For your product safety, please read the following information carefully before any manipulation of the transceiver:
ESD
This transceiver is specified as ESD threshold 1kV for SFI pins and 2kV for all others electrical input pins, tested per MIL-STD-883G, Method 3015.4
/JESD22-A114-A (HBM). However, normal ESD precautions are still required during the handling of this module.
LASER SAFETY
This is a Class1 Laser Product according to IEC 60825-1:2007. This product complies with 21 CFR 1040.10 and 1040.11 except for deviations
pursuant to Laser Notice No. 50, dated (June 24, 2007).
The optical ports of the module need to be terminated with an optical connector or with a dust plug in order to avoid contamination.
1.
Overview
SFP85P55GExx is a high performance transceiver module for Gigabit Ethernet data links over a multimode fibre pair.
The maximum reach1 is 550m (50/125µm), with 7.5dB end of life (EOL) power budget. The emitter is an 850nm VCSEL
laser, the receiver is a PIN photodiode.
This transceiver module is compliant with the Small Form-factor Pluggable (SFP) Multisource Agreement (MSA) and hot
pluggable. Always contact Skylane Optics commercial agents for compatibility with different equipment platforms.

Distance is estimated assuming typical optical losses after decent quality fibre deployment; Only optical budget value is guaranteed.
EOL, over operating temperature range
Measured with 1.25Gbps PRBS 27-1, ER=9dB, BER≤10-12
The optical input to the receiver should not exceed this value. Transmitters must never be directly connected to receivers (optical loop back) before ensuring that
proper optical attenuation is used.
