A tighter specification DFB laser (part #1243TAFA) may be supplied instead of the MLM laser. The DFB
laser meets all the requirements of the MLM laser and DFB requirements in GR-253-CORE, Issue 2,
December 1995.
† The universal optical connector (UOC) buildout assembly consists of a faceplate-mounted block
assembly and either 0 dB, 5 dB, 10 dB, or 15 dB buildout in either ST, SC, or FC-type connectors. ST
universal buildout does not apply to 22G-U.
