MR-J3BUS Mitsubishi Servo Fiber Optic Cable Assembly
The MR-J3BUS Mitsubishi Servo Fiber Optic Cable Assembly is a duplex servo lead with MR-J3BUS-style connectors and length-coded variants, used for MR-J3 servo optical communication, automation equipment maintenance, and length-specific spare inventory.
Product Overview
Designed for MR-J3 servo optical communication and replacement cable inventory, this assembly pairs MR-J3BUS-style duplex servo connectors with black industrial cable offered in model-specific length variants. The image set includes multiple length-coded labels. Visible housing/jacket/color/ferrule/protection options are confirmed in the quotation or approved drawing.
Key Features
- MR-J3BUS-style duplex servo connectors
- Black industrial cable in model-specific length variants
- Passive optical path with no conductive connection
- Length, jacket, labeling, and routing protection configurable
- Length-coded labels (e.g. MR-J3BUS015M/05M/10M-A/25M-A)
- Suited to servo drive installation and production-line repair

Performance & Reliability
Optical performance depends on fiber selection, termination quality, end-face cleanliness, bend control, finished length, and correct seating. The passive path gives EMI immunity; the paired servo transmitter and receiver define the link. Because the image set includes multiple length-coded labels, confirm the suffix, length, bend routing, and connector orientation before purchase.
Customization & Ordering
We supply MR-J3BUS assemblies in the required length suffix, with configurable jacket, labeling, and protection. Confirm the servo drive and required length. Compare with the G396/G380 cable and the FANUC external cable. Quote: sales@fevelectronics.com.
FAQ
Q: Which MR-J3BUS length suffix do I order?
A: Match the suffix (e.g. MR-J3BUS015M, 05M, 10M-A, 25M-A) to the required servo-to-drive distance; confirm length, bend routing, and connector orientation.
Q: Is this the same as J3BUS?
A: It is the MR-J3-length-coded variant of the J3BUS servo optical bus; see the J3BUS cable.
Q: Can it be used on FANUC servos?
A: Only if the connector matches; see the A66L-6001-0026 for FANUC.
