Additional hidden parameters are all fixed values set at the factory. Parameter Description List of splice modes stored in database is displayed. A selected splice Fiber Type mode stored in the database area is copied to a selected splice mode in the user-programmable area.
Mode Title1 Title for a splice mode expressed in up to nine characters. Detail explanation for a splice mode expressed in up to 15 characters. An error message is displayed if the cleave angle of either the left or right Cleave Limit fiber ends exceeds the selected threshold cleave limit. An error message is displayed if the estimated splice loss exceeds Loss Limit selected threshold loss limit.
Error message is displayed if the cleaved end face of either left or right Cleave Shape Error fiber exceeds the selected threshold cleave shape. Arc Power The Arc Power is changed automatically. This is automatically set depending on the fiber type when AUTO mode is selected. A cleaning arc burns out micro dust on the surface of the fiber with an arc Cleaning Arc discharge for a short period of time.
The duration of the cleaning arc can be changed by this parameter. The duration of this additional arc can be changed by this parameter. SM-SM mode. Below are the descriptions of the various parameters used in these modes. Upon inputting the appropriate mode, the selected splice mode stored in database area is copied to a selected splice mode in user-programmable area. Title for a splice mode expressed in up to seven characters.
Title2 is displayed at the [Splice Mode Select] menu. Sets the aligning method for the fibers. Sets the focal point for fiber observation. The focal point moves closer to the core when [Focus] value is increased.
Left and right fibers are focused independently even if they are a different fiber type dissimilar fiber splicing. If the fiber core cannot be observed e. Sets the axial offset ratio for ECF. See page 70 [ECF Splice] for detail. For a splice mode in which arc time is 5 sec. Optimizes Arc power according to core concentricity-error. This function is used in combination with ECF. An error message is displayed if the estimated splice loss exceeds the Loss Limit selected threshold loss limit.
Fiber Angle An error message is displayed if the bend angle of the two fibers spliced Limit exceeds the selected threshold Fiber Angle Limit. Cleave Error message is displayed if the cleaved end face of either left or right Shape Error fiber exceeds the selected threshold cleave shape. Sets the end-face gap between the left and right fibers at the time of Gap aligning and pre-fusion discharge. Sets the relative position of the splicing location to the center of Gapset electrodes.
Sets the power of the prefuse arc, which is an arc discharge occurring from the beginning until the fibers begin stuffing. If [Prefuse Power] is Prefuse set too low, axial offset may occur if cleaved angles are relatively poor. If Power [Prefuse Power] is set too high, fiber end faces are fused excessively and splice loss gets worse. Sets the duration of the prefuse arc, which is arc discharge occurring from Prefuse Time the beginning until the fibers begin stuffing.
Longer [Prefuse Time] is synonymous with higher [Prefuse Power]. Sets the overlap amount of fibers at the fiber stuffing stage. Relatively Overlap small [Overlap] is recommended if the [Prefuse Power] is low, while relatively large [Overlap] is recommended if the [Prefuse Power] is high.
Arc discharge can be separated into two stages. Arc1 Power is the first Arc1 Power stage. This sets Arc1 Power. Sets Arc1 time. Caution If Arc1Time is set 1 sec. Parameter 66 Splice Menu Description Arc2 is the second arc discharge stage. This sets Arc2 Power. Sets the total Arc2 time.
It is possible to set a very long arc time. A continuous arc over 30 seconds, without weakening the arc power, may damage the arc discharge unit. Arc2 During Arc2 discharge, arc power can be pulsed by turning the arc on and On-Time off. This sets the amount of time that Arc2 is ON. When the Arc2 discharge is Arc2 intermittent, re-arc discharge is also intermittent. Sets Rearc Time.
In other splice modes, the Re-arc power is Rearc Time automatically fixed to the same arc power of [Arc2 Power]. Splice loss is sometimes improved when the fiber is tapered pulled Taper Splice during arc discharge to make the splice thinner.
This sets taper function "ON". The following three parameters determine the taper shape. Sets the taper wait time from the end of fiber stuffing until the start of Taper Wait pulling fiber.
Taper Speed Sets the fiber pulling speed. Taper Length Sets the fiber pulling length. MFD-Right This amount is added to the estimated splice loss originally calculated. When splicing specialty or dissimilar fibers, a high actual splice loss may Minimum occur even with optimized arc conditions. To make the actual splice loss Loss concur with the estimated splice loss, set the minimum value of estimate to the minimum optimized actual splice loss. If Est. These are advanced Mismatch splicer functions and should be discussed with your Fujikura representative before changing.
Parameter Arc2 Power 67 Splice Menu If an incorrect character is CAPS inputted, move the cursor to [BS] and press Enter Characters key to highlight the character, and then input the proper character over it. In the case of Password input, the next screen image is displayed if the correct password is inputted. Manual Splice Mode This mode is to manually align and splice fibers. The following procedure is required, and is different from standard automatic splicing. The fibers stop moving forward at the Gapset position.
The name of the motor to be moved is displayed in the monitor. Motor speed can be selected "fast" or "slow" by pressing Enter key. Press the opposite arrow key to move the motor again.
The message can be displayed by pressing Menu key again. Lens moves away from fiber. ECF Splice When fibers having some core concentricity-error are aligned using the core-to-core method, their outer claddings are not aligned in line with each other as shown below.
However, surface tension created during arc discharge aligns the fibers cladding-to-cladding due to the viscous self-centering effect. This results in a high splice loss due to the fact that the cores of the fibers are offset during the process.
The amount of offset expected due to this surface tension phenomenon is calculated in advance, and this is taken into account to determine an intentional core axis offset amount that is added after the fiber cores are aligned. With this function, the fibers are core-to-core spliced even with the effect mentioned above. A long arc discharge counteracts ECF, because surface tension eventually aligns and splices fibers cladding-to-cladding.
Attenuation splice mode Attenuation splice mode makes an intentional core axial offset to create attenuation at the splice point. Two types of attenuation splice modes are included in the splicer as stated below. A power meter is recommended for correct splice loss measurements. This is often more practical than "Target loss" or "MFD" in terms of accuracy.
Other Refer to other splice modes for complete description. Parameters [AT2] mode This mode allows the users to set a starting core offset value and a finishing core offset value. Set [Start Offset] manually and then splicing starts. A splice loss estimate is not performed. Re-arc is continuously performed until axial offset reaches specific offset amount [Stop Offset].
Axial offset amount Stop Offset decreases as splicing occurs, so [Stop Offset] must always be smaller than [Start Offset]. To decrease variation, set the [Cleave Limit] as low as possible. Cladding alignment is performed with [AT2 MM ] mode.
Splice Option Common parameters for all the modes for splicing and tube heating can be set. Cleave angles are displayed during the pause. Fibers should be prepared and placed into the splicer in advance. Splice Memory This splicer stores up to 2, splicing results.
