They are usually used to connect a remote RF cabinet.
The optical fiber jumpers connect the blind match connectors of the BDS backplane
RIM0 master/slave slots to the optical adaptors on the two BIM6 interface boards. The
jumpers are available with the following types: MTP4-LC-0.5M, BMTP8-LC-0.5M
and BMTP12-LC-0.5M, and the optical fibers are connected in the spectrum order of
blue, orange, green, brown, gray, white, red, black, yellow, purple, pink and cyan.
When installing optical fibers, make sure that the bending radius is larger than 40 mm
to prevent any damages. In addition, the optical fibers should not be bundled too tight
and there should be some space kept between an optical fiber and the clips.
7.2.4 Installing Monitoring Cables in the BDS
The internal monitoring cables of the BDS include cables for front access control
monitoring, CCM board temperature monitoring, CHM board temperature monitoring,
flooding monitoring and fan monitoring.
The internal monitoring cables adopt the one-to-eight structure with the ends being A
and B1 ~ B8. End A is connected to the X154EMSOCKET socket on the BDS
backplane; B1 is connected to the front door position switch along the right side of the
chassis; B2 is designed to be connected to the back door position switch (now idle); B3,
B4 and B5 are temperature sensors connected to the top of the CCM and CHM boards;
B6 is connected to the DB25 socket of the fan plug-in box backplane; B7 is to the
lightning-proof board of the BDS filter; B8 is to the flooding sensor (unnecessary when
the BDS is mounted on the RFS cabinet) at the lower right corner of the BDS.
