China Suppliers Factory for Multimode MM MT-MT 40G/100G Transceiver QSFP/SFP+ with Low Loss and Fiber Tolerance
Product Introduction: MT-MT
MT-MT is a type of optical fiber jumper that uses MT (Mechanical Transfer) connectors at both ends. It is primarily employed in optical modules with parallel optical technology, such as QSFP modules, to connect internal optical lenses with external ports, meeting the signal transmission requirements of optical modules. Its main function is to enable high-density, low-loss parallel optical signal transmission, ensuring the stable operation of optical communication systems.
Design and Structure
Connector Type
The MT connector is a high-precision connector with a rectangular cross-section. It has multiple V-grooves inside to fix optical fibers, ensuring precise alignment. The MT-MT jumper uses two MT connectors, which can be male-female or male-male combinations according to requirements.
Fiber Type
Supports various fiber types, including multimode fibers such as OM2, OM3, OM4, OM5, and single-mode fibers such as OS1 and OS2.
Length & Tolerance
The length of the MT-MT jumper is precisely controlled, usually within a range of 20-50 mm, with a length tolerance of ±0.15 mm, to meet the space limitations inside optical modules.
Performance Characteristics
Insertion Loss
Relatively low insertion loss. For multimode fibers, the typical insertion loss is 0.2 dB, and the maximum is 0.60 dB. For single-mode fibers, the insertion loss is usually ≤0.5 dB.
Return Loss
The return loss of multimode MT-MT jumpers is generally >20 dB (flat polish), and that of single-mode MT-MT jumpers can reach ≥55 dB.
Mechanical Stability
Capable of withstanding up to 200 insertions and extractions without significant performance degradation. Operating temperature range is -40°C to +85°C.
Applications & Transmission Rates
MT-MT jumpers are widely used in various types of parallel transmission optical transceiver modules. They play an important role in high-speed optical communication networks, data centers, and other fields, supporting diverse data transmission rates.

Frequently Asked Questions
What is an MT-MT fiber jumper and its primary function? ▼
An MT-MT jumper is an optical fiber cable with MT (Mechanical Transfer) connectors at both ends. It is designed for parallel optical transceiver modules (like QSFP) to connect internal optical lenses with external ports, enabling high-density, low-loss parallel optical signal transmission.
Which fiber types are compatible with MT-MT jumpers? ▼
MT-MT jumpers support both multimode fibers (including OM2, OM3, OM4, and OM5) and single-mode fibers (such as OS1 and OS2) depending on the transmission requirements.
What are the insertion loss and return loss specifications for MT-MT? ▼
For multimode fibers, the typical insertion loss is 0.2 dB (max 0.60 dB) with a return loss of >20 dB. For single-mode fibers, the insertion loss is usually ≤0.5 dB with a return loss of ≥55 dB.
What is the typical length and tolerance of an MT-MT jumper? ▼
The length is precisely controlled to fit inside compact optical modules, usually ranging between 20 mm and 50 mm, with a strict length tolerance of ±0.15 mm.
How durable are MT-MT jumpers under environmental and mechanical stress? ▼
MT-MT jumpers offer excellent stability, withstanding up to 200 insertions and extractions without performance degradation. They operate reliably within a temperature range of -40°C to +85°C.
Which transceiver modules and transmission rates support MT-MT? ▼
They are widely used in QSFP, QSFP+, QSFP28, 100G PSM4, QSFP-DD, OSFP, CXP, CFP, and CDFP modules, supporting high-speed data transmission rates from 40G up to 800G.
