Cisco e lumellanang le 100GBASE-SR4 QSFP28 850nm 100m DOM MPO-12/UPC MMF Optical Transceiver Module, e phatlohang ho isa ho 4 x 25G-SR ka DDM
Tlhaloso
+ Mojule oa Cisco QSFP-100G-SR4-S o lumellanang le QSFP28 Optical Transceiver o etselitsoe ho sebelisoa ho 100GBASE Ethernet throughput ho fihlela ho 100m holim'a faeba ea multimode ea OM4 (MMF) ho sebelisoa bolelele ba bolelele ba 850nm ka sehokelo sa MTP/MPO-12. Transceiver ena e latela maemo a IEEE 802.3bm 100GBASE-SR4 le CAUI-4. Mesebetsi ea tlhahlobo ea dijithale e boetse e fumaneha ka sebopeho sa I2C, joalo ka ha ho boletsoe ke QSFP28 MSA, ho lumella phihlello ho liparamente tsa ts'ebetso tsa nako ea sebele. Ka likarolo tsena, transceiver ena e bonolo ho e kenya, e chesang e ka fetoloang e loketse ho sebelisoa lits'ebetsong tse fapaneng, joalo ka litsi tsa data, marang-rang a khomphutha a sebetsang hantle, lits'ebetso tsa mantlha tsa khoebo le tsa lera la kabo.

OP-QSFP28-01 e etselitsoe ho sebelisoa ka lihokelo tsa 100 Gigabit ka motsotsoana holim'a faeba ea mekhoa e mengata.
Li lumellana le QSFP28 MSA le IEEE 802.3bm. Karolo ea transmitter ea optical ea transceiver e kenyelletsa sehlopha sa VCSEL (Vertical Cavity Surface Emitting Laser) sa likanale tse 4, buffer ea ho kenya ea likanale tse 4 le mokhanni oa laser, li-monitor tsa tlhahlobo, li-block tsa taolo le tsa bias. Bakeng sa taolo ea mojule, sebopeho sa taolo se kenyelletsa sebopeho sa Two Wire Serial sa matšoao a oache le data. Li-monitor tsa tlhahlobo bakeng sa
