Komodo Fiber Reference Guide

Board Diagnostic

The reference design can be used as a board diagnostic to verify the board interfaces. The external

board interfaces are verified through and external loopback method. To populate the external

loopbacks a specific fixtures are required. Some of the fixtures are proprietary to KAYA

Instruments. Please contact KAYA Instruments representative for availability of the fixtures.

For SFP+ loopback, optical SFP+ loopback fixtures are required. Figure 13 shows the optical SFP+

loopback fixture.

Figure 13: SFP+ loopback fixture

For QSFP loopback, optical QSFP loopback fixture is required. Figure 14 shows the optical QSFP

loopback fixture.

Figure 14: QSFP loopback fixture

For DDR3 SODIMM test a MT8KTF51264HZ-1G6E1 SODIMM from Micron is required as

shown in Figure 15.
