While Cisco has an existing portfolio of QSFP-100G transceivers for SMF for 500 m, 2 km, 10 km, 25 km, 30 km, and 40 km reaches, the QSFP-100G-ZR4-S transceiver now adds 80 km reach..\u003cbr\u003e\u003cbr\u003eThe QSFP-100G-ZR4-S enables 100Gb at distances reaching 80km to connecting: wireless access locations to core networks, distant enterprise locations to each other, widely separated regional data centers together, or remote service provider buildings to central offices.\u003cbr\u003e\u003cbr\u003eExisting options for 100G connectivity reaching 80km are primarily based on specific chassis, line cards, or large modules. As a result, these solutions tend to require lots of power or take up large amounts of space, resulting in higher costs to deploy and operate. The Cisco QSFP-100G-ZR4-S solution operates with relatively low power and the modules fit into standard QSFP28 ports, resulting in a cost effective solution.\u003cbr\u003e\u003cbr\u003eThe QSFP-100G-ZR4-S operates in the O-band optical spectrum where fiber optic dispersion is minimal, using traditional direct-detect transceiver technology with NRZ (Nonreturn to Zero) modulation. A SOA (Semiconductor Optical Amplifier) is used to overcome the optical attenuation of the long reach. The lasers in the QSFP-100G-ZR4-S leverage the traditional LAN WDM grid lasers found in other QSFP-100G transceivers. As like many other QSFP28 transceivers, the QSFP-100G-ZR4 has 4 optical and electrical lanes, where each lane is operating at 25Gb. The block diagram in Figure 4, shows the transmit signal of the QSFP-100G-ZR4-S consisting of four lasers each operating at a different wavelength that are muxed into a single optical fiber, and on another fiber in the receive path the optical signal is amplified by an SOA and then demuxed in 4 unique wavelengths and fed into four receivers.\u003cbr\u003e\u003cbr\u003eApplications today requiring QSFP-100G-ZR4-S include: \u003cbr\u003e \u003cul\u003e \u003cli\u003eWireless: aggregating 4G and 5G fronthaul and midhaul routers\u003c\/li\u003e \u003cli\u003eService provider: reaching rural and remote COs\u003c\/li\u003e \u003cli\u003eData center: connecting regional centers\u003c\/li\u003e \u003cli\u003eEnterprise: linking metro offices\u003c\/li\u003e \u003c\/ul\u003e A typical installation involving QSFP-100G-ZR4-S might include switches or routers.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eProduct Type: QSFP28\u003cbr\u003e\n\u003c\/li\u003e\n\u003ch4\u003e\u003cstrong\u003eTechnical Information\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cli\u003eApplication\/Usage: \u003cul\u003e\n\u003cli\u003eData Networking\u003c\/li\u003e\n\u003cli\u003eOptical Network\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cbr\u003e\n\u003c\/li\u003e\n\u003ch4\u003e\u003cstrong\u003eInterfaces\/Ports\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cli\u003eTotal Number of Ports: 1\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eConnector Type: LC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eInterfaces\/Ports Details: 1 x LC Duplex 100GBase-ZR4 Network\u003cbr\u003e\n\u003c\/li\u003e\n\u003ch4\u003e\u003cstrong\u003eMedia \u0026amp; Performance\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cli\u003eMedia Type Supported: Optical Fiber\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eFiber Mode Supported: Single-mode\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eEthernet Technology: 100 Gigabit Ethernet\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eNetwork Technology: 100GBase-ZR4\u003cbr\u003e\n\u003c\/li\u003e\n\u003ch4\u003e\u003cstrong\u003ePhysical Characteristics\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cli\u003eForm Factor: Plug-in Module\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/div\u003e","brand":"Cisco Systems, Inc","offers":[{"title":"Default Title","offer_id":50316198871397,"sku":"QSFP100GERLS","price":3464.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0885\/4392\/0485\/files\/1069745270.jpg?v=1787262710","url":"https:\/\/itosolutions.net\/products\/cisco-qsfp28-module-qsfp-100g-erl-s","provider":"ITO Solutions, Inc.","version":"1.0","type":"link"}
