The JDSU Datacom Small Form Factor Pluggable (SFP) transceiver product families provide high-speed serial links at signaling rates of up to 4.25 Gb/s, which conform either to the Gigabit Ethernet 802.3 or American National Standards Institute's (ANSI) Fibre Channel, FC- PI specification. All Datacom SFP transceivers are Class 1 laser safe and have EMI emissions below residential FCC Class B.

This family of product exceeds MSA compliance with broader supply and laser voltage tolerances, interoperability with legacy devices that use CD lasers, and interoperability with other standards-compliant transceivers at link distances up to 80 km. All 850 nm products use enhanced oxide lasers and transmit optical subassemblies designed for reliability and extra-long-life operations. The JSH family expands upon the original JSP/JSM family features with extended temperature operation and a bail latch for high density host card packaging. JSH products are respectively product-enhanced with SFF 8472 compliant digital diagnostic monitoring features.
