Following are cabling options and recommendations:
v
Connect the 3-meter integrated single mode transceiver cable directly to a female-terminated connector
in a patch panel or patch cable using a key-up/key-down MPO/MTP coupler.
v Use female-to-female patch cable with the following specifications:
– Single-mode (not OM3 MMF or OMM MMF)
– MTP/MPO 1x12 fiber
– MTP female angled polished connector (APC)
– Key-up/key-up connectors for polarity
All 16 ICL ports can be used for 2 km distances when we configure 20 buffer credits are configured per
virtual channel.
4x32 Gbps 2 km LWL QSFPs
The 2 km 4x32 Gbps LWL QSFP28, is a hot-swappable, low-voltage (3.3 V) digital diagnostic optical
transceiver that supports high-speed serial links over parallel single-mode optical fibers at signaling rates
up to 4
×
28.05 Gbps. This is a multi-rated CWDM4 QSFP28 transceiver with a duplex LC connector. It
supports up to 2 km link length using duplex single mode fiber.
