These JDSU SFPs are integrated fiber optic transceivers that provide a high-speed serial link at a signaling rate up to 4.25 Gb/s. They conform to the American National Standards Institute’s (ANSI) Fibre Channel, and SFF-8472 specifications.

The JSH-42L3AD3-5 supports a maximum fiber distance of 5 km and is available with blue color identification or gray color identificaiton (JSH-42L3AD3-5G). The JSH-42L3AD3-20 supports a maximum fiber distance of 20 km. These transceivers operate on singlemode fiber only.

The transceiver is ideally suited for Fibre Channel applications which include point to point links as well as Fibre Channel Arbitrated Loop (FC-AL). It can also be used for other serial applications where high data rates are required. This specification applies to a hot-pluggable (SFP) module which is an electrical surface-mount connector assembly.

The transceiver features a microprocessor with imbedded non-volatile RAM. Vital product data is stored in the NVRAM and several optical and electrical characteristics of the transceiver are computed “Real-Time” with the results written to memory. This data can all be accessed by a two-wire serial interface at the SFP connector.

Encoded (8B/10B), serial differential signals traverse the connector interfacing the transceiver to the host card. The serial data modulates the laser and is sent out over the outgoing fiber of a duplex cable.

The transceiver is a certified Class 1 laser safe product. The optical power levels, under normal operation, are at eye safe levels. Optical fiber cables can be connected and disconnected without shutting off the laser transmitter.

The transceiver is also compliant with the RoHS Directive from the European Union - Directive 2002/95/EC on the Restriction Of use of certain Hazardous Substances. The largest change with optical transceivers comes with the removal of all lead-based parts and soldering. Now it is a lead-free part.
