Description
These JDSU SFPs are integrated fiber optic trans-
ceivers that provide a high-speed serial link at a sig-
naling 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 dis-
tance of 5 km and is available with blue color identi-
fication 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 electri-
cal 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 inter-
face at the SFP connector.
Encoded (8B/10B) [3], [4], 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.
