Ihe fọrọ nke nta ka ọ bụrụ afọ anọ gara aga, otu ndị na-ere ahịa 13 hibere QSFP-DD (Quad Small Form-factor Pluggable Double Density) Otu nkwekọrịta multi-source (MSA), na ebumnuche nke ịmepụta transceiver anya QSFP okpukpu abụọ.N'ime afọ kemgbe ntọala ya, otu MSA ekepụtala nkọwapụta maka QSFPs iji kwado ngwa Ethernet 200- na 400-Gbit/sec.
Teknụzụ ọgbọ gara aga, modul QSFP28, na-akwado 40- na 100-Gbit Ethernet ngwa.Ha nwere ụzọ eletrik anọ nwere ike ịrụ ọrụ na 10 ma ọ bụ 25 Gbits / sk.Otu QSFP-DD ewepụtala nkọwapụta maka ụzọ asatọ na-arụ ọrụ ruo 25 Gbits/sekọnd ma ọ bụ 50 Gbits/sec—na-akwado 200 Gbits/sec na 400 Gbits/sec, n'otu n'otu, na mkpokọta.
Na Julaị 2019 otu QSFP-DD MSA weputara ụdị 4.0 nke nkọwa njikwa njikwa nkịtị (CMIS).Otu ahụ wepụtakwara ụdị 5.0 nke nkọwa ngwaike ya.Otu ahụ kọwara n'oge ahụ, "Ka nkuchi nke 400-Gbit Ethernet na-eto, CMIS e mere iji kpuchie ụdị ụdị modul dị iche iche, ọrụ na ngwa, sitere na mgbakọ ọla kọpa na-agafe agafe ruo na DWDM na-ejikọta ọnụ. ] modul.Enwere ike iji CMIS 4.0 dị ka ihe jikọrọ ọnụ site na ụdị 2-, 4-, 8-, na 16-lane ndị ọzọ, na mgbakwunye na QSFP-DD."
Na mgbakwunye, otu ahụ kwuru na ụdị 5.0 nke nkọwa ngwaike ya “gụnyere njikọ ngwa anya ọhụrụ, SN na MDC.QSFP-DD bụ ihe nrịbama modul data etiti 8-lane izizi.Sistemu emebere maka modul QSFP-DD nwere ike ịlaghachi azụ-dakọtara na ụdị QSFP dị ugbu a ma na-enye mgbanwe kachasị maka ndị ọrụ njedebe, ndị na-emepụta ikpo okwu netwọkụ na ndị mmekọ.
