907-CWDM (CWDM Optics Card)

Card P/N
Config. Dwg.
The 907-CWDM optics card shown in Figure 6-5 is a two-channel CWDM optical add/drop multiplexer
(OADM). The 907-CWDM is able to add or drop individual 1471 nm and 1491 nm CWDM wavelengths to an
existing 1310/1550 nm (wider band) WDM signal by daisy chaining to the existing fiber link.
The 907-CWDM optics card delivers cost savings by upgrading an existing 907 multiplexer system operating
at 1310/1550 nm wavelengths. For example, with a 907-CWDM optics card, a 907Plus multiplexer
motherboard using a bidirectional transceiver operating at 1310/1550 nm wavelengths can be upgraded by
adding a 907-GBE Gigabit Ethernet media converter card that uses a transceiver operating at 1471/1491nm
wavelengths.
To daisy chain the 907-CWDM optics card, the bypass port ST1B should be connected to a 1310/1550 nm
907 card and the common port ST2B should be connected to the external cable system per the configuration
drawing.
The standard 1471 nm and 1491 nm CWDM wavelengths used on the 907-CWDM optics card can be
changed to other CWDM wavelengths upon request, but only the 1471/1491 nm version can be daisy chained
with existing 1310/1550 nm systems.
