Product information

Description

The Optical attenuator CBO SFA21BK11 — Singlemode LC Simplex 11 dB is a passive inline device for singlemode fibre networks that reduces optical power by 11 dB. It features an LC simplex connector and a compact housing designed for patch panels, racks or field cabling. The unit is plug-and-play and requires no configuration, providing a straightforward way to match transmitter output to receiver sensitivity or to protect sensitive optical components during installation and testing.

Advantages

The attenuator offers precise, repeatable attenuation in a compact format suitable for dense installations. Its singlemode design preserves signal quality while lowering power to prevent receiver overload. The LC simplex interface ensures broad compatibility with standard singlemode transceivers and patch cords. The passive construction means no power or maintenance is required, and the inline form factor allows quick insertion into existing links without modifying active equipment.

Suitable for

  • Power level adjustment between singlemode optical transmitters and receivers
  • Field testing and link commissioning where controlled attenuation is required
  • Protecting optical receivers and transceivers from excessive input power
  • Temporary insertion during maintenance or troubleshooting of fibre links

Key specifications

  • Fibre type: Singlemode
  • Connector type: LC simplex
  • Nominal attenuation: 11 dB
  • Form factor: Inline/passive attenuator
  • Operating principle: Fixed passive optical attenuation

How to use

Insert the LC simplex connector of the attenuator between the transmitter or patch cord and the receiver or fibre patch panel port. Ensure connectors and fibre endfaces are clean before mating to avoid additional loss or damage. The device is directional in some installations; verify signal direction if link performance is unexpected. No electrical power or configuration is required — once connected, the attenuator immediately reduces optical power by the specified value.

Usage recommendations

For reliable operation, inspect and clean fibre endfaces before use, avoid bending the fibre beyond recommended radii near the attenuator, and store unused units with dust caps fitted. When precise power levels are critical, verify link power with an optical power meter after insertion and choose the correct attenuation value to match receiver sensitivity.

Оптический аттенюатор CBO SFA21BK11 — Singlemode LC Simplex 11 dB представляет собой пассивное inline-устройство для одномодовых оптических сетей, снижающее оптическую мощность на 11 дБ. Аттенюатор оснащён разъёмом LC simplex в компактном корпусе, подходящем для установки в патч-панели, стойки или для полевых работ. Устройство не требует настройки и обеспечивает простой способ согласования выходной мощности передатчика с чувствительностью приёмника или защиты активных компонентов при вводе в эксплуатацию и тестировании.

Преимущества

Аттенюатор обеспечивает точное и воспроизводимое ослабление в компактном исполнении, удобном для плотной установки. Одномодовая конструкция сохраняет качество сигнала при снижении мощности, предотвращая перегрузку приёмника. Интерфейс LC simplex обеспечивает совместимость со стандартными одномодовыми трансиверами и патч-кордами. Пассивная конструкция не требует питания и обслуживания, а inline-формат позволяет быстро подключить устройство в существующие линии без вмешательства в активное оборудование.

Подходит для

  • Регулировки уровней мощности между одномодовыми передатчиками и приёмниками
  • Полевых испытаний и ввода линий в эксплуатацию с контролируемым ослаблением
  • Защиты оптических приёмников и трансиверов от избыточной входной мощности
  • Временной вставки при обслуживании или диагностике оптических линий

Ключевые характеристики

  • Тип волокна: одномодовое
  • Тип разъёма: LC simplex
  • Номинальное ослабление: 11 дБ
  • Форм-фактор: inline / пассивный аттенюатор
  • Принцип работы: фиксированное пассивное оптическое ослабление

Как использовать

Вставьте разъём LC simplex аттенюатора между передатчиком или патч-кордом и приёмником либо портом патч-панели. Перед соединением убедитесь в чистоте разъёмов и торцов волокна, чтобы избежать дополнительного затухания или повреждений. В некоторых случаях устройство может быть направленным, поэтому при ненормальной работе проверьте направление сигнала. Аттенюатор не требует питания или настройки — после подключения он сразу уменьшит оптическую мощность на заданное значение.

Рекомендации по использованию

Для надёжной работы осматривайте и очищайте торцы волокон перед использованием, избегайте сильных изгибов волокна рядом с аттенюатором и храните неиспользуемые изделия с заглушками. При необходимости точной установки уровней мощности контролируйте значения оптическим ваттметром после вставки и выбирайте подходящее ослабление для соответствия чувствительности приёмника.

Optiskais slāpētājs CBO SFA21BK11 — Singlemode LC Simplex 11 dB ir pasīvs inline ierīce viendabīga optiskā tīkla vajadzībām, kas samazina optisko jaudu par 11 dB. Ierīcei ir LC simplex savienotājs un kompaktā korpusa konstrukcija, kas piemērota izvietošanai patch panelēs, skapjos vai lauka darbos. Ierīce ir plug-and-play un neprasa konfigurēšanu, nodrošinot vienkāršu veidu, kā pielāgot raidītāja jaudu pie uztvērēja jutības vai aizsargāt aktīvos komponentus testēšanas laikā.

Priekšrocības

Slāpētājs nodrošina precīzu un atkārtojamu slāpējumu kompakta izmēra izpildījumā, kas piemērots blīvām instalācijām. Viendabīga konstrukcija saglabā signāla kvalitāti vienlaikus samazinot jaudu, tādējādi novēršot uztvērēja pārslogošanu. LC simplex saskarne nodrošina plašu savietojamību ar standarta viendabīgiem transīveriem un patch vadiem. Pasīvā konstrukcija nozīmē, ka nav nepieciešams barošanas avots vai apkope, un inline forma ļauj ātri ievietot ierīci esošos savienojumos bez iejaukšanās aktīvajā aprīkojumā.

Piemērots

  • Jaudas līmeņa regulēšanai starp viendabīgiem optiskajiem raidītājiem un uztvērējiem
  • Lauka testēšanai un savienojumu nodošanai ekspluatācijā ar kontrolētu slāpējumu
  • Optisko uztvērēju un transīveru aizsardzībai pret pārmērīgu ieejas jaudu
  • Pagaidu ievietošanai uzturēšanas vai problēmu novēršanas laikā optiskajos savienojumos

Atslēgas specifikācijas

  • Vīķa veids: viendabīgs (singlemode)
  • Savienotāja tips: LC simplex
  • Norādītais slāpējums: 11 dB
  • Formfaktors: inline / pasīvs slāpētājs
  • Darbības princips: fiksēts pasīvs optiskais slāpējums

Kā lietot

Ievietojiet LC simplex savienotāju starp raidītāju vai patch vadu un uztvērēju vai patch paneles portu. Pirms savienojuma izveides pārbaudiet un notīriet savienotājus un šķiedras gala virsmas, lai izvairītos no papildu zudumiem vai bojājumiem. Ja nepieciešams, pārbaudiet signāla virzienu, ja saites veiktspēja neatbilst gaidītajai. Ierīce neprasa barošanu vai konfigurāciju — pēc pievienošanas tā nekavējoties samazina optisko jaudu norādītajā apmērā.

Izmantošanas ieteikumi

Lai nodrošinātu drošu darbību, pirms lietošanas pārbaudiet un notīriet šķiedru gala virsmas, izvairieties no stipriem līkumiem šķiedrā pie slāpētāja un uzglabājiet neizmantotas ierīces ar putekļu vāciņiem. Precīziem jaudas līmeņiem izmantojiet optisko jaudas mērītāju pēc ievietošanas un izvēlieties atbilstošu slāpējuma vērtību, lai atbilstu uztvērēja jutībai.
