The major difference is oven’s maximum temperature capability. Standard epoxy connector oven has a maximum temperature of 150 degrees C, and there are different blocks available which will fit each connector style. The oven block feature built in stops to allow the connector to sit in the center of the oven without passing through to the bottom and breaking fiber stubs. Standard epoxy oven cannot do the Hot Melt connectors. 3M Hot Melt connectors require a temperature of 260 degrees C. Fiber Optics For Sale offers hot melt ovens in 6, 12, and 14 port versions.

In general, there are two main differences between singlemode and multimode connectors. The first and most obvious would be the color of the strain relief boot. A singlemode boot is generally blue or white, while multimode boots are normally black or beige. But, the main difference is in the ferrule of the connector. Singlemode connectors will almost always have a zironia (ceramic) ferrule while multimode connectors can have stainless steel (Nickel-Silver), composite (plasitc), or zirconia. The size of the hole in the center of the ferrule will determine the correct fiber type that the connector is designed for. A standard

126um is the recommended ferrule hole size for 125um singlemode fiber. There are some 125.5um ferrules available for critical alignement situations, but for general connectorization, the 126um hole allows for some epoxy bond around the fiber, and for ease of fiber insertion without breakage. You can choose from a range of connector products on the Connector and Mating Sleeves page.
