Product Description The EOLF series multi-mode transceivers is small form factor, low power, high performance module for bi-directional serial optical data communications such as Gigabit Ethernet IEEE 802.3z 1000BASE-SX, SONET/SDH and Fiber Channel 2X/1X. This module is designed for multi-mode fiber and operates at a nominal wavelength of 850nm. The transmitter section uses a multiple quantum well 850nm VCSEL and is a class 1 laser compliant according to International Safety Standard IEC The receiver section uses an integrated GaAs detector preamplifier (IDP) mounted in an optical header and a limiting post-amplifier IC. A LVTTL logic interface simplifies interface to external circuitry. Interface information The Signal Detect (SD, active high), normal optical input of receiver represents to a logic 1 level, which means asserted. The following versions are available: 1. AC/AC Transceiver Tx and Rx are AC coupling. Tx has differential 100Ω load. 2. DC/DC Transceiver Standard PECL inputs and outputs, Tx and Rx are DC coupling. 3. AC/DC Transceiver Tx is AC coupled, Differential 100Ω load, Rx has standard PECL output and is DC coupling. Page 2 of 9
