Optiva OTS-2O Series Micro Erbium Doped Fiber Amplifiers (µEDFA)

The EMCORE OTS-2O Series µEDFA and OTS-2OP µEDFA preamplifier are designed to meet the most demanding noise performance requirements of fiber optic communications and control systems and perform all the functions required of an optical amplifier and pre-amplifier for system integration.

The OTS-2O µEDFA and OTS-2OP µEDFA preamplifier modules provide input and output optical isolation for stable, low-noise operation. The input and output optical signal power levels are detected for monitoring and control. The input optical signal is amplified with active gain control for a constant output power level, or with active output power control for constant gain mode operation. In the OTS-2OP preamplifier the very low level input optical signal is initially pre-amplified, then amplified with active output power control for constant power mode operation.

The OTS-2O and OTS-2OP series also provide local and remote monitors and alarms for all critical operating parameters via SNMP and EMCORE View GUI. The optical output can be split into multiple ports by optional external splitter. An optional back reflection monitoring feature enables safe output optical power management.

A consultation with your EMCORE representative, or authorized EMCORE reseller is the 1st step in designing your system. Email Us, or call 626-293-3400, Ext. 3501 for a design consultation.
