FM -16, the multiplexer of 4E1+Ethernet Fiber-optic multiplexer FM -16 ensures transfer and reception of two or four flows E1 (2.048 Mbps) on the optical fiber. The exchange besides data is accomplished on the pair of one-mode optical fibers or on one fiber with multiplexing along the length of wave.

Multiplexer can contain additional Ethernet the channel, connection before which is produced on independent [optovoloknu]. Channel is realized by installation down the basic pay of the multiplexer of the additional charge of [mediakonvertera] MC100-10, with its joints and elements of indication. [Mediakonverter] has the independent description, applied down the instruments in execution OF ETH.

Multiplexers FM -16 are produced before the metal housing by height 1U and are completed by universal corners for the installation beside counter 19” or 21”.

Each channel E1 supports the flow of data of 2.048 Mbps, in accordance with the standard ITU Of g.703. The amplitude and the shape of the pulses of transmitter before the channel E1 correspond to the mask of the pulse of the standard Of g.703 with the work beyond the balanced line (beaten pair) with wave drag to 120 Ohm.

The organs of indication and control, and also the joints of optical channel are located beyond the face side of instrument, and the joints of channels E1 and the joints of nourishment based on the back side. All joints and indicators Of ethernet of channel are arranged on the face side of instrument.

Multiplexer FM -16 can work paired with the multiplexer FM -4 of the corresponding optical performance.

Special features:

• Channels E1 are connected down the multiplexer by the beaten pairs (wave drag 120 Ohm) through the joints DB-9. Each channel through its joint. Multiplexer can be completed additionally by adapters with DB-9 to RJ-45.
• The wavelength of optical interface can be 1310[nm] or 1550[nm] depending on order in execution SM and mm or 1310[nm] and 1550[nm] before each pair in execution SO.
• The multiplexers FM -16 of all performances are produced with the optical connectors SC
• Down the front panel of device are brought out the organs of monitoring and control, and optical connector.

Parameters of the device

The version of the performance of multiplexer is indicated on [stikere] stuck based on the back side of instrument. The structure of designation is given below:

FM16-----<1><2><3><4><5>

<1>- a quantity of channels E1 before as-received condition:

• 2[E]1 - 2 channels;
• 4[E]1 - 4 channels.

Note:
Before the multiplexer FM16-2E1 - the user can establish the modulus of expansion FM2E1 for obtaining the four-channel version of multiplexer.

<2>- ETH - combined multiplexer based on Ethernet as far as [mediakonverterom], is produced only with the single-fiber optical channels of multiplexer and [mediakonvertera]. Before the instruments without [mediakonvertera] the marking before this position is absent.

<3>- the type of optics:

• Mm - pair of [multimodovykh] fibers, wavelength 1310 nm;
• SM - pair of one-mode fibers, wavelength 1310 nm;
• SO - one one-mode fiber with the separation of the entering and outgoing signals along the length of wave (1310/1550 nm).

Note:
1. Optical budget before the standard delivery of instruments is 12 dB at the point of the performances mm, and 19 dB in execution SM and SO. The production of instruments with another wavelength and budget to 40 dB is if necessary possible.
2. The multiplexers of the performance SO work only before the pair CO opposite CE.

<4>- the wavelength of transmitter and receiver for the performance SO:

• CO - transmitter 1550 nm, receiver 1310 nm;
• CE - transmitter 1310 nm, receiver 1550 nm.

<5>- the power source:

• AC - alternating voltage of 100-240[V];
• DC - constant stress of 36-72[V];
• AC+DC - the combined source - the alternating voltage of 90-262[V] and constant stress of 40-80[V].

Overall sizes:

• 195[mm] x of 420[mm] x of 44 mm ([V]x[Sh]x[G])
• Assembly height 1U
• Installation beside counters 19” even 21”
