Mini Single Window Single Mode Fiber Coupler
The Oplink mini fused single window wideband fiber 1x2 (2x2) couplers provide
accurate optical signal coupling and splitting over wide bandwidth with high
performance and high reliability in miniature or sub-miniature package. These
couplers have excellent uniformity, low excess loss and very low polarization
sensitivity and are available with various tap ratios, wavelength ranges, fiber
types, and connector options. The small form factor with reduced cladding fiber
is essential for compact system integration. All devices are shown to be able to
handle high optical power up to 4W and are tested according to industry stan-
dard procedures. Reliability is guaranteed through stringent tests to fully meet
Telcordia GR-1221 requirements.
Oplink can provide customized designs to meet specialized feature applications. Also,
Oplink offers modular assemblies that integrate other components to form a full
functionmodule or subsystem.

1. Under all states of polarization and within the full operating temperature and wavelength ranges specified, not include contribution
from connectors.
2. Temperature Sensitivity Coefficient ~0.002dB/°C at the range of -5 to 75°C
3. Operating temperature range changes to -5 to 75°C in P2, P3 package and all package with connectors
4. The mechanical tolerance should be +/- 0.2 mm on all package dimensions unless otherwise custom specified.
