匹配套管
我们的匹配套管能够连接终端为行业标准FC/PC、FC/APC、SMA、LC®/PC、SC/PC和ST®*/PC®接头的光纤跳线。除了我们具有空气间隙的SMA匹配套管，我们其他的匹配套管能够准确对准每根带接头光纤的纤芯，使光纤直接接触将背向反射降至最小。Thorlabs在本页还提供一些预装在L形支架上的匹配套管，兼容标准的1/4"-20(M6)光机械元件。
插口转接件
Thorlabs的FC/PC、SMA和ST/PC插口转接件(ST/PC插口转接件也可以按1包10个购买)含有一个用于将光投射到自由空间的接头。它们的结构紧凑，具有安装螺纹，非常适合OEM或自搭建的应用。FC/PC和SMA插口转接件采用一体式设计，易于集成到自搭建的应用中；用于ST/PC插口转接件的3/8"-24锁定螺母单独出售，适合OEM应用。这些转接件的设计使接头插芯的前端面与转接件后表面对齐。这样可以使光纤几乎直接接触转接件后的任何光学元件或仪器。
保养和正确的使用方法
光纤端面保持清洁很重要，这样可以尽可能地减少连接损耗，并且避免损坏接头。除了我们的SMA匹配套管，光纤头在我们所有的匹配套管中直接接触。使用我们的G608N3折射率匹配凝胶(下方出售)也有助于减少光纤连接处的损耗。Thorlabs提供了全面的光纤检测工具和光纤清洁用品。对于有接头的光纤，我们可重复使用的光纤对光纤连接产品能够建立临时连接。我们还提供光纤防尘帽用于保护光纤的端面。

(posted 2023-04-13 10:48:10.0) Thank you for reaching out to us with this inquiry. The body of this component is indeed stainless steel, and the sleeve inside is ceramic. user
(posted 2023-03-09 08:43:15.783) Hi, is the ADAFCPM2 supposed to have some play in the inner-most sleeve (where the ceramic is)? Is it supposed to be able to move relative to the square flange when a fiber is screwed to one side?
Thanks jgreschler
(posted 2023-03-10 02:37:58.0) Thank you for reaching out to Thorlabs. There are a couple of reasons this might be happening, the most likely is that the ceramic split sleeve inside the metal housing is cracked. I've reached out to you directly to troubleshoot this and resolve the concern. Dahlia Ghoshal
(posted 2023-02-21 14:34:13.563) Hi, I was wondering why there are mating sleeve options for both wide and narrow key slots? If all Thorlabs fiber patch cables have narrow keys, is there a situation in which a wide key slot is preferable? jgreschler
(posted 2023-02-24 10:54:09.0) Thank you for reaching out to Thorlabs. Generally speaking, if the fiber type doesn't require rotational accuracy like multimode or single mode, there is no issue with using a wide key mating sleeve for a narrow key connector. This is not the case for polarization maintaining fibers which require the axis rotation to be accurate, so we would recommend using narrow key mating sleeves for that application. Shuyu Dong
(posted 2022-11-15 14:43:17.457) Dear Officer,
May I know the fabrication tolerance of ADAF1? Such as the tolerance of the inner circle diameter, the outer circle diameter, and the width of the opening gap.

(posted 2022-04-29 18:02:32.787) Is it okay to connect an FC/PC patch cable at one end of this mating sleeve (ADAFC3) and FC/APC cable at the other end? Will there be any losses? jgreschler
(posted 2022-05-03 10:43:14.0) Thank you for reaching out to Thorlabs. ADAFC3 is not suitable for mating an FC/PC to an FC/APC connector, there will be an air gap between the fibers due to the angle in FC/APC. Michael Debus
(posted 2022-04-21 08:46:24.973) Hi,
I have a question regarding the ADAFCSMA1. The description reads "SMA mating sleeves are air spaced". Does this also hold for the FC-PC to SMA adapter or are the two fibers in direct contact when using the ADAFCSMA1 mating sleeve?
Kind regards,
Michael jgreschler
(posted 2022-04-21 10:20:25.0) Thank you for reaching out to Thorlabs. The FC/PC to SMA mating sleeve does leave an air gap between the two ferrules. Viktor Erlandsson

