Four optical ports are arranged at the pedestal; a first single-fiber bidirectional transmission optical assembly, a second single-fiber bidirectional transmission optical assembly, a third single-fiber bidirectional transmission optical assembly, and a fourth single-fiber bidirectional transmission optical assembly are arranged inside the pedestal; the first single-fiber bidirectional transmission optical assembly and the second single-fiber bidirectional transmission optical assembly are arranged side by side and are adjacent to the optical ports of the pedestal; and the third single-fiber bidirectional transmission optical assembly and the fourth single-fiber bidirectional transmission optical assembly are arranged side by side and are adjacent to electrical ports of the pedestal. According to the QSFP+ light receiving-transmitting integrated module, a building base band unit (BBU) is arranged and a single-fiber bidirectional transmission optical assembly is arranged inside a remote radio unit (RRU); and one BBU can carry out bidirectional communication with four RRUs simultaneously by four fibers. Therefore, the fiber resources are saved well and thus the network operation and maintenance costs are reduced. Moreover, the transmission distance can be extended to be 10KM and above; and the fiber utilization efficiency is improved obviously.
Description
Technical field
The present invention relates to a kind of optical communication network module, particularly relate to a kind of QSFP+ integrated module of optical transceiver.
Background technology
Current optical communication network uses distribution-type base station architecture in a large number, needs to connect with optical fiber between indoor baseband processing unit (BuildingBasebandUnit, hereinafter referred to as BBU) and far-end RF module (RemoteRadioUnit, hereinafter referred to as RRU).For down direction: optical fiber is attached directly to RRU from the BBU of base station, between BBU and RRU, transmission is baseband digital signal, such base station can control the signal of certain user and go out from the RRU channel emission specified, it is possible to be substantially reduced the interference to these other Channels user of community.For up direction: user mobile phone signal is received by closest passage, then pass to base station from this passage through optical fiber, so can also be substantially reduced on different passage the interference between user.Between each BBU relatively independent, owing to the transmission range between BBU and RRU is most within 1.4KM, 3 and 1 double, two fiber-optic transfer integrated modules of optical transceiver are each included in existing each BBU unit and RRU unit, and the optical module in every corresponding RRU unit of double, two fiber-optic transfer integrated modules of optical transceiver in BBU unit, namely, one BBU is by 6 optical fiber and three RRU communications, but three RRU of connection corresponding to each BBU can in different communities, so, can cause that the number of fibers between BBU and RRU is many, complicated across cell layout, especially sunken cord limited amount, operation cost is high to cause optical-fiber network to safeguard.
Summary of the invention
For overcoming disadvantage mentioned above, the present invention provides the QSFP+ integrated module of optical transceiver that a kind of network operation cost is low.
For reaching above goal of the invention, the present invention provides a kind of QSFP+ integrated module of optical transceiver, including: a base, this base is provided with four optical ports, being provided with in it: first, second, third, fourth single fiber bi-directional transmission optical assembly, described first, second single fiber bi-directional transmission optical assembly is placed side by side and adjacent with described base optical port；Described three, the 4th single fiber bi-directional transmission optical assemblies are placed side by side and adjacent with described base electrical interface.
Described first, second single fiber bi-directional transmission optical assembly is plug-in optical interface, the three, the 4th single fiber bi-directional transmission optical assembly band tail optical fibers.
Described first and second, the three, the 4th single fiber bi-directional transmission optical assembly band tail optical fibers.
The QSFP+ integrated module of optical transceiver due to said structure, owing to being just equipped with first in only one encapsulation base plate, second, third and fourth single fiber bi-directional transmission optical assembly, there are four optical ports, this QSFP+ integrated module of optical transceiver is set to a BBU unit, a single fiber bi-directional transmission optical assembly it is also provided with in RRU unit, so, one BBU unit just can with four RRU unit simultaneous bi-directional communications by four optical fiber, save fiber resource well, thus reducing operation and the maintenance cost of network, and transmission range can extend to 10KM and more than, the utilization ratio of optical fiber can significantly improve.
