Compatible 1000BASE-SX 1.25G SFP Transceiver LC Duplex Multimode 850nm Fiber without DDM, up to 550M

Small form factor pluggable (SFP) transceivers are used in data communication applications where it's often installed on networking hardware (switches, media converters, etc.) to connect a fiber optic cable. Due to its higher port density, its support of different speeds, and its ability to use various types of fiber cables, the SFP transceiver is often used by OEMs when compared to a standard GBIC (Gigabit Interface Converter). The SFP transceiver is hot-pluggable and compact, making it ideal for use in network applications. SFP transceivers come with various specifications, allowing users to taylor to their specific preference.

The Leapmicro series SFP transceivers from PI Manufacturing are designed for use with Cisco equipment. Equivalent to the Cisco GLC-SX-MM, this transceiver is 100% compatible and fully tested to meet or exceed OEM specifications. Specific OEM configuration data is loaded onto the EEPROM of the transceiver, allowing it to operate identically to the OEM's transceiver. The transceiver complies with Multi-Source Agreement (MSA) standards.

SFP review

SFP's say that they are cisco compatible. I have tested the units in a Cisco 3750, Cisco 300 small business switch 8port and 24 port, HP bladed switch and 1000 Gb MC-SFP-1 transceivers. The units have worked In all of the units with no problems. For the price this are unbeatable.
