Duplexer is made up of low pass filter and high pass filter (or band filter) substantially, has the features such as low insertion loss, high-isolation and low reflection, can reduce the debugging efforts of complexity, can simplify circuitry design. Duplexer mixes the signal of low pass port and high pass port, effectively removes the signal beyond passband and the interference of unnecessary frequency range, frequency so that the two-band signal infiltrating user port is unaffected. Duplexer, according to statement custom, is written as X/Y mode duplex device in this specification, X represents low pass filter cutoff frequency, and Y represents High Pass Filter Cutoff Frequency. Such as 30/36 mode duplex device represents that low pass filter cutoff frequency is 30MHz, and High Pass Filter Cutoff Frequency is 36MHz. 65/87 mode duplex device represents that low pass filter cutoff frequency is 65MHz, and High Pass Filter Cutoff Frequency is 87MHz.

In like manner, when user port, 30/36 mode duplex device COM port and 65/87 mode duplex device COM port form a T-shaped topological structure on a printed circuit, 65/87 mode duplex device COM port is the fork circuit of this T-shaped topological structure, and when user port distance 30/36 mode duplex device COM port is close, it is possible to save the inserted sheet 5 in Fig. 2. Because when selecting 65/87 pattern, user port is very short to this section of circuit of 30/36 mode duplex device COM port, and the signaling reflex caused is only small, and this section of line signal integrity impact of user port to 65/87 mode duplex device COM port can be ignored.

When EOC chip port, 30/36 mode duplex device LP port and 65/87 mode duplex device LP port form a T-shaped topological structure on a printed circuit, 30/36 mode duplex device LP port is the fork circuit of this T-shaped topological structure, and when EOC chip port distance 65/87 mode duplex device LP port is close, it is possible to save the inserted sheet 4 in Fig. 2. When user port, 30/36 mode duplex device COM port and 65/87 mode duplex device COM port form a T-shaped topological structure on a printed circuit, 30/36 mode duplex device COM port is the fork circuit of this T-shaped topological structure, and when user port distance 65/87 mode duplex device COM port is close, it is possible to save the inserted sheet 6 in Fig. 2.
This better embodiment also includes the another kind of common version in Fig. 5, also includes and the hardware designs of this form similar structures. This form is directed to following other possible cable TV networks and designs, and increases the duplexer of other patterns according to different situations.
Adopt method described in this better embodiment, compared with prior art, the method using soft and hardware to combine, the upstream band conflict in CMTS network of former EOC equipment can have been evaded simultaneously, inadequate with bandwidth in non-CMTS network, the problem that transfer rate does not reach 300Mbps.
