• SONET OC-1, OC-3, OC-12, and OC-48 rates are supported
• Operation at 1310 or 1550 nm
• Uncooled, field proven, isolated distributed feedback
(DFB) laser
• -40 to 85 °C operation
Applications
• High speed, long haul fiberoptic links
for voice, data, and digital video
• Metropolitan area networks
• Wide area networks
The JDSU 54TM series optical transmitter module is designed for use in
telecommunication systems and high speed data communications applications.
The transmitter is optimized for SONET OC-1, OC-3, OC-12, and OC-48. It is
compatible with the multisource agreement (MSA) specification, which defines a
uniform package, pin function, and common optical and electrical characteristics.
The 54TM transmitter meets all GR-253-CORE requirements and ITU-T G.957
and G.958 recommendations.
Compliance
• Telcordia GR-253-CORE
• ITU-T G.957 and ITU-T G.958
The 54TM features a unique design that uses fewer parts and completely
eliminates the thermoelectric cooler, resulting in cost savings and lower power
consumption.

1. All minimum and maximum parameters are specified end-of-life within the overall, relevant operating temperature range.
The typical values are referenced to 25 °C (nominal power supply) beginning of life.
The operating conditions are: Vcc = 4.75 to 5.25 V DC
Vee = 0 V DC
Line bit rate: 2.48832 Gb/s ±20 ppm

5. Measured at end of life, over entire operating temperature, power supply range, and measured into a 25 dB minimum optical return loss.

8. This note applies only to the 1310 nm version. Path penalty shall include total path dispersion and maximum R point reflectance, (40 km assumed). Measured at center
wavelength = 1310 nm. Using 1310 source on non-dispersion shifted fiber at 250 ps/nm, (assuming a DFB laser). Using 1310 source on dispersion shifted fiber at -300 ps/nm,
assuming a DFB laser.
9. This note applies only to the 1550 nm version. Path penalty shall include total path dispersion and maximum R point reflectance, (80 km assumed). The penalty when
operating on Dispersion-shifted fiber is specified as only 1.0 dB. Measured at center wavelength = 1550 nm. Using 1550 source on non-dispersion shifted fiber at 1600 ps/nm
(assuming a DFB laser).
10.Measured into a 25 dB minimum optical return loss. Maximum optical TX jitter allowed by Bellcore and ANSI is .01 UI RMS (4 ps RMS) and 0.1 UI p-p (40 ps p-p). A
portion of this jitter requirement has been allocated to the opto transmitter module as noted.
The maximum RMS jitter contribution from the Optic TX module shall be less than this value. This should be tested with an STS-48 source with less than 2.8 ps RMS jitter
to ensure that overall ANSI/Bellcore TX jitter generation requirements are met (with a small additional system margin factored in). Jitter addition is expected to be RMS:
The maximum peak-to-peak jitter contribution from the Optic TX module shall be less than this value. This should be tested with an STS-48 source with less than 20 ps p-p
jitter to ensure that overall ANSI/Bellcore TX jitter generation requirements are met (with a small additional system margin factored in). Jitter addition is expected to be
primarily a pattern dependent non-linear algebraic addition, with the highest pp jitter levels measured in the STS-48 section overhead region. Care must be taken to note
the jitter signs (polarity) and shape (jitter vs. STS-48 frame position) of the STS-48 source, and the additive jitter due to the optic TX module and any other required test
equipment to ensure that this requirement is met. This may require a point-by-point subtraction of the peak jitter vs. time position within an STS line.
