Compliance
The JDSU JSH-12L1DD1 SFP transceivers are hot-pluggable, 3.3 V duplex-LC
transceivers that provide a high-speed serial link at a signaling rate of up to 2.125
Gbps. They are designed for use in ANSI Fibre Channel and Gigabit Ethernet ap-
plications. These transceives provide the LC optical receptacle that is compatible
with the industry-standard LC connector.
The transceiver consists of an optical subassembly housing the transmitter and
receiver, and an electrical subassembly. All are packaged together with a top metal
cover and bottom shield. The optical subassembly consists of two parts. The trans-
mitter side has a high-performance, 1310 nm, back-facet monitor. The receiver
side has an InGaAs PIN and a preamplifier.
The digital diagnostic monitoring (DDM) interface uses the same two-wire serial
ID interface defined in the SFP MSA specification. The standard serial ID infor-
mation is located at address A0h. Using address A2h, the user can monitor trans-
ceiver parameters, including temperature, voltage, laser bias current, laser power,
and receiver power. Alarms and warnings are provided when the monitored pa-
rameters exceed predefined threshold values. All transceivers include a loss-of-
signal-detect circuit, which provides a TTL logic high output when an unusable
input optical signal level is detected.
