Eaton Tripp Lite Series 1000BASE-SX SFP Transceiver Module, LC Duplex Multimode Fiber MMF, 1.25 Gbps, 850 nm, 1804 Feet / 550 Meter Length, 3-Year Warranty (N286-01G-SX-G)

SFP Transceiver Designed for Connection to Your Network Switch or Server
This SFP transceiver allows you to connect a multimode fiber optic cable to a 1.25 Gbps network router, server or switch. It transmits data up to 1804.4-ft. (550 m) using an 850 nm wavelength. The zinc housing protects against electromagnetic interference (EMI) and excessive power dissipation.

Functionally Equivalent to Cisco GLC-SX-MMD Transceiver Module
The MSA-compliant N286-01G-SX-G functions just like the equivalent Cisco GLC-SX-MMD and other OEM transceiver modules and is manufactured to meet or exceed Cisco specifications. You can use this transceiver with any compatible network router, server or switch and receive the same performance as the GLC-SX-MMD.

Hot-Swappable for Installation Without Network Interruption
This input/output device is fully hot-swappable, so you can install it without a potentially costly 1.25 Gbps network shutdown or device reboot. Just plug the SFP end of the transceiver into your network device. The other end has an LC duplex connector to link with multimode fiber optic cable (sold separately).

Supports Digital Diagnostic Monitoring (DDM) for Real-Time Status Monitoring
DDM support lets you keep track of various operating status in real time including transceiver temperature, input and output power, and supply voltage.
