Introduction

OLYCOM's OSBL1G20D-53 Transceivers are an unbeatable combination of high-performance functionality and affordability. With a single LC optics interface, they are fully compliant with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA).
Their digital diagnostics capabilities are easily accessible via the 2-wire serial bus as specified in SFF-8472.
The receiver section is designed with a PIN receiver, while the transmitter utilizes a 1550 nm DFB laser.
With a remarkable up to 14dB link budget, this module excels at 1000Base-LX Ethernet 20km applications without fail.
