2 km LWL QSFPs
All 16 ICL ports can be used for 2km distances when we configure 20 buffer
credits are configured per virtual channel.
The 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 fibers at signaling rates up to 4
× 14.025 Gbps. The QSFP is integrated with a
3 m ribbon fiber cable with a male MTP 1x12 connector. The QSFP supports 2 km
link length on parallel single-mode fiber.
1 - MTP 1x12 fiber male connector
2 - Integrated 3-meter MTP cable
3 - Transceiver with pull-tab
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-down connectors for polarity
Time and items required
The installation or replacement procedure for one transceiver takes less than 5
minutes. Ensure that the following items are available:
v Required number of compatible power cables
v Required number of supported IBM-branded transceivers
v Required number of compatible fiber-optic cables
v Optical transceiver extraction tool (for 10 Gbps transceiver only)
Note: Most devices come with a transceiver extraction tool and holster. The
extraction tool is designed to remove transceivers from modules where the space
is limited.