(posted 2021-08-24 13:22:24.077) Hi, what improvements can be expected when using the index matching gel with a APC/APC PM fiber mating? Thanks! YLohia
(posted 2021-08-30 11:28:11.0) Hello, thank you for contacting Thorlabs. Index-matching gels may be used in conjunction with pairs of mated connectors or with mechanical splices to reduce signal reflected in the guided mode (optical return loss). Without the use of an index-matching material, Fresnel reflections will occur at the smooth end faces of a fiber unless there is no fiber-air interface or other significant mismatch in refractive index. These reflections may be as high as −14 dB. Unfortunately, we don't have a spec for the improvements for APC-APC PM fiber mating when using this gel, since that depends on various factors such as wavelength, MFD, core-to-core concentricity of the fibers, and tolerancing of ferrules and mating sleeves. Generally, there wouldn't be major improvements expected for FC connectors, since those are contact-based connectors and index matching gel provides maximum benefits when used in the presences of an air-gap between fibers. Keith Hodge
(posted 2020-11-23 11:26:02.307) Would be nice if you could add / include the thread spec on the drawing.
I was expecting a 3/8"-32 thread like many other ST mating sleeves. Looks like yours is a 3/8"-24 thread... I'll have to change something. YLohia

Is it possible to manufacture the ADAFC3 in such an order, that the polarisation states (or keyholes) are aligned at 45°? By this it would be possible to rotate the polarisation state without any additional component.

(posted 2019-07-30 10:22:56.88) Hi Thorlabs,
The question is about PM Fibre Mating Sleeve. We want to connect two PM Patch Cable, PANDA, 780 nm, FC/APC, fibres together. The input fibre would have about 1W of optical power. Would the second fibre be damaged if we used PM fibre mating sleeve since the optical power is above the damage threshold specified for this PM fibre? If yes, any advice on what to use to connect two APC terminated fibres when the optical power is about 1W? YLohia
(posted 2019-07-30 11:11:34.0) Hello, thank you for contacting Thorlabs. We recommend splicing the two fibers together for such high power applications. The connectors typically fail around power levels of ~300 mW. Jean-Baptiste Le Bouquin
(posted 2019-04-09 12:34:35.633) Can you explicit the characteristic of the sleeves used in ADAFCPM2. Are they Zirconia ceramic ? Thanks, JB YLohia
(posted 2019-04-09 02:38:03.0) Hello JB, thank you for contacting Thorlabs. The housing is made of nickel plated brass and the sleeve is zirconia ceramic. Ian Hill
(posted 2019-03-26 12:40:28.017) Hi, Part ADAFC4 is a solid piece as far as I can see so why is it not spec'd for PM? Thanks. YLohia
(posted 2019-03-26 03:04:57.0) Hello, thank you for contacting Thorlabs. The ADAFC4 is not a single piece. The ceramic sleeve inside that holds the ferrule is not as tightly toleranced as the one on the ADAFCPM2. The latter also has a tighter tolerance on the alignment key slots to ensure polarization axis match between two fibers. carlos.montero

(posted 2015-03-11 11:43:34.897) Hi.
In my system I want to couple several uWs of a narrow-band laser emission in a fiber and transfer it to an optical detector. There should be two mating sleeves: on a wall of a sealed casing and on a panel of a rack box.
Question: which fibers/connectors should I use to minimize transmission deviation of the whole fiber chain by dis- and reconnection of the fiber patches? Overall transmission is not important.
Fiber type - preferably MM for a better coupling. Wavelengths: separate fiber chains for 532nm, 905nm, 1064nm and 1570nm.

