calibrated either manually or using the Automatic Raman Pump Amplification (ARPC) procedure from the Card tab in the Provisioning panel in CTC. When the RAMAN-COP card is used, the RAMAN-CTP card can be calibrated only using the manual option. ARPC is supported only in the NCS Flex package.

The features of the RAMAN-CTP and RAMAN-COP cards include:

• Raman section: 1000 mW total pump power for four pumps and two wavelengths

Note	OPT-EDFA-35 card is supported only in NCS Flex and NCS SSON packages.

The OPT-EDFA-17, OPT-EDFA-24, and OPT-EDFA-35 cards are C-band DWDM EDFA amplifiers and preamplifiers. The cards are true variable gain amplifiers, offering an optimal equalization of the transmitted optical channels over a wide gain range. They support 96 channels at 50-GHz channel spacing in the C-band (that is, 1528.77 to 1566.72-nm wavelength range). The OPT-EDFA-17 and OPT-EDFA-24 cards deliver 20-dBm output powers and the OPT-EDFA-35 card delivers +23-dBm output power. These cards do not contain mid-stage access loss for a Dispersion Compensation Unit (DCU). The cards provide a noise-figure optimized version of the EDFA amplifiers to cope with new modulation formats like PM-DQPSK, which do not need dispersion compensation. To control gain tilt, a VOA is used. The amplifier module also includes the OSC add (TX direction) and drop (RX direction) optical filters.

The OPT-EDFA-17, and OPT-EDFA-24 cards share the same hardware platform and firmware architecture, but they differ in their operative optical gain range, which is 17 and 24 dB respectively.

The OPT-EDFA-35 card includes two identical amplification sections to serve two fiber directions simultaneously. Each section has a switchable gain range that allows its usage over a wide gain range. The OPT-EDFA-35 card is bidirectional. The card acts on both pairs of fibers entering and exiting from the node.

The OPT-EDFA-35 card has two possible gain ranges: gain range 1 from 12–24, gain range 2 from 20–35. The card also has extended gain range up to 40 dB without tilt control.

The OPT-EDFA-35 card is managed in a similar way as the OPT-EDFA-17 and OPT-EDFA-24 cards. For each EDFA unit inside the OPT-EDFA-35 card, the following settings are allowed:

• Configuration of PRE or BST role
