Overview

The transceiver consists of three sections: a 850nm VCSEL laser transmitter, a PIN photodiode

integrated with a trans-impedance preamplifier (TIA) and MCU control unit. All modules satisfy

class I laser safety requirements.

The transceivers are compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement

(MSA)1. They are compatible with Fiber Channel per FC-PI-2 Rev. 10.0. also simultaneously

compatible with Gigabit Ethernet as specified in IEEE Std 802.3.