(posted 2015-01-30 17:17:42.243) Hi, I want to connect two PM fibers with both FC/APC connectors (narrow key). Which Mating Sleeve should I choose to achieve the best matching of polarization axis AND the lowest insertion loss?
The website states: ADAFC3 or ADAFC4 has IL < 0.5 dB (but not mentioning PM matching performance). ADAFCPM2 has "best matching of polarization axis" but IL < 1.0 dB (which is higher than ADAFC3 or 4). The posted comment of jlow (2013-11-25 08:46:59.0) says PM Fiber Mating Sleeves have IL around 0.5 dB.
I would have expected that ADAFCPM2 also has better IL performance due to manufacturing from a single piece of metal.
Do ADAFC3 and ADAFC4 really have same IL performance?
Thanks for helping! jlow

(posted 2013-07-26 13:31:43.36) Advantage of PC-PC over APC-APC?
Hello! In the group I am working, all the FC-fiber-fiber connections using mating sleeves are done using PC connections, as I understand mostly for historical reasons. I would like to switch to APC-APC connections in the future to reduce reflexions, but I would like to be sure: Is a coupling APC-APC as efficient as a coupling PC-PC (using e.g. a sleeve like ADAFCPM2)? Are there any other disavantages to APC-APC over PC-PC? Thanks! pbui
(posted 2013-08-01 14:11:00.0) Response from Phong at Thorlabs: When mating two FC/PC or FC/APC connectors together, there should be no change in the back reflection measurement since the physical contact of the two ferrules eliminates the air interface, effectively giving you zero reflection. Insertion losses can stem from fiber core to fiber core concentricity and face angle alignment.
With that said, there are no disadvantages for APC-APC mating; it functions exactly the same way as PC-PC mating. You should use narrow key mating sleeves like ADAFC3 instead of wide key like ADAFC1. Either is fine for FC/PC because since there is no angle on the ferrule, alignment would not be affected by the slop in the key. For APC-APC, you need the 8 degree angle of each ferrule to be aligned to get a good connection. jlow
(posted 2012-12-20 14:46:00.0) Response from Jeremy at Thorlabs: In the ADAFCSMA1, the two fiber tip would make physical contact. Inside the part is a stainless steel sleeve. I will e-mail you to discuss the tolerance of the part that you are looking for. alexandre.pichon-ajilon

(posted 2011-09-29 18:22:00.0) Response from Laurie at Thorlabs to cqedgg: Thank you for noting your desire to directly connect FC/PC and FC/APC-terminated fiber patch cables with a mating sleeve. Unfortunately, we've done some research that indicates that currently there isn't a way to physically make a mating sleeve design that will enable this functionality. Given that a direct mating sleeve solution isnot currently feasible, we would typically suggest one of two options. If you already own the patch cables, you could consider purchasing the appropriate mating sleeves (you'll need one FC/PC to FC/PC version and one FC/APC to FC/APC version) and one of our hybrid patch cables: http://thorlabs.com/NewGroupPage9.cfm?ObjectGroup_ID=5002&pn=P5-2000-PCAPC-1 Alternatively, if you do not already own the cables, Thorlabs does provide custom patch cable services, and we can make you a patch cable that has an FC/PC connector on one end and an FC/APC connector on the other.

Thorlabs的G608N3折射率匹配凝胶是一种透明的光耦合化合物，用来降低波导组件连接处的信号衰减。两个光纤端面中间的空气层会引起明显的信号光折射，因为空气和信号光波导之间存在较大差别的光阻抗。
光耦合化合物G608N3是按照所需透明度、纯度和折射率等光学属性配置的，以尽量降低信号损耗，同时能够灵活地机械连接坚固部件。与质地较硬的光学环氧树脂不同，这种软凝胶有粘弹性，可以补偿精密光学部件的不同热膨胀，并且不会引入过多的应力和脱层。残余物可以采用甲醇或异丙醇清洗。
这种材料在很多器件中还有一种额外的功效：它们能够让灵敏的光学部件不受环境灰尘或液体影响。此凝胶经过配比以保持超净、不发黄和不受x射线、紫外或阳光照射影响。材料释气少，挥发低，且没有吸光的微小粒子。总之，这种光学产品是一种化学稳定、无毒性的合成材料，工作温度范围较宽，适合要求高稳定度和长时间使用的应用。
下表给出了使用凝胶时信号损耗降低的具体数据。每支注射器有3 cc折射率匹配凝胶。折射率匹配凝胶还可以用于填充我们的光纤连接套件。
