Note For hardware specifications, see the “A.5.1 OPT-PRE Amplifier Card Specifications” section on
page A-14.
Note For OPT-PRE card safety labels, see the “4.2 Class 1M Laser Safety Labels” section on page 4-3.
The OPT-PRE is a C-band, DWDM, two-stage erbium-doped fiber amplifier (EDFA) with midamplifier
loss (MAL) that can be connected to a dispersion compensating unit (DCU). The OPT-PRE is equipped
with a built-in variable optical attenuator (VOA) that controls the gain tilt and can also be used to pad
the DCU to a reference value. You can install the OPT-PRE in Slots 1 to 6 and 12 to 17. The card is
designed to support up to 80 channels at 50-GHz channel spacing. The OPT-PRE features include:
• Fixed gain mode with programmable tilt
• True variable gain
• Fast transient suppression
• Nondistorting low-frequency transfer function
• Settable maximum output power
