Transmitter Performance Characteristics
Receiver Performance Characteristics
Power supply and grounding: The power supply line should
be well-filtered. All 0.1 µF power supply bypass capacitors
should be as close to the DTR transceiver module as possible.
The two front GND posts (mounting studs) should be
grounded to Chassis Ground for best EMI and ESD protection.
If Chassis Ground is not available, they should be tied to
Circuit Ground.

Wavelength of Operation
Measured average power coupled into single mode fiber (SMF). For 50 µm or 62.5 µm multimode fiber (MMF) operation, the output power is
0.5 dB less and is measured after a single mode fiber offset-launch mode-conditioning patch cord as specified in IEEE 802.3z .

Transmission distance: The transmission distances
indicated for the H3, H5 and H7 modules with DFB laser
options are guidelines only, not guaranteed. The exact
distance is dependent on the particular fiber loss involved
and can be calculated from the optical loss budget.
