Knowledge Base + 2024.01.16

10G SFP+ BIDI series optical modules include 10G SFP+ BIDI 10km, 10G SFP+ BIDI 20km, 10G SFP+ BIDI 40km, 10G SFP+ BIDI 60km, 10G SFP+ BIDI 80km and so on, which are available in commercial grade temperature, extended grade temperature and industrial grade temperature. They are available in commercial-grade, extended-grade, and industrial-grade temperatures for customers to choose from.

10G SFP+ BIDI adopts LC optical port and is compatible with IEEE802.3ae and SFF-8472 standards, featuring low power consumption, small size and high speed. It is mainly used in data center interconnection, SONET/SDH, metro network, 4G LET wireless network, transmission network, high-speed point-to-point link, Fibre Channel and other environments. 10G SFP+ BIDI optical module can be adapted to Huawei, Huasan, Cisco, Alcatel-Lucent, Juniper, HP and other equipment.

Features and advantages of BIDI optical module:

1. General optical modules have two ports, such as TX transmitter port and RX receiver port, while BIDI optical modules have only one port, BIDI optical modules can simultaneously complete the transmission and reception of optical signals. Therefore, BIDI modules must be used in pairs. 

2. The biggest advantage of the BIDI optical module is to save fiber resources, allowing two transmission fibers to be combined into one. the BiDi optical module reduces the cost of fiber optic cabling infrastructure and the number of ports on the fiber optic patch panel, as well as reduces the amount of space taken up by trays dedicated to fiber optic management.

SFP+ BIDI single-fiber bi-directional 10Gbps optical modules support 10G transmission rates, with low-jitter, high-performance 1330nm/1270nm DFB laser components (1330/1270nm wavelengths) in the transmitter section to support a maximum transmission distance of 10km. hot-swappable, single-fiber bi-directional transmission with digital diagnostic monitoring, and support for commercial-grade temperature ranges (0℃~+70℃). 70℃). Mainly used in 10GBASE LR Ethernet Ethernet, 10G LW Fibre Channel, etc. BiDi (Bidirectional), i.e., single-fiber bidirectional. BiDi (Bidirectional) is a single-fiber bi-directional fiber that uses WDM technology to transmit and receive optical signals in two directions using different center wavelengths.

To achieve a single optical fiber bi-directional transmission of optical signals. General optical module has two ports, TX for the transmitter port, RX for the receiver port; while the optical module has only one port, through the filter in the optical module for filtering, and at the same time to complete the 1270nm optical signal transmission and 1330nm optical signal reception, or vice versa. Therefore, the module must be used in pairs, his biggest advantage is to save fiber resources.
