TP-Link SM9110-SR4 100GBASE-SR4 QSFP28 Transceiver

A Short-Reach Fibre Link for 100GbE Networks The TP-Link SM9110-SR4 connects compatible 100GbE QSFP28 equipment across multimode fibre. Its 850nm SR4 optics and MPO/MTP-12 connector suit short-reach links between appropriate switches or network equipment, with manufacturer reach of up to 100M on OM4 fibre. Digital Diagnostic Monitoring provides useful module information through a supporting host, while the hot-pluggable design simplifies planned installation and replacement. Highlights 100GbE Optical Connectivity 100GBASE-SR4 QSFP28 module for compatible host ports. Up to 70M on OM3 or 100M on OM4 multimode fibre. Match the Fibre Path 850nm optics with an MPO/MTP-12 connector. Requires a correctly specified multimode fibre assembly and matching remote optics. Module Visibility Digital Diagnostic Monitoring through a supporting host. Hot-pluggable module powered from the host port. Key Features Keep the Uplink Appropriate to the Network A 100GbE optical connection is useful where the switching and traffic justify that link capacity. The module provides the physical optical interface; it does not upgrade a slower port or increase the capacity of unrelated parts of the network. Match the host’s supported transceiver list, port speed and operating mode before ordering. Specify the Cable as Carefully as the Module SR4 uses parallel multimode fibre through an MPO/MTP-12 connection. It is not a duplex LC module. Choose the correct fibre grade, connector gender, polarity and end-to-end optical path for the equipment. The stated 100GbE reach is up to 70M on OM3 and 100M on OM4 under the manufacturer’s conditions. Monitor the Optical Link Digital Diagnostic Monitoring can expose supported temperature, voltage and optical information to the host. These readings help a Specialist investigate a link problem alongside interface counters and fibre inspection. The information actually displayed depends on the switch or other equipment and its software. Plan Around the Supplied Hardware Revision Current manufacturer documentation includes a dual-rate 100G/40G hardware revision. That does not establish that every available unit supports the same 40GbE mode. Confirm the supplied hardware version and the host’s compatibility before using 40GbE; do not assume that a QSFP+ cage or third-party switch will accept it automatically. Summary The SM9110-SR4 is a focused choice for compatible short-reach 100GbE multimode links. Correct host support, fibre specification and remote optics matter as much as the headline port speed. Frequently Asked Questions Does it fit an SFP+ port?ExpandCollapse No. This is a QSFP28-form-factor module. It does not fit an ordinary SFP or SFP+ cage. Can I use a duplex LC patch cable?ExpandCollapse No. The optical connection is MPO/MTP-12. Specify the correct multimode fibre assembly, connector gender and polarity for the complete link. What distance does it support at 100GbE?ExpandCollapse The manufacturer documents up to 70M on OM3 and 100M on OM4 multimode fibre. Cable quality, connections and the complete optical budget still need to be suitable. Is 40GbE operation guaranteed?ExpandCollapse No. The current 1.20 documentation describes 40GbE operation, but the supplied hardware revision and host support must be confirmed before relying on that capability. Is the fibre cable included?ExpandCollapse The product is one optical transceiver. Fibre cabling and the remote transceiver are separate unless a specific bundle says otherwise. Magbasa pa
