FIGURE 19 DCX 8510 full mesh ICL topology
Using Brocade 2 km LWL QSFPs
Up to 10 ICL ports using the 2km ICL QSFP are supported in a DCX 8510 backbone switch at the two km distance, which requires
conguring 16 buer credit per virtual channel. The 10 ICL limit is based on the number of buers. If the 2km QSFPs are used at
shorter distances, then more ICLs can be used.
The Brocade 2 km LWL QSFP, is a hot-swappable, low-voltage (3.3 V) digital diagnostic optical transceiver that supports high-speed
serial links over parallel single-mode optical bers at signaling rates up to 4×14.025 Gbps. The QSFP is integrated with a 3-meter
ribbon ber cable with a male MTP 1 x 12 connector. The QSFP supports 2 km link length on parallel single-mode ber.
