Avago Technologies’ HFBR-5911L/AL optical transceiver supports high-speed serial links over multimode optical fiber at signaling rates of up to Gb/s. Compliant with the Small Form Factor SFF Multi Source Agreement MSA for 2 x 5 pin LC Duplex transceivers and IEEE specification for Gigabit Ethernet GbE links 1000BASE-SX , the part is interoperable and interchangeable with other conformant devices. Supported Gigabit Ethernet link lengths are described in Table 1, but the transceiver can also be used for other high-speed serial applications, such as iSCSI.

The SFF package of the HFBR-5911L/AL allows designers of Gigabit Ethernet networking equipment to maximize their use of available board space.
