PC Board Mount Dual-Transmitter
100 Mbps – 5 Gbps, MMF, 3.3V
Required Host Board Components
A power supply noise rejection filter as describe in SFP MSA is required on the host PCB to meet data sheet
performance. This filter incorporates an inductor which should be rated 400 mADC and 1 Ω series resistance or better. It
should not be replaced with a ferrite. The required filter is illustrated in Figure 4. Also, the host PCB for the board mount
dual-transmitter requires 4.7 K to 10 KΩ pull-up resistors for TX1_FAULT, TX2_FAULT, SCA and SDL lines.

Fiber Compatibility
The dual-transmitter is capable of transmission at 2 to 550 meters with 50/125 μm fiber, and at 2 to 275 meters with 62.5
125 μm fiber, for 1.25 GBd Ethernet. It is capable of transmission up to 550m with 50/125 μm fiber and up to 300m with
62.5/125 μm fiber, for 1.0625 GBd Fiber Channel.
Electrostatic Discharge (ESD)
The Dual-transmitter is compatible with ESD levels found in typical manufacturing and operating environments as
described JEDEC EIA JESD22-A114-A, Class 1 (<2000Volts) HBM. Glenair recommends that devices are handled with
ESD precautions to limit exposure to below 500V HBM.
There are two design cases in which immunity to ESD damage is important. The first case is during handling of the dual-
transmitter prior to insertion to the host board. To protect the dual-transmitter, it’s important to use standard industry ESD
handling precautions. These precautions include using grounded wrist straps, work benches, and floor mats in ESD
controlled areas. The ESD sensitivity of the Glenair board mount dual-transmitter is compatible with typical industry
production environments.
The second case to consider is static discharges to the exterior of the host equipment after installation, in which case the
dual-transmitter may be subject to system-level ESD requirements.
