Specifications

Description

A High Power SC/APC Fixed Attenuator 20 dB is a fiber optic inline device designed to reduce the optical signal strength by exactly 20 dB. It features SC connectors with APC polish (Angled Physical Contact) on both ends, ensuring very low back reflection, making it ideal for sensitive high-performance fiber optic links and systems that require signal attenuation without compromising signal integrity.

Specifications

Connector Type: SC/APC (Angled Physical Contact)
Attenuation: Fixed 20 dB ±0.5 dB
Wavelength: Typically 1310 nm / 1490 nm / 1550 nm
Fiber Type: Singlemode (SM)
Return Loss: = 60 dB (due to APC polish)
Insertion Loss: = 0.7 dB (excluding attenuation)
Power Handling: High power — up to 500 mW or higher (varies by manufacturer)
Operating Temperature: –40°C to +75°C
Storage Temperature: –40°C to +85°C
Ferrule Material: Zirconia ceramic
Housing Material: Stainless steel or metal
Durability (Mating Cycles): = 1000 cycles
RoHS Compliant: Yes

Features

High power handling: Suitable for high power fiber optic transmitters, such as DWDM, CATV, or laser modules.
Low back reflection: SC/APC connectors reduce reflection to = –60 dB, critical for sensitive receivers.
Fixed attenuation: Consistent 20 dB attenuation protects receivers from overpower or adjusts link budget.
Robust build: Metal housing and high-quality zirconia ferrules ensure durability and stable performance.
Wide wavelength support: Covers telecom wavelengths common in singlemode fiber optics.

Ideal Uses

Protecting sensitive receivers from high optical power signals.
Adjusting optical power levels in DWDM, CATV, PON, and high-power laser systems.
Network test labs requiring fixed, reliable 20 dB attenuation.
Ensuring consistent power budgets over optical fiber links.

Why Choose This Product?

SC/APC connector ensures very low reflection, ideal for long-distance and high-speed fiber optic systems.
High power rating supports high output optical transceivers without damage.
Precise fixed attenuation allows predictable link power management.
Durable design suitable for field installation or lab use.
