RXT-6402 High-Speed Transceivers Pull-Tab Orientation (How to Insert them Correctly)

Modern High-Speed transceivers tend to stick up to an inch (>2 cm) outside of their cage, so it is important to know how to insert them correctly (orientation) and not to push them too far.

RXT-6402 connector panel image showing the correct orientation of the pluggable transceivers

The image depicts the correct orientation for all pluggable transceivers supported by VeEX's RXT-6402 Dual 400G test module. For high-speed transceivers, users may use the pull-tabs, or LC connector direction, as a reference for their correct orientation.

  • On certain test sets, the This connector panel marking indicates the proper orientation for the transceiver's pull-tab, to prevent it from being inserted incorrectly (pull tab up) and This connector panel marking indicates the proper orientation for the transceiver's pull-tab, to prevent it from being inserted incorrectly (pull tab down) icons may be printed on the connector panel, next to the transceiver slot (cage), to remove the guesswork and help users. The This connector panel marking indicates the proper orientation for the transceiver's pull-tab, to prevent it from being inserted incorrectly mark indicates Front view of an QSFP-DD (or QSFP56/28) with the pull-tab up orientation) or Front view of an SFP-DD (or SFP56/28) with the pull-tab up orientation), while This connector panel marking indicates the proper orientation for the transceiver's pull-tab, to prevent it from being inserted incorrectly indicates Front view of an QSFP-DD (or QSFP56/28) with the pull-tab down orientation) or Front view of an SFP-DD (or SFP28) with the pull-tab down orientation).
  • Note that AOC/DACs, 100G SFP-DD, 25G/32G SFP28 transceivers come with Pull-Tabs while 1G/10G/16G SFP+ (and some SFP28) come with traditional Bail Clasp (pull lever) with the colored part on the opposite side. The panel markings only depict the orientation for pull tabs. The orientation of the colored part of the bail clasp is shown above the module, for reference. In this case, if the SFP case label is marked This connector panel marking indicates the proper orientation for the transceiver's pull-tab, to prevent it from being inserted incorrectly insert the traditional SFP with the clasp up SFP+ with bail clasp oriented up (the bail clasp opens up downwards and becomes a bottom pull-tab). If marked This connector panel marking indicates the proper orientation for the transceiver's pull-tab, to prevent it from being inserted incorrectly, insert the SFP in this orientation SFP+ with bail clasp oriented down (the bail clasp opens upwards, which is equivalent to a top pull-tab)
  • QSFP28, QSFP-DD and QSFP-DD800 transceiver heads may protrude more than one inch (2.54 cm) outside of the cage (slot), DO NOT try to force them in any further.

Always remove QSFP-DD, QSFP56, QSFP28 and SFP-DD transceivers from the test set before storing it in the carrying case. Store the transceivers in their transport boxes.
