The Cisco Catalyst 9300 Series Switches support optional network modules for uplink ports. The default switch configuration does not include the network module.

The Cisco Catalyst 9500 Series Switches support optional network modules for uplink ports only on the 40-port 10 Gigabit Ethernet switch. The default switch configuration does not include the network module.

This Cisco QSFP-40G-ER4 compatible QSFP+ transceiver provides 40GBase-ER4 throughput up to 30km over single-mode fiber (SMF) at a specified wavelength between 1270nm and 1330nm using a LC connector. Digital optical monitoring (DOM) support is also present to allow access to real-time operating parameters. Our transceiver is guaranteed to be 100% compatible with the equivalent Cisco transceiver. This easy to install, hot swappable transceiver has been programmed, uniquely serialized and data-traffic and application tested to ensure that it will initialize and perform identically. It is built to meet or exceed the specifications of Cisco, as well as to comply with multi-source agreement (MSA) standards to ensure seamless network integration. We stand behind the quality of our products and proudly offer a limited lifetime warranty. Trade Agreements Act (TAA) versions of this part are available upon request.

Instant Connectivity and Reliable PerformanceThe NETGEAR Gigabit Unmanaged Switch series helps your business cost-effectively expand your network to Gigabit speeds and higher port counts. The GS516PP joins the series and offers 16 PoE+ ports to power high-power PoE devices. With a total PoE power budget of 260W, deploy denser PoE+ devices to a single switch rather than multipleThe GS516PP is energy efficient, built to last, and rigorously tested to provide the reliability your business needs. 802.1p traffic prioritization and jumbo frame support allow for seamless integration with more sophisticated networks.Powerful and Energy EfficientIdeal for powering and connecting VoIP phones, wireless access points, IP Cameras and IoT devices. Desktop or rackmount for flexible placement. The GS516PP gives you a highly cost-effective and powerful switch with the best cost/PoE budget ratio.NETGEAR Unmanaged Switches support the latest Energy Efficient Ethernet (IEEE 802.3az) standard, which reduces energy consumption when there is light traffic on an active port or when there is no link or no activity detected. It can further save energy when a short cable is used.

Gigabit Media Converter | SFP to RJ45 (Cat6) | MTBF: 500,000+hrs @ 50°C | 12V-56VDC | Works with 100 Mbps SFPsAn industrial media converter that converts fiber to copper at a network endpoint.A Flexible Solution Covering Different RequirementsThis media converter features an open SFP slot for any standard gigabit SFP to be used for the incoming fiber connection and is easily deployed across applications or fiber cable types. Accepts terminal block power or coaxial power connectors with the barrel plug adapter, allowing the product to be hardwired or powered using an external power supply (not included), which does not require professional installation. It can be powered using 12V-56V DC for solar, automotive, rail, and other applications and requires a minimum 12V power input. Includes hardware for DIN rail or wall mounting.For Mission-Critical ApplicationsDesigned with IP-30 housing and has an MBTF of >500;000 hrs (Telcordia/Bellcore) at 50°C and an operating temperature range of include -40 C to 75 C for durability; it's rated to various vibration, shock, and free-fall standards:• Vibration: EN 60068-2-6• Shock: EN 60068-2-27• Free-Fall: EN 60068-2-32The IMC1GSFP is backed by a StarTech.com 2-year warranty and free lifetime technical support.The StarTech.com Advantage
