MXn-Serie

Small & Compact Multi-channel FORJ for Tight Spaces

A very compact package accommodates 2-3 channels and 4-7 channels (SM or MM fibers). It’s mounting scheme is similar to RJ2 series FORJs making it simple to upgrade from MM RJ2 to SM MX2. MXn series FORJs feature “blind-spot free” passage and low crosstalk.

MXn-FORJ Series

Multi Channel Fiber Optical Rotary Joint

MXn series multi-pass Fiberoptic Rotary Joints (FORJs) are compact multi-channel products. They connect 2-3 (Model MXnS) or 2-7 (Model MXn and MXnL) independent fiber channels simultaneously. They are ideal when combined with electrical slip rings or RF rotary joints or when space is tight in general.

Though very small they still feature standard optical performance (<-60 dB crosstalk, <5 dB insertion loss, and >45 dB return loss). All channels can accommodate either singlemode or multimode fibers. It is also possible to combine the two types of fibers in one device. Choose the MXnL model if IP 65 rating is required.

Note: All insertion loss and return loss measurements are performed by joining the FORJ to the light source through a fusion splice (without the use of connectors). Insertion loss of all receptacle types of FORJs, such as RST, RFC, and RFCX, are measured with connectors of similar type. Their return loss is not measured.
