Product Description
The EOLS-BI1X12-X series is small form factor pluggable module for Gigabit Ethernet
1000BASE-BX and Fiber Channel single fiber applications by using 1310nm / 1550nm transmitter
and 1550nm / 1310nm receiver. It is with the SFP 20-pin connector to allow hot plug capability.
The transmitter section uses a class 1 laser compliant according to International Safety Standard
IEC 60825. The receiver section uses an integrated B type / A type detector preamplifier (IDP)
mounted in an optical header and a limiting post-amplifier IC.
The EOLS-BI1X12-XD series are designed to be compliant with SFF-8472 Multi-source Agreement
(MSA).
