Add, replace or upgrade SFP modules on Gigabit fiber equipment. The SFPGLCLHSMST Cisco Compatible Gigabit Fiber SFP Transceiver Module SM/MM LC is built to comply with MSA (Multi-Sourcing Agreement) standards to offer a cost-effective way to add, replace or upgrade an SFP slot on your Gigabit fiber networking equipment or fiber media converter. Supporting a 1000Base-LX/LH network with data rates up to 1.25 Gbps, this LC SFP/Mini-GBIC module can be installed into any fiber networking device with an MSA or Cisco compliant SFP port. The SFP transceiver supports both single-mode and multi-mode LC ports, with a single-mode distance of 10 km (6.2 mi.) and multi-mode distance of 1.5 km (.9 mi.). Delivering both convenience and scalability, this fiber transceiver is fully hot-pluggable, which enables you to install the module without interrupting network traffic or requiring a device reboot. This 1300nm single-mode/multi-mode SFP module is compatible with the Cisco GLC-LH-SM transceiver. Also a perfect accessory for the StarTech.com PEX1000SFP PCI Express Open SFP NIC (PEX1000SFP), or ET1110PSE Gigabit POE Open SFP Media Converter (ET1110PSE) products.
