We provide WDM couplers or multiplexers for special wavelengths. These optical couplers are manufactured using fused fiber technique. They combine and split signals at 1064nm and 1550nm, or 1550nm and 1625nm, with low insertion loss, polarization insensitive, high reliability and high isolation. Other available wavelengths include 980/1310nm, 1064/1310nm WDM couplers.
Multimode optical fiber couplers are widely used in optical local networks or FTTx networks that use multimode fibers. These couplers can be fabricated using 50/125 or 62.5/125 micron fibers and at central wavelengths of 850nm or 1310n.
Single mode wideband couplers have 80nm bandwidth, compared to 40nm of standard single mode couplers. This product has very low excess loss and high temperature stability.
