FP-1310-10LRM-X
1310NM FP LASER FOR 10GBASE-LRM
NOTES
1.
1. Operating current is the average bias current required
to meet the ER, rise/fall, and bandwidth specifications.
The target operating condition is 35 mA over threshold at
high temperature, 30mA over threshold at RT.
Output power specification must be met into both single-
mode fiber and 62/125 multi-mode fiber.
Encircled flux is measured at the end of a 10m patchcord
through a fiber shaker per IEC 61280-1-4.
TOSA would be capable of meeting other specifications
when modulated over this ER range.
Maximum change in power as fiber is rotated by 360º.
See Figure 1 below for the present 10GBASE-LRM spectral
width vs. wavelength specification, and TOSA requirement
curve that is further restricted to 3 nm for margin, but is
limited by the IEEE curve below 1275nm.

8.
Measured per IEEE 802.3ae specifications.
Measured with an optical receiver with a 10.3125 Gb/s
filter (4th order Bessel-Thomson filter with 3 dB
bandwidth = 0.75*bitrate).
TWDP is measured as defined in IEEE 802.3aq.

2.
10. Laser slope resistance is measured between “Bias+” and
“Bias-“ pins.
11. Tracking error is defined as the coupled power difference
at Tmax or Tmin (relative to 25 C) where the back monitor
current, Imon, is held constant at the value found at 25 C
at I=Iop.
