11). Hoʻopili ʻo RoHS a me ke alakaʻi ʻole

Nā noi:

1). 1000Base-LX Ethernet

2). Nā Pūnaewele Metro/Access

3). 1×Fiber Channel

4). Nā loulou Optical ʻē aʻe

wehewehe:

ʻO JHA5420D-35 Transceivers kahi hana kiʻekiʻe, ʻoi aku ka maikaʻi o ka module i loaʻa kahi LC optics interface. Ua kūpono lākou me ka Small Form Factor Pluggable Multi-Sourcing Agreement (MSA) a me nā hana diagnostics Digital i loaʻa ma o ka 2-wire serial bus i kuhikuhi ʻia ma SFF-8472. Hoʻohana ka ʻāpana hoʻokipa i kahi mea hoʻokipa PIN a hoʻohana ka transmitter i kahi laser 1310 nm FP, a hiki i ka 14dB link budge e hōʻoia i kēia module 1000Base-LX Ethernet 20km noi.

• Nā helu kiʻekiʻe loa

•Paipai ʻiaKaiapuni hana:

•Nā hiʻohiʻona uila(T_ON= -40 a 85°C, VCC = 3.135 a 3.465 Volts)

Nānā:

1. Hoʻopili ʻia ʻo AC.
2. A i ʻole kaapuni hāmama.
3. I loko o 100 ohm hoʻopau ʻokoʻa.
4. 20 – 80 %
5. ʻO LOS ka LVTTL. Hōʻike ka Logic 0 i ka hana maʻamau; hōʻike ka loiloi 1 ʻaʻohe hōʻailona i ʻike ʻia.
6. Hoʻopili ʻia nā kikoʻī transceiver āpau me ka modulation sinusoidal lako mana o 20 Hz a i 1.5MHz a hiki i ka waiwai kikoʻī i hoʻohana ʻia ma o ka pūnaewele kānana mana i hōʻike ʻia ma ka ʻaoʻao 23 o ka Small Form-factor Pluggable (SFP) Transceiver Multi-Source Agreement (MSA) , Kepakemapa 14, 2000.

•Nā ʻāpana Optical (T_ON= -40 a 85°C, VCC = 3.135 a 3.465 Volts)

Nānā

1. Hoʻokuʻu ʻia ka mana optical i SMF.
2. 20-80%.
3. Ua helu ʻia ka huina jitter i hāʻawi ʻia mai nā ana DJ a me RJ me ka hoʻohana ʻana iā TJ = RJ + DJ. Hoʻohālikelike ʻia ʻo RJ i hāʻawi ʻia no 1 × 10-12 BER ma ka hoʻonui ʻana i ka jitter RMS (ana ʻia ma ka ʻaoʻao hoʻokahi ala a hāʻule paha) mai ka oscilloscope e 14. No kēlā me kēia FC-PI (Papa 9 - SM jitter output, note 1), ka mea i hāʻawi ʻia. ʻAe ʻia ʻo RJ e hoʻonui ma luna o kona palena inā e emi iho ka DJ i hāʻawi ʻia ma lalo o kona mau palena, ʻoiai ʻo ka DJ a me TJ i hoʻopuka ʻia e noho i loko o kā lākou kikoʻī. ʻO FC-PI nā palena kiʻekiʻe me ka hihia ʻino loa i kuhikuhi ʻia i ka hoʻokomo jitter ʻāpana.
4. Ana ʻia me PRBS 2^7-1i ka hora 10^-12BER

Nā memo:

1. Hoʻokaʻawale ʻia ka ʻāina kaapuni mai ka lepo chassis.
2. Hoʻopau ʻia ka hoʻopuka laser ma TDIS >2.0V a i ʻole wehe ʻia, hiki iā TDIS
3. Pono e huki ʻia me 4.7k - 10 kohms ma luna o ka papa hoʻokipa i ka volta ma waena o 2.0V a me 3.6V. Huki ʻo MOD_DEF(0) i ka laina haʻahaʻa e hōʻike ai ua hoʻopili ʻia ka module.
